Description

Technical Field

[0001] The present application relates to the technical field of servers, and in particular to a computing device. Background Art

[0002] Data centers usually include multiple computing devices, and computing devices may include multiple servers, which can provide computing services. Among them, the maximum power of a computing device is limited. Therefore, as the computing power of the server increases, the power of the server gradually increases, resulting in a small number of servers that can be installed in the computing device, resulting in a low server shelf rate. Summary of the invention

[0003] An object of an embodiment of the present application is to provide a computing device for improving the shelf rate of servers in the computing device.

[0004] To achieve the above objectives, the embodiments of the present application provide the following technical solutions:

[0005] On the one hand, a computing device is provided. The computing device includes a power conversion device, an energy storage device, a plurality of servers and a device management unit. The input end of the power conversion device is used to connect to a second AC line. The energy storage device is connected to the output end of the power conversion device. Each server includes a first input end and a second input end, the first input end of each server is used to connect to a first AC line, and the second input end of each server is connected to the output end of the power conversion device and the output end of the energy storage device. The device management unit is electrically connected to the plurality of servers, and the device management unit is used to: when the actual power value of the computing device is greater than the first power threshold, control the plurality of servers to draw power from the AC line and the energy storage device, wherein drawing power from the AC line includes drawing power from the first AC line, and / or drawing power from the second AC line through the power conversion device.

[0006] In the above computing device, by setting a power conversion device and an energy storage device in the computing device, the power conversion device can supply power to the energy storage device. Among them, the second AC line can supply power to multiple servers through the power conversion device, and the first AC line can supply power to multiple servers. When the actual power value of the computing device is greater than the first power threshold, both the energy storage device and the AC line can supply power to multiple servers, thereby increasing the maximum power of the computing device. Therefore, more servers can be deployed in the computing device, thereby increasing the shelf rate of servers in the computing device.

[0007] In some embodiments, the device management unit is also used to: when the actual power value is greater than the first power threshold, control the AC power obtained by multiple servers from the AC line so that the power loaded by the AC line is the first power threshold, and the power loaded by the energy storage device is the power difference between the actual power value and the first power threshold.

[0008] The energy storage device can load the portion of the actual power value of the computing equipment that exceeds the first power threshold, thereby increasing the shelf rate of the computing equipment and reducing the vacancy rate of the cabinet.

[0009] In some embodiments, the device management unit is electrically connected to the energy storage device; the device management unit is also used to: when the actual power value is greater than the first power threshold, control the output voltage of the power conversion device to be lower than the output voltage of the energy storage device, so that the energy storage device is in a discharging state.

[0010] Among them, by controlling the output voltage of the power conversion device to be lower than the output voltage of the energy storage device, the energy storage device can be placed in a discharge state, and thus the energy storage device can supply power to the server.

[0011] In some embodiments, the device management unit is electrically connected to the energy storage device; the device management unit is also used to: obtain the remaining capacity of the energy storage device, adjust the capped power of the computing device according to the remaining capacity, and control the actual power value of the computing device to be less than or equal to the capped power.

[0012] Among them, when the remaining capacity of the energy storage device is different, the power that the energy storage device can provide is different. Therefore, the maximum power of the computing device is different. By adjusting the capped power of the computing device according to the remaining capacity, and controlling the actual power value of the computing device to be less than or equal to the capped power, the maximum power of the computing device can be made not to exceed the power limit that the energy storage device and the AC line can load, thereby avoiding power failure of the computing device due to insufficient remaining capacity of the energy storage device.

[0013] In some embodiments, the device management unit is further used to: when the actual power value of the computing device is less than the first power threshold, control the power conversion device to charge the energy storage device.

[0014] Among them, when the actual power value of the computing device is less than the first power threshold, the power conversion device charges the energy storage device, which can ensure that the energy storage device has sufficient capacity, so that the energy storage device can provide more power to the computing device, thereby increasing the maximum power of the computing device. In addition, when the actual power value of the computing device is less than the first power threshold, that is, when the energy storage device does not supply power to multiple servers, the power conversion device charges the energy storage device, thereby avoiding the energy storage device being in a charging state and a power supply state at the same time, thereby extending the service life of the energy storage device.

[0015] In some embodiments, the server includes a first switching power supply, a second switching power supply and multiple loads, the first switching power supply and the second switching power supply are both connected to the multiple loads, the multiple loads include a management chip, the management chip is communicatively connected to the first switching power supply, the second switching power supply and a device management unit, the first switching power supply is a first input end, and the second switching power supply is a second input end; the device management unit is used to: when the actual power value is greater than the first power threshold, control the first switching power supply and the second switching power supply to jointly power the multiple loads through the management chip, or control the second switching power supply to power the multiple loads through the management chip.

[0016] Among them, when the actual power value is greater than the first power threshold, the first switching power supply is powered by the AC line, and the equipment management unit can control the second switching power supply to draw power from the energy storage device. At this time, the first switching power supply and the second switching power supply can jointly power multiple loads, and then the AC line and the energy storage device can jointly power the server.

[0017] In some embodiments, multiple servers include first-class servers and / or second-class servers, wherein servers that can draw power from a first AC line are first-class servers, and servers that cannot draw power from the first AC line are second-class servers; the device management unit is also used for: when an actual power value is greater than a first power threshold, controlling a first switching power supply and a second switching power supply of the first-class server through a management chip of the first-class server to jointly power multiple loads of the first-class server; and / or controlling a second switching power supply of the second-class server through a management chip of the second-class server to power multiple loads of the second-class server.

[0018] Among them, when the actual power value is greater than the first power threshold, the first switching power supply of the first type of server can draw power from the first AC line, and the device management unit can control the second switching power supply of the first type of server to draw power from the energy storage device, so that the first AC line and the energy storage device can jointly power the first type of server. The first switching power supply of the second type of server cannot draw power from the second AC line, and the second switching power supply of the second type of server can draw power from the first AC line through the power conversion device, and the device management unit can control the second switching power supply of the second type of server to draw power from the energy storage device, so that the first AC line and the energy storage device can jointly power the second type of server.

[0019] In some embodiments, the first switching power supply includes a first processing chip, which is electrically connected to a management chip, and is used to obtain the input power of the first switching power supply and send it to the management chip; the second switching power supply includes a second processing chip, which is electrically connected to the management chip, and is used to obtain the input power of the second switching power supply and send it to the management chip; the management chip is used to determine the power of the server based on the input power of the first switching power supply and the input power of the second switching power supply, and send it to the device management unit; the device management unit is used to determine the actual power value of the computing device based on the power of multiple servers and the power of the device management unit.

[0020] The first processing chip can send the input power of the first switching power supply obtained by it to the management chip, and the second processing chip can send the input power of the second switching power supply obtained by it to the management chip. The management chip can determine the power of the server where the management chip is located according to the sum of the input power of the first switching power supply and the input power of the second switching power supply. The device management unit can determine the actual power value of the computing device according to the power of the server obtained by the management chip.

[0021] In some embodiments, the device management unit is further used to: when the actual power value is less than or equal to the first power threshold, control the multiple servers to draw power from the AC line.

[0022] Among them, when the actual power value is less than the first power threshold, the AC line supplies power to multiple servers, thereby reducing the power consumption of the energy storage device and ensuring that the energy storage device has sufficient remaining capacity, thereby increasing the power that the energy storage device can provide, and further increasing the maximum power of the entire cabinet of computing equipment.

[0023] In some implementations, the server includes a first switching power supply, a second switching power supply, and a plurality of loads, the first switching power supply and the second switching power supply are both connected to the plurality of loads, the plurality of loads include a management chip, the management chip is communicatively connected with the first switching power supply, the second switching power supply, and a device management unit, the first switching power supply is a first input terminal, and the second switching power supply is a second input terminal. The device management unit is used to: when the actual power value is less than or equal to the first power threshold, the management chip can be used to control the first switching power supply or the second switching power supply to power the plurality of loads in the server.

[0024] If the first AC line is normal and the first switch power supply of the server is normal, the first switch power supply of the server supplies power to multiple loads. If the first AC line is abnormal or the first switch power supply of the server is abnormal, the second switch power supply of the server supplies power to multiple loads.

[0025] In some embodiments, multiple servers include first-class servers and / or second-class servers, wherein servers that can draw power from a first AC line are first-class servers, and servers that cannot draw power from the first AC line are second-class servers; the device management unit is used to: when an actual power value is less than or equal to a first power threshold, control a first switching power supply of the first-class server to draw power from the AC line through a management chip of the first-class server, so that the first switching power supply of the first-class server supplies power to multiple loads of the first-class server; and / or control a second switching power supply of the second-class server to draw power from the AC line, so that the second switching power supply of the second-class server supplies power to multiple loads of the second-class server.

[0026] When the actual power is less than the first power threshold, the first switch power supply of the first type of server can be powered from the first AC line, and the second switch power supply of the second type of server can be powered from the second AC line through the power conversion device, thereby preventing the second type of server from losing power.

[0027] In some embodiments, the computing device also includes: a switch, the switch is electrically connected to the first AC line, the power conversion device and the energy storage device, the switch includes a first communication interface and multiple second communication interfaces, the first communication interface is connected to the device management unit and the multiple second communication interfaces, and the second communication interface is connected to the management chip of the server.

[0028] The first communication interface is connected to the device management unit, and the second communication interface is connected to the management chip of the server. The first communication interface is connected to the second communication interface, so the device management unit can communicate with the management chip of the server through the first communication interface and the second communication interface, and then the device management unit can send a management signal to the management chip, so that the server can be controlled through the management chip.

[0029] On the other hand, a computing device is provided. The computing device includes: an energy storage device, multiple servers and a device management unit.

[0030] In the above computing device, by setting an energy storage device in the computing device, and allowing the energy storage device and the AC line to power multiple servers, the maximum power of the computing device can be increased. Therefore, more servers can be deployed in the computing device, thereby increasing the shelf rate of servers in the computing device.

[0047] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in some embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present disclosure.

[0051] Figure 1 A structural diagram of a data center provided for some embodiments of the present application.

[0052] See also Figure 1 The embodiment of the present application provides a data center 2000. The data center 2000 is a global collaborative specific device network used to implement data transmission, acceleration, display, calculation and storage functions on the Internet (Chinese name: Internet) network infrastructure.

[0053] The data center 2000 may include multiple computing devices 1000 , and the computing devices 1000 may be whole cabinet servers.

[0054] Multiple computing devices 1000 may be displayed in the computer room.

[0055] Figure 2 for Figure 1 A block diagram of a computing device in .

[0056] See also Figure 2 The computing device 1000 may include a cabinet 100 and a plurality of servers 200 . The plurality of servers 200 may be located in the cabinet 100 , so that the cabinet 100 can protect the servers 200 .

[0057] Among them, multiple servers 200 can be stacked in the same cabinet 100 to improve the space utilization of the data center 2000 and reduce space costs.

[0058] In this embodiment, in addition to the server 200, the computing device 1000 may also include a workstation, a storage, a switch or a repeater, etc.

[0059] Figure 3 It is a structural block diagram of a computing device 1000 in the related art.

[0060] See also Figure 3 The server 200 in the computing device 1000 can be electrically connected to two AC lines, and both AC lines can supply power to the server 200, thereby ensuring the normal operation of the server 200.

[0061] Among them, the number of servers 200 deployed in the computing device 1000 may be related to the total power of the computing device 1000 and the power of the servers 200 .

[0062] The following describes how to deploy the number of servers 200 according to the total power of the computing device 1000 .

[0063] Figure 4 for Figure 3 FIG. 1 is a graph showing a change in power P of the computing device 1000 over time t.

[0064] See also Figure 4 , the power of the computing device 1000 may include the basic power of the whole cabinet (Ptyp1) and the maximum power of the whole cabinet (Pmax1). Among them, the basic power of the whole cabinet is the power of the computing device when it is running stably, and the maximum power of the whole cabinet is the power of the computing device when it is running at full load. The power of the computing device 1000 is different at different times due to different running services. For example, when the computing device 1000 is running stably, the power of the computing device 1000 is less than or equal to the basic power of the whole cabinet. When the business of the computing device 1000 increases, its power is greater than the basic power of the whole cabinet and less than the maximum power of the whole cabinet. When the business of the computing device 1000 reaches a peak, the power of the computing device 1000 can reach the maximum power of the whole cabinet. Among them, the maximum power of the whole cabinet can be equal to the maximum power that the AC line can provide for the computing device 1000.

[0065] For example, the basic power of the entire cabinet of computing device 1000 is 4 KW, and the maximum power of the entire cabinet is 5 KW.

[0066] The power of server 200 may include a single basic power (Ptyp2) and a single maximum power (Pmax2), wherein the single basic power is the power of the server when it is running stably, and the single maximum power is the power of the server when it is running at full load. When server 200 is running stably, the power of server 200 is less than or equal to the single basic power. When the business of server 200 increases, its power is greater than the single basic power and less than the single maximum power. When the business of server 200 reaches a peak, the power of server 200 can reach the single maximum power. For example, the single basic power of server 200 is 357W, and the single maximum power is 500W.

[0067] In the related art, the maximum power Pmax1 of the entire cabinet of the computing device 1000 may be equal to the maximum AC power (Pac-max), where the maximum AC power is the maximum power that the AC line can provide to the computing device 1000 .

[0068] The number of servers 200 may be equal to the value obtained by dividing the maximum AC power by the maximum power of a single server 200. For example, the maximum AC power (i.e., the maximum power of the entire cabinet of the computing device 1000) is 5KW, and the maximum power of a single server 200 is 500W, wherein Pac-max÷Pmax2=5KW÷500W=10, and thus 10 servers 200 may be deployed in the computing device 1000.

[0069] Among them, the power supply plan of the data center 2000 has been finalized in the early design of the data center 2000, and correspondingly, the maximum AC power Pac-max has been finalized, so the maximum power Pmax1 of the entire cabinet of the computing device 1000 has been finalized.

[0070] For example, the maximum power Pmax1 of the entire cabinet of the computing device 1000 can be planned to be between 5KW and 8KW. As the computing power of the server 200 gradually increases, the power of a single server 200 inside the computing device 1000 gradually increases. Therefore, the number of servers 200 that can be placed in the cabinet 100 of a computing device 1000 decreases, resulting in a high vacancy rate of the cabinet 100. If the number of servers 200 continues to increase in the cabinet 100, the maximum power Pmax1 of the entire cabinet of the computing device 1000 will exceed the maximum AC power Pac-max. At this time, the computer room needs to be renovated. However, the transformation of the data center 2000 is difficult and takes a long time. Therefore, it is difficult to increase the power of a single computing device 1000, and it is difficult to solve the problem of a high vacancy rate of the cabinet 100.

[0071] In this embodiment, each server 200 in the computing device 1000 can perform model energy consumption training to count the historical power changes of each server 200, and correct the capped power of each server 200 according to the actual power of each server 200. After correcting the capped power of each server 200, the power of the entire cabinet of the computing device 1000 has a margin, and then the number of servers 200 deployed in the computing device 1000 can be increased, thereby increasing the density of the servers 200.

[0072] Among them, the capped power of server 200 can be used to limit the actual power of server 200. After the capped power of server 200 is determined, the actual power of server 200 will not exceed the capped power. If the business of server 200 suddenly increases at a certain moment, causing the actual power of server 200 to increase, the power of at least part of the equipment in server 200 can be reduced, for example, by reducing the speed of the fan in server 200 to reduce the power of the fan, thereby reducing the actual power of server 200, and thus the actual power of server 200 is made below the capped power of server 200.

[0073] Table 1 is a comparison table of capped powers of each server 200 in the computing device 1000 before and after the capped powers are corrected.

[0074]

[0075] Table 1

[0076] Please refer to Table 1. For example, the computing device 1000 includes 10 servers 200. In Table 1, the 10 servers 200 are sequentially referred to by the labels U1, U2, U3, ..., U10. Before the capped power of the 10 servers 200 is corrected, the power of each server 200 is 1000W. At this time, the total power budget of the computing device 1000 is 10000W. The total power budget of the computing device 1000 can be understood as the maximum total power required by the computing device 1000 to ensure the normal operation of all devices in the computing device 1000 (such as the server 200).

[0077] After the capped power of the ten servers 200 is corrected, the capped power of server U1 is 400 W, the capped power of server U2 is 800 W, the capped power of server U3 is 600 W, the capped power of server U4 is 1200 W, the capped power of server U5 is 800 W, the capped power of server U6 is 500 W, the capped power of server U7 is 1000 W, the capped power of server U8 is 400 W, the capped power of server U9 is 700 W, and the capped power of server U10 is 1100 W. At this time, the total power budget of the computing device 1000 is 7500 W.

[0078] Compared with before the power capping of server 200 was corrected, the total power budget of computing device 1000 was reduced by 2500W. Therefore, the computing device 1000 can have a power margin of 2500W, and then three more servers 200 can be added to the cabinet 100, thereby increasing the deployment density of server 200, reducing the vacancy rate of cabinet 100, and increasing the computing power of computing device 1000.

[0079] In the above embodiment, after the capped power of the computing device 1000 is corrected, the vacancy rate of the cabinet 100 can be reduced.

[0080] Next, some other embodiments that can reduce the vacancy rate of the cabinet 100 are introduced.

[0081] Figure 5 for Figure 1 A structural block diagram of the computing device 1000 in FIG.

[0082] See also Figure 5, some other embodiments of the present application provide a computing device 1000. The computing device 1000 may include a cabinet 100, multiple servers 200, an energy storage device 300, a device management unit 400, a power conversion device 500 and a power distribution unit (PDU) 600. Among them, multiple servers 200, energy storage devices 300, device management units 400, power conversion devices 500 and power distribution units 600 may be arranged in the cabinet 100. Among them, the number of servers 200 may be 2, 3 or more. In the embodiments of the present application, the number of servers 200 is not limited. In Figure 3 In the embodiment, a computing device 1000 including three servers 200 is taken as an example to illustrate some embodiments of the present application.

[0083] Each server 200 includes a first input terminal and a second input terminal, wherein the first input terminal of each server 200 is connected to the AC line, and the second input terminal of each server 200 is connected to the output terminal of the energy storage device 300 and the output terminal of the power conversion device 500. The input terminal of the power conversion device 500 is electrically connected to the AC line, and the output terminal of the power conversion device 500 is also connected to the input terminal of the energy storage device 300 and the device management unit 400.

[0084] In this embodiment, the number of power distribution units 600 can be two, wherein the first input end of each server 200 can be connected to one power distribution unit 600 and connected to the AC line through the power distribution unit 600, and the second input end of each server 200 can be connected to another power distribution unit 600 and electrically connected to the output end of the energy storage device 300 and the output end of the power conversion device 500 through the power distribution unit 600.

[0085] The power distribution unit 600 is provided with a plurality of sockets, and each server 200 can be plugged into a corresponding socket via a cable.

[0086] Among them, the AC line can provide 220V AC power.

[0087] The input end of the power conversion device 500 is connected to an AC line, and the power conversion device 500 can convert the AC signal received at the input end into a DC signal, and the DC signal can be output from the output end. For example, the power conversion device 500 can be an AC / DC power supply device.

[0088] For example, the voltage of the DC signal formed by the power conversion device 500 may be 240V. In addition, the voltage of the DC signal formed by the power conversion device 500 may also be 48V, which are not listed here one by one.

[0089] The output end of the power conversion device 500 may be electrically connected to the input end of the energy storage device 300, so that the power conversion device 500 can charge the energy storage device 300. For example, the energy storage device 300 may include a battery.

[0090] In addition, the output end of the power conversion device 500 can also be electrically connected to the device management unit 400, and then the power conversion device 500 can supply power to the device management unit 400. However, in other examples, the device management unit 400 can be connected to the output end of the energy storage device 300, and in this case, the energy storage device 300 can be used to supply power to the device management unit 400.

[0091] The device management unit 400 may be communicatively connected with the power conversion device 500 , so that the device management unit 400 may control the power conversion device 500 to charge the energy storage device 300 .

[0092] For example, the device management unit 400 and the power conversion device 500 may be communicatively connected via an I2C (Inter-Integrated Circuit) bus or a CAN (Controller Area Network) bus.

[0093] The device management unit 400 may also be connected to the energy storage device 300 for communication, so that the device management unit 400 may control the energy storage device 300 to supply power to the multiple servers 200 .

[0094] For example, the device management unit 400 and the energy storage device 300 may be communicatively connected via an I2C bus or a CAN bus.

[0095] The second input end of the server 200 may be connected to the output end of the power conversion device 500 , and thus the second input end of the server 200 may obtain power from the AC line through the power conversion device 500 .

[0096] The second input terminal of the server 200 may also be connected to the output terminal of the energy storage device 300 , so that the server 200 may draw power from the energy storage device 300 .

[0097] In addition, the first input terminal of the server 200 may be connected to an AC line, and thus the server 200 may draw power from the AC line.

[0098] The device management unit 400 can also be electrically connected to multiple servers 200, so that the device management unit 400 can control the server 200 to draw power from the AC line, or draw power from the AC line through the power conversion device 500, or draw power from the energy storage device 300. For example, the device management unit 400 and the server 200 can be connected to each other by wire or wireless communication.

[0099] Please continue reading Figure 5 In this embodiment, the AC line may include a first AC line and a second AC line. The input end of the power conversion device 500 may be connected to the second AC line, so the power conversion device 500 may draw power from the second AC line.

[0100] The first input end of each server 200 can be connected to the first AC line through a power distribution unit 600, and the second input end of each server 200 can be connected to the output end of the energy storage device 300 and the output end of the power conversion device 500 through another power distribution unit 600. The input end of the power conversion device 500 is connected to the second AC line, so that the second input ends of multiple servers are connected to the energy storage device 300 and the second AC line.

[0101] The second AC line and the first AC line can both independently supply power to the computing device 1000 .

[0102] Wherein, when the first AC line is normal, the first AC line can supply power to the server 200, and when the first AC line is abnormal, the power conversion device 500 can draw power from the second AC line, and convert the AC signal into a DC signal, and output it to the second input terminal of the server 200, so as to supply power to the server 200. In other words, the first AC line and the second AC line are each other's main and standby power supply lines, and when the first AC line is abnormal, the computing device 1000 can be powered by the second AC line, thereby reducing the occurrence of power failure of the server 200.

[0103] In addition, when the first AC line is normal but the first input end of some servers 200 is abnormal, the second input end of the server 200 with the abnormal first input end can draw power from the second AC line through the power conversion device 500, so as to avoid the server 200 with the abnormal first input end from being unable to operate normally, wherein the abnormal first input end means that the first input end of the server 200 cannot draw power from the second AC line.

[0104] For example, both the first AC line and the second AC line can provide 220V AC power.

[0105] Among them, the maximum power that the first AC line can provide is equal to the maximum AC power, and the maximum power that the second AC line can provide is equal to the maximum AC power. Since the first AC line and the second AC line are each other's main and standby power supply lines, the maximum value of the sum of the powers that the first AC line and the second AC line can provide is the maximum AC power. For example, the actual power provided by the first AC line is W1, and the actual power provided by the second AC line is W2. At this time, the maximum value of W1+W2 is equal to the maximum AC power. When W1 is equal to the maximum AC power, W2 is equal to 0; when W1 is equal to 0, W2 is equal to the maximum AC power. For example, the maximum AC power is 5KW.

[0106] In this embodiment, the device management unit 400 is used to: when the actual power value is less than or equal to the first power threshold, control the multiple servers 200 to draw power from the AC line. At this time, the AC line supplies power to the computing device 1000.

[0107] The device management unit 400 is also used to: when the actual power value is greater than the first power threshold, control the multiple servers 200 to draw power from the AC line and the energy storage device 300. At this time, the AC line and the energy storage device 300 jointly supply power to the computing device 1000.

[0108] The above-mentioned drawing power from the AC line includes drawing power from a first AC line and / or drawing power from a second AC line through a power conversion device 500 .

[0109] When the server 200 obtains power from the second AC line through the power conversion device 500 , the power conversion device 500 converts the AC power signal obtained from the second AC line into a DC power signal and outputs it to the second input terminal of the server 200 .

[0110] It can be understood that the above-mentioned multiple servers 200 draw power from the AC line and the energy storage device 300, including: multiple servers 200 all draw power from the AC line, and some servers 200 draw power from the energy storage device 300; or, each server 200 draws power from the AC line and the energy storage device 300.

[0111] In which, when the first AC line is normal and the first input terminals of all servers 200 can draw power from the first AC line, multiple servers 200 draw power from the first AC line, and at least some servers 200 draw power from the energy storage device 300. At this time, the AC signal provided by the first AC line can enter the server 200 from the first input terminal of the server 200, and the DC signal provided by the energy storage device 300 can enter the server 200 from the second input terminal of the server 200.

[0112] When the first AC line is abnormal, but the second AC line is normal, and the second input terminals of all servers 200 can draw power from the second AC line through the power conversion device 500, multiple servers 200 draw power from the first AC line, and at least some of the servers 200 draw power from the energy storage device 300. The second input terminals of at least some of the servers 200 simultaneously receive the DC power output by the power conversion device 500 and the DC power output by the energy storage device 300.

[0113] In the case where the first AC line is normal, the second AC line is normal, and the first input end of some servers 200 cannot draw power from the first AC line, the second input end of the server 200 with an abnormal first input end can draw power from the second AC line through the power conversion device 500, and the second input end of the server 200 with an abnormal first input end can draw power from the energy storage device 300. The first input end of the server 200 with a normal first input end can draw power from the first AC line. The abnormal first input end means that the first input end of the server 200 cannot draw power from the first AC line, and the normal first input end means that the first input end of the server 200 can draw power from the first AC line.

[0114] The actual power value of the computing device 1000 may be the sum of the powers of all power-consuming devices in the computing device 1000, wherein the power-consuming device refers to a device that does not have a power supply function, for example, the power conversion device 500 and the energy storage device 300 do not belong to power-consuming devices, while the server 200, the device management unit 400 and the power distribution unit 600 belong to power-consuming devices. At this time, the actual power value of the computing device 1000 may be the sum of the powers of multiple servers 200, the power of the device management unit 400 and the power distribution unit 600. In addition, in some other examples, in the computing device 1000, except for the server 200, the power of other devices is small and can be ignored. At this time, the actual power value of the computing device 1000 may be the sum of the actual powers of multiple servers 200.

[0115] Among them, the maximum power that the AC line can provide to the computing device 1000 can be the first power threshold, that is, the maximum AC power Pac-max is equal to the first power threshold. The energy storage device 300 and the AC line can both power multiple servers 200. At this time, the maximum power Pmax1 of the entire cabinet of the computing device 1000 can be equal to the sum of the power that the AC line can provide to the computing device 1000 and the power that the energy storage device 300 can provide to the computing device 1000, that is, the maximum power Pmax1 of the entire cabinet is equal to the sum of the maximum AC power Pac-max and the power that the energy storage device 300 can provide to the computing device 1000. Therefore, the maximum power Pmax1 of the entire cabinet of the computing device 1000 is greater than the power that the AC line can provide to the computing device 1000 (that is, the maximum AC power Pac-max). In summary, the embodiment of the present application can increase the maximum power Pmax1 of the entire cabinet of the computing device 1000 by setting the energy storage device 300 in the computing device 1000. Therefore, more servers 200 can be deployed in the computing device 1000, thereby increasing the shelf rate of the servers 200 in the computing device 1000 and reducing the vacancy rate of the cabinet 100 without the need to renovate the computer room.

[0116] In this embodiment, the device management unit 400 is used to: when the actual power value is less than or equal to the first power threshold, control the multiple servers 200 to draw power from the AC line. In this case, the AC power obtained by the multiple servers 200 from the AC line is the actual power value. Among them, the AC power obtained by the multiple servers 200 from the AC line can be the sum of the power provided by the AC line to the multiple servers 200, and the sum of the power provided by the AC line to the multiple servers 200 can be the sum of the power provided by the first AC line to the multiple servers 200 and the sum of the power provided by the second sub-AC through the power conversion device 500 to the multiple servers 200.

[0117] The device management unit 400 is also used to: when the actual power value is greater than the first power threshold, control the multiple servers 200 to draw power from the AC line and the energy storage device 300, so that the AC line and the energy storage device 300 jointly power the multiple servers 200, and control the AC power obtained by the multiple servers 200 from the AC line, so that the power carried by the AC line is the first power threshold, and the power carried by the energy storage device 300 is the power difference between the actual power value and the first power threshold. For the convenience of description, the power carried by the energy storage device 300 can be equal to the sum of the powers provided by the energy storage device 300 to the multiple servers 200.

[0118] For example, when the actual power value is greater than the first power threshold, the device management unit 400 can limit the sum of the powers obtained by multiple servers 200 from the AC line to be equal to the first power threshold. At this time, the energy storage device 300 can automatically load the part of the computing device 1000 that exceeds the first power threshold, that is, the energy storage device 300 can automatically load the power difference between the actual power value and the first power threshold, so that the sum of the powers obtained by multiple servers 200 from the energy storage device 300 is the power difference between the actual power value and the first power threshold.

[0119] For example, the first power threshold is 5 KW, and the actual power value of the computing device 1000 is 5.5 KW. At this time, the power loaded by the AC line is 5 KW, and the power loaded by the energy storage device 300 is 0.5 KW.

[0120] Among them, the energy storage device 300 can load the part of the actual power value of the computing device 1000 that exceeds the first power threshold, and then can increase the maximum power of the entire cabinet of the computing device 1000, thereby increasing the shelf rate of the computing device 1000 and reducing the vacancy rate of the cabinet 100.

[0121] In some examples, the first power threshold may be equal to the maximum power (i.e., the AC maximum power) provided by the AC line to the computing device 1000. The first power threshold may be referred to when the number of servers 200 deployed in the computing device 1000. For example, the number of servers 200 (N) may be equal to the first power threshold (i.e., the AC maximum power) divided by the basic power of a single server 200, i.e., N = Pac-max ÷ Ptyp2.

[0122] In the related art, the number of servers 200 is equal to the maximum AC power divided by the maximum power of a single server 200, that is, N = Pdc-max ÷ Pmax.

[0123] Since the basic power of a single server 200 is less than the maximum power of a single server 200, in the embodiment of the present application, the number of servers 200 that can be set in the cabinet 100 is greater than the number of servers 200 that can be set in the cabinet 100 in the related art. Therefore, the embodiment of the present application can increase the number of servers 200 in the computing device 1000 and increase the shelf rate of the servers 200 in the cabinet 100, thereby reducing the vacancy rate of the cabinet 100.

[0124] For example, the maximum AC power is 5KW, the basic power of a single server 200 is 357W, and the maximum power of a single server is 500W. In the embodiment of the present application, N=Pac-max÷Ptyp2=5KW÷357W≈14, so in the embodiment of the present application, 14 servers 200 can be deployed in the cabinet 100 of the computing device 1000. In the related art, N=Pac-max÷Pmax2=5KW÷500W=10, so in the related art, 10 servers can be deployed in the cabinet 100 of the computing device 1000. In summary, the number of servers 200 that can be deployed in the cabinet 100 in the embodiment of the present application is greater than the number of servers 200 that can be deployed in the cabinet 100 in the related art, and thus the embodiment of the present application can increase the shelf rate of the servers 200 in the cabinet 100 and reduce the vacancy rate of the cabinet 100.

[0125] Figure 6 for Figure 1 Another structural block diagram of the computing device 1000 in FIG.

[0126] See also Figure 6 In this embodiment, the server 200 includes a first switching power supply 210, a second switching power supply 220 and a plurality of loads 230. Among them, the plurality of loads 230 may include a management chip 231. The input end of the first switching power supply 210 is connected to the power distribution unit 600, and is connected to the first AC line through the power distribution unit 600. The input end of the second switching power supply 220 is connected to the output end of the energy storage device 300 and the output end of the power conversion device 500 through another power distribution unit 600. The output end of the first switching power supply 210 and the output end of the second switching power supply 220 are both connected to the plurality of loads 230. The management chip 231 is connected to the first switching power supply 210, the second switching power supply 220 and the device management unit 400 in communication.

[0127] The first switching power supply 210 can be used as the first input terminal of the server 200; the abnormality of the first input terminal of the server 200 may include an abnormality of the first switching power supply 210 or an abnormality between the first switching power supply 210 and the first AC line. The second switching power supply 220 can be used as the second input terminal of the server 200. The abnormality of the second input terminal of the server 200 may include an abnormality of the second switching power supply 220 or an abnormality between the second switching power supply 220 and the second AC line.

[0128] For example, the multiple loads 230 in the server 200 may include a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), a hard disk, a fan, a network card, a PCIE (Peripheral Component Interconnect Express) card, a CPLD (Complex Programmable Logic Device), a BMC (Baseboard Manager Controller) and other devices that require power supply, which are not listed here one by one.

[0129] It should be noted that different computing devices have different names for BMC, for example, some computing devices are called BMC, some computing devices are called iLO (Integrated lights-out), and some computing devices are called Integrated Dell Remote Access Controller (iDRAC). Whether it is called BMC, iLO or iDRAC, it can be understood as the BMC in the embodiment of the present invention.

[0130] For example, the management chip 231 may be a BMC.

[0131] The input end of the first switching power supply 210 is connected to the first AC line, so that the AC signal provided by the first AC line can be input to the first switching power supply 210, and the first switching power supply 210 can convert the received AC signal into a DC signal and output it to the multiple loads 230 through the output end, thereby supplying power to the multiple loads 230. For example, the voltage of the DC signal output by the first switching power supply 210 can be 12V.

[0132] The input end of the second switching power supply 220 can be connected to the output end of the energy storage device 300 and the output end of the power conversion device 500, and then the DC signal output by the energy storage device 300 or the power conversion device 500 can be output to the second switching power supply 220, and the second switching power supply 220 can regulate the DC signal provided by the energy storage device 300 or the power conversion device 500, and output the regulated DC signal from the output end to multiple loads 230, so as to supply power to the multiple loads 230. For example, the second switching power supply 220 can regulate the DC signal output by the energy storage device 300 or the power conversion device 500 to a 12V DC signal.

[0133] When a server 200 draws power from an AC line, the first switching power supply 210 of the server 200 can draw power from the first AC line to supply power to multiple loads 230 in the server 200, or the second switching power supply 220 of the server 200 can draw power from the second AC line through the power conversion device 500 to supply power to multiple loads 230 in the server 200. When a server 200 draws power from an energy storage device 300, the second switching power supply 220 of the server 200 can draw power from the energy storage device 300 to supply power to multiple loads 230 in the server 200.

[0134] Please continue reading Figure 6 In this embodiment, in the server 200, the first switch power supply 210 can be a main power supply, and the second switch power supply 220 can be a backup power supply.

[0135] For example, the management chip 231 is used to detect the input voltage of the first switching power supply 210 and the input voltage of the second switching power supply 220, and set the switching power supply whose input voltage is an AC voltage as the main power supply, and set the switching power supply whose input voltage is a DC voltage as the backup power supply. In an embodiment of the present application, the first switching power supply 210 is connected to the first AC line, so the input voltage of the first switching power supply 210 is an AC voltage. At this time, the first switching power supply 210 serves as the main power supply. The second switching power supply 220 is connected to the energy storage device 300 and the power conversion device 500, and the voltages input from the energy storage device 300 and the power conversion device 500 to the second switching power supply 220 are both DC voltages. Therefore, the input voltage of the second switching power supply 220 is a DC voltage. At this time, the second switching power supply 220 serves as a backup power supply.

[0136] In this embodiment, when the actual power value is less than or equal to the first power threshold, the management chip 231 can control the output voltage of the first switching power supply 210 (i.e., the main power supply) to be greater than the output voltage of the second switching power supply 220 (i.e., the backup power supply), so that the first switching power supply 210 is used as the main power supply to power multiple loads 230, and the second switching power supply 220 is used as the backup power supply. If the first switching power supply 210 cannot draw power from the first AC line, the management chip 231 can control the second switching power supply 220 to power multiple loads 230.

[0137] When the first AC line fails, the first switch power supplies 210 of the multiple servers 200 cannot draw power from the first AC line, that is, the first input terminals of the multiple servers 200 cannot draw power from the first AC line. At this time, the device management unit 400 can control the multiple servers 200 to draw power from the second AC line through the power conversion device 500.

[0138] When the first AC line is not faulty, but the first switching power supply 210 of a server 200 is faulty, then the first switching power supply 210 of the server 200 cannot draw power from the first AC line, that is, the first input end of the server 200 cannot draw power from the first AC line. At this time, the device management unit 400 can control the second switching power supply 220 of the server 200 to draw power from the second AC line through the power conversion device 500.

[0139] In this embodiment, when the actual power value is less than or equal to the first power threshold, the device management unit 400 can control the first switching power supply 210 or the second switching power supply 220 to power the multiple loads 230 in the server 200 through the management chip 231 .

[0140] If the first AC line is normal and the first switch power supply 210 of the server 200 is normal, the first switch power supply 210 of the server 200 supplies power to the multiple loads 230 .

[0141] If the first AC line is abnormal, or the first switch power supply 210 of the server 200 is abnormal, the second switch power supply 220 of the server 200 supplies power to the multiple loads 230 .

[0142] In this embodiment, when the actual power value is greater than the first power threshold, the device management unit 400 can control the first switching power supply 210 and the second switching power supply 220 through the management chip 231 to jointly power multiple loads 230, or control the second switching power supply 220 through the management chip 231 to power multiple loads 230.

[0143] If the first AC line is normal and the first switch power supply 210 of the server 200 is normal, the first switch power supply 210 and the second switch power supply 220 of the server 200 jointly supply power to the multiple loads 230 of the server 200 .

[0144] If the first AC line is abnormal, or the first switch power supply 210 of the server 200 is abnormal, the second switch power supply 220 of the server 200 supplies power to the multiple loads 230 .

[0145] Among them, when the first switching power supply 210 of the server 200 can draw power from the first AC line and the second switching power supply 220 is normal, when the actual power value is less than or equal to the first power threshold, the management chip 231 can control the first switching power supply 210 to supply power to multiple loads 230, and the second switching power supply 220 does not supply power to multiple loads 230.

[0146] For example, the management chip 231 can control the output voltage of the first switching power supply 210 to be greater than the output voltage of the second switching power supply 220, so that the first switching power supply 210 supplies power to multiple loads 230, and the second switching power supply 220 does not supply power to multiple loads 230. Of course, in other embodiments, the first switching power supply can also be controlled to supply power to multiple loads, while the second switching power supply does not supply power to multiple loads in other ways. The embodiment of the present application does not limit the method of controlling the first switching power supply to supply power to multiple loads, while the second switching power supply does not supply power to multiple loads, as long as the first switching power supply can supply power to multiple loads, while the second switching power supply does not supply power to multiple loads.

[0147] When the actual power value is greater than the first power threshold, the management chip 231 of the server 200 can control the first switch power supply 210 and the second switch power supply 220 to jointly power multiple loads 230. At this time, the second switch power supply 220 can draw power from the energy storage device 300, and the first switch power supply 210 can draw power from the first AC line. For example, the management chip 231 can control the output voltage of the second switch power supply 220 to be the same as or similar to the output voltage of the first switch power supply 210. When the output voltage of the second switch power supply 220 is similar to the output voltage of the first switch power supply 210, the voltage difference between the output voltage of the second switch power supply 220 and the output voltage of the first switch power supply 210 is less than or equal to the preset threshold. As long as the voltage difference between the output voltage of the second switch power supply 220 and the output voltage of the first switch power supply 210 is less than or equal to the preset threshold, the first switch power supply and the second switch power supply can jointly power multiple loads 230. Of course, in other embodiments, the first switch power supply 210 and the second switch power supply 220 can also be implemented by other methods to jointly power multiple loads 230. The embodiment of the present application does not limit the implementation manner in which the first switching power supply 210 and the second switching power supply 220 jointly supply power to multiple loads.

[0148] Please continue reading Figure 6 In this embodiment, when the actual power value is less than or equal to the first power threshold, the embodiment of the present application may include the following three scenarios:

[0149] If the first AC line is normal and the first switch power supplies 210 of the multiple servers 200 are normal, the first switch power supplies 210 of the multiple servers 200 draw power from the first AC line.

[0150] If the first AC line is abnormal, the device management unit 400 controls the second switching power supplies 220 of the multiple servers 200 through the management chips 231 of the multiple servers 200 to obtain power from the second AC line through the power conversion device 500 .

[0151] If the first AC line is normal, and the first switching power supply 210 of the first part server 200 is normal, and the first switching power supply 210 of the second part server 200 is abnormal, the first switching power supply 210 of the first part server 200 draws power from the first AC line, and the device management unit 400 controls the second switching power supply 220 of the second part server 200 to draw power from the second AC line through the power conversion device 500 through the management chip 231 of the second part server 200.

[0152] In this embodiment, when the actual power value is greater than the first power threshold, the embodiment of the present application may include the following three scenarios:

[0153] If the first AC line is normal and the first switching power supplies 210 of the multiple servers 200 are normal, the first switching power supplies 210 of the multiple servers 200 draw power from the first AC line, and the device management unit 400 controls the second switching power supplies 220 of at least some of the servers 200 to draw power from the energy storage device 300 through the management chip 231 of at least some of the servers 200.

[0154] If the first AC line is abnormal, the device management unit 400 controls the second switching power supplies 220 of the multiple servers 200 through the management chips 231 of the multiple servers 200 to draw power from the second AC line through the power conversion device 500, and at the same time controls the second switching power supplies 220 of at least some of the servers 200 through the management chips 231 of at least some of the servers 200 to draw power from the energy storage device 300.

[0155] If the first AC line is normal, and the first switch power supply 210 of the third part server 200 is normal, and the first switch power supply 210 of the fourth part server 200 is abnormal, the device management unit 400 controls the first switch power supply 210 of the third part server 200 to draw power from the first AC line through the management chip 231 of the third part server 200, and the device management unit 400 controls the second switch power supply 220 of the fourth part server 200 to draw power from the second AC line through the power conversion device 500 through the management chip 231 of the fourth part server 200, and controls the second switch power supply 220 of at least part of the third part server and the fourth part server to draw power from the energy storage device 300 through the management chip 231 of at least part of the servers 200.

[0156] In summary, the second switching power supply of the server 200 controlled by the device management unit 400 can draw power from the second AC line through the power conversion device 500. Therefore, when the first switching power supply 210 of the server 200 cannot be connected to the first AC line, the second switching power supply 220 of the server 200 can draw power from the second AC line through the power conversion device 500, thereby avoiding the problem of power failure of the server 200.

[0157] In this embodiment, the device management unit 400 controls the first switching power supply 210 and the second switching power supply 220 through the management chip 231. In some other embodiments, the device management unit 400 can be directly electrically connected to the first switching power supply 210 and the second switching power supply 220, and can then directly control the first switching power supply 210 and the second switching power supply 220.

[0158] Figure 7 2 is a power allocation diagram of the first type of server 201 and the second type of server 202 in the computing device 1000 when the actual power value is greater than the first power threshold. Figure 7 In the figure, the “×” on the line between the first switch power supply 210 of the second type server 202 and the load 230 indicates that the first switch power supply 210 of the second type server 202 cannot supply power to the load 230 of the second type server 202 .

[0159] See also Figure 7 In the embodiment of the present application, the server 200 that can draw power from the first AC line is defined as a first-type server 201 , and the server 200 that cannot draw power from the first AC line is defined as a second-type server 202 .

[0160] During the operation of the computing device 1000, the multiple servers 200 may include first-type servers 201 and / or second-type servers 202. In the case where the first AC line is normal and the first switch power supplies 210 of the multiple servers 200 are normal, the multiple servers 200 may all be first-type servers 201. In the case where the first AC line is normal, the server 200 with a normal first switch power supply 210 is the first-type server 201, and the server 200 with an abnormal first switch power supply 210 is the second-type server 202.

[0161] In this embodiment, when the actual power value is less than or equal to the first power threshold, the device management unit 400 is used to: control the first switching power supply 210 of the first type of server 201 to power multiple loads 230 of the first type of server 201; and / or control the second switching power supply 220 of the second type of server 202 to power multiple loads 230 of the second type of server 202 through the second AC line of the power conversion device 500.

[0162] The device management unit 400 is also used to: when the actual power value is greater than the first power threshold, control the first switching power supply 210 and the second switching power supply 220 of the first type of server 201 through the management chip 231 of the first type of server 201 to jointly power multiple loads 230 of the first type of server 201; and / or, control the second switching power supply 220 of the second type of server 202 through the management chip 231 of the second type of server 202 to power multiple loads 230 of the second type of server 202.

[0163] For example, when the actual power value is greater than the first power threshold, the device management unit 400 is used to: control the first switching power supply 210 of the first type of server 201 to supply power to multiple loads 230, and control the second switching power supply 220 of the first type of server 201 to draw power from the energy storage device 300, so that the first switching power supply 210 and the second switching power supply 220 of the first type of server 201 jointly supply power to multiple loads 230 of the first type of server 201; and / or, control the second switching power supply 220 of the second type of server 202 to draw power from the second AC line through the power conversion device 500, and control the second switching power supply 220 of the second type of server 202 to also draw power from the energy storage device 300, so that the second switching power supply 220 of the second type of server 202 supplies power to multiple loads 230.

[0164] Among them, when the actual power value is less than or equal to the first power threshold, and when the actual power value is greater than the first power threshold, if the first switching power supply 210 of the second type of server 202 cannot draw power from the AC line, the device management unit 400 can control the second switching power supply 220 of the second type of server 202 to draw power from the AC line, thereby avoiding the problem of power failure of the second type of server 202.

[0165] Please continue reading Figure 7 In this embodiment, the first switching power supply 210 includes a first processing chip 211 , which is electrically connected to the management chip 231 . The first processing chip 211 is used to obtain the input power of the first switching power supply 210 and send it to the management chip 231 .

[0166] The second switching power supply 220 includes a second processing chip 221 . The second processing chip 221 is electrically connected to the management chip 231 . The second processing chip 221 is used to obtain input power of the second switching power supply 220 and send it to the management chip 231 .

[0167] For example, the first processing chip 211 and the second processing chip 221 may both be DSPs (Digital Signal Processors).

[0168] The management chip 231 is used to determine the power of the server 200 according to the input power of the first switching power supply 210 and the input power of the second switching power supply 220 , and send the power to the device management unit 400 .

[0169] The sum of the input power of the first switching power supply 210 and the input power of the second switching power supply 220 is the power of the server 200 .

[0170] The first processing chip 211 may send the input power of the first switching power supply 210 obtained by it to the management chip 231, and the second processing chip 221 may send the input power of the second switching power supply 220 obtained by it to the management chip 231. The management chip 231 may determine the power of the server 200 where the management chip 231 is located according to the sum of the input power of the first switching power supply 210 and the input power of the second switching power supply 220.

[0171] The device management unit 400 is used to determine the actual power value of the computing device 1000 according to the power of the plurality of servers 200 and the power of the device management unit 400 .

[0172] In some examples, the actual power value of computing device 1000 may be equal to the sum of the powers of multiple servers 200 .

[0173] In other examples, the actual power value of the computing device 1000 may also be equal to the sum of the power of the device management unit 400 , the power of the switch 700 , the power of the power distribution unit 600 , and the power of the plurality of servers 200 .

[0174] Please continue reading Figure 7 In this embodiment, the device management unit 400 can also be used to: obtain the power (P1) of the server 200.

[0175] When the actual power value is greater than the first power threshold, the device management unit 400 can control the first switch power supply 210 and the second switch power supply 220 of the first type of server 201 through the management chip 231 of the first type of server 201 to simultaneously power multiple loads 230, wherein the power provided by the first switch power supply 210 is the first sub-power threshold (P2), and the power provided by the second switch power supply 220 of the first type of server 201 is the difference between the power of the first type of server 201 and the first sub-power threshold, i.e., P1-P2. The product of the first sub-power threshold P2 and the number of servers 200 is equal to the first power threshold.

[0176] Among them, when the actual power value is greater than the first power threshold, the management chip 231 of the first type server 201 can control the second switching power supply 220 and the first switching power supply 210 to jointly power multiple loads 230. At the same time, the device management unit 400 can also limit the output power of the first switching power supply 210 to the first sub-power threshold through the management chip 231, so that the power obtained by the first switching power supply 210 from the first AC line is the first sub-power threshold, and the output power of the second switching power supply 220 is the difference between the power of the server 200 and the first sub-power threshold, thereby limiting the power obtained by the second switching power supply 220 from the energy storage device 300 to the difference between the power of the server 200 and the first sub-power threshold.

[0177] For example, the management chip 231 can control the output voltage of the first switching power supply 210 to be lower than the output voltage of the second switching power supply 220, so as to limit the output power of the first switching power supply 210 to the first sub-power threshold. It can be understood that when the output voltage of the first switching power supply 210 is adjusted to be lower than the output voltage of the second switching power supply 220, it is necessary to ensure that the first switching power supply 210 and the second switching power supply 220 can jointly power multiple loads 230. For example, the voltage difference between the output voltage of the second switching power supply 220 and the first switching power supply 210 is less than or equal to the preset threshold. When the voltage difference between the output voltage of the second switching power supply 220 and the first switching power supply 210 is less than or equal to the preset threshold, the first switching power supply 210 and the second switching power supply 220 can jointly power multiple loads 230, and the output power of the first switching power supply 210 can be limited. Of course, the output power of the first type of server 201 can be related to the output voltage and output current of the first type of server 201. In some other examples, the management chip 231 can also control the output power of the first type of server 201 by controlling the output current of the first type of server 201, so that the output power of the first switching power supply 210 is the first sub-power threshold.

[0178] The power provided by the energy storage device 300 to each server 200 may be equal. At this time, the power provided by the second switching power supply 220 of each first-type server 201 may be equal.

[0179] In the following, a case is taken in which 14 servers 200 are arranged in the cabinet 100 of the computing device 1000, the power that can be loaded by the AC line is the first power threshold, the first power threshold is equal to 5KW, the power that can be provided by the energy storage device 300 is 2KW, and the actual power value of the computing device 1000 is 7KW. The power provided by the first switching power supply 210 of the first type of server 200 and the power provided by the second switching power supply 220 in the embodiment of the present application are exemplified.

[0180] Figure 8 is a power allocation diagram of multiple servers 200 in the computing device 1000 according to some embodiments.

[0181] See also Figure 8 , a plurality of servers 200 are arranged in the cabinet 100 of the computing device 1000, and the plurality of servers 200 are all first-type servers 201. At this time, the first switching power supply 210 of each server 200 can obtain power from the first AC line.

[0182] When the actual power value of the computing device 1000 is greater than the first power threshold, the device management unit 400 may control the power provided by the first switching power supply 210 of each server 200 to be equal, and the power provided by the second switching power supply 220 of each server 200 to be equal.

[0183] For example, the power that the AC line can provide is a first power threshold, the first power threshold is equal to 5KW, the power that the energy storage device 300 can provide is 2KW, and the actual power value of the computing device 1000 is 7KW. At this time, the power provided by the first AC line in the AC line is 5KW, and the power provided by the second AC line is 0W.

[0184] Among them, the first sub-power threshold can be 357W.

[0185] There are 14 servers 200 in the cabinet 100 of the computing device 1000, and the power of each server 200 is 500 W. The device management unit 400 can control the output power of the first switch power supply 210 to be 357 W through the management chip 231. At this time, the power obtained by the first switch power supply 210 of each server 200 from the first AC line can be 357 W. In addition, the device management unit 400 can control the output power of the second switch power supply 220 to be 143 W through the management chip 231, so that the power obtained by the second switch power supply 220 of each server 200 from the energy storage device 300 is 143 W.

[0186] Above, through Figure 8The case where the power provided by the first switching power supply 210 of the first type of server 201 is equal to the first power threshold is explained, and in some other embodiments, when the actual power value is greater than the first power threshold, the device management unit 400 can limit the power provided by the first switching power supply 210 of the first type of server 201 to be greater than or less than the first sub-power threshold P2 through the management chip 231 of the first type of server 201. Correspondingly, the device management unit 400 can limit the power obtained by the second switching power supply 220 of the first type of server 201 from the energy storage device 300 to be less than or greater than the difference between the power P1 of the first type of server 201 and the first sub-power threshold P2 through the management chip 231 of the first type of server 201.

[0187] Next, the power provided by the first switching power supply 210 and the second switching power supply 220 of the second type server 202 is described. In this embodiment, when the actual power value is greater than the first power threshold, the second switching power supply 220 of the second type server 202 can draw power from the energy storage device 300, and draw power from the second AC line through the power conversion device 500. At this time, the power provided by the second switching power supply 220 of the second type server 202 is equal to the power P1 of the second type server 202. At this time, the power provided by the first switching power supply 210 is 0W. Among them, the power provided by the power conversion device 500 to the second switching power supply 220 of the second type server 202 is the first sub-power threshold P2, and the power provided by the energy storage device 300 to the second switching power supply 220 of the second type server 202 is the difference between the power P1 of the second type server 202 and the first sub-power threshold P2, that is, P1-P2.

[0188] In some embodiments, the device management unit 400 can also limit the power obtained by the second switching power supply 220 of the second type of server 202 from the second AC line through the power conversion device 500 through the management chip 231 of the second type of server 202 to be greater than or less than the first sub-power threshold P2. Correspondingly, the device management unit 400 can also limit the power obtained by the second switching power supply 220 of the second type of server 202 from the energy storage device 300 through the management chip 231 of the second type of server 202 to be greater than or less than the difference between the power P1 of the second type of server 202 and the first sub-power threshold P2.

[0189] The power provided by the energy storage device 300 to each second-category server 200 may be equal and equal to the power provided by the second switching power supply 220 of the first-category server 200 .

[0190] The following takes the example that the power that the AC line can load is equal to the first power threshold, the first power threshold is equal to 5KW, the power that the energy storage device 300 can provide is 2KW, and the actual power value of the computing device 1000 is 7KW, as an example to illustrate the power provided by the first switching power supply 210 of the first type of server 200 and the power provided by the second switching power supply 220 in the embodiment of the present application.

[0191] Fig. 9 is another power allocation diagram of multiple servers 200 in the computing device 1000 according to some embodiments.

[0192] See also Fig. 9 A plurality of servers 200 are arranged in the cabinet 100 of the computing device 1000 , wherein some of the servers 200 are first-type servers 201 , and other servers 200 are second-type servers 202 .

[0193] When the actual power value of the computing device 1000 is greater than the first power threshold, the device management unit 400 can control the power provided by the first switching power supply 210 of each first-class server 201 to be equal, and control the power provided by the second switching power supply 220 of each first-class server 201 to be equal through the management chip 231.

[0194] The power of each second-category server 202 may be equal.

[0195] For example, 14 servers 200 are arranged in the cabinet 100 of the computing device 1000, wherein the 14 servers include one second-class server 202, and the rest are first-class servers 201. The first power threshold that can be provided by the AC line is equal to 5KW, the power that can be provided by the energy storage device 300 is 2KW, and the actual power value of the computing device 1000 is 7KW. At this time, the first sub-power threshold can be 357W.

[0196] Among them, the device management unit 400 can control the output power of the first switch power supply 210 of the first type server 201 to 357W through the management chip 231 of the first type server 201, so that the power obtained by the first switch power supply 210 of the first type server 201 from the first AC line is 357W. The power of the first type server 201 is 500W, and the power provided by the second switch power supply 220 of the first type server 201 is 143W. At this time, the power obtained by the first type server 201 from the energy storage device 300 is 143W.

[0197] The power provided by the first switching power supply 210 of the second type server 202 is 0W. At this time, the device management unit 400 can also control the second switching power supply 220 of the second type server 202 to simultaneously draw power from the power conversion device 500 and the energy storage device 300, wherein the power provided by the power conversion device 500 to the second switching power supply 220 is 357W, and the power provided by the energy storage device 300 to the second switching power supply 220 is 143W. At this time, the power provided by the second AC line and the energy storage device 300 to the second type server 202 is 500W.

[0198] At this time, the power provided by the first AC line is 4641 W, and the power provided by the second AC line is 357 W, so the power provided by the AC line is 5 KW. The power provided by the energy storage device 300 is 2 KW.

[0199] In addition, if the 14 servers 200 include two second-type servers 202, and the power of each second-type server 200 is 500W, the energy storage device 300 can provide 143W of power to each second-type server 202, and therefore, the power provided by the second AC line to the second switching power supply 220 of each second-type server 202 through the power conversion device 500 is 357W, and therefore, the total power provided by the second AC line is 714W. The power provided by the first AC line is 4286W.

[0200] exist Figure 8 and Fig. 9 In the example provided, the power of each server 200 is equal, while in some other examples, the power of each server 200 may be different.

[0201] In addition, the power provided by the first switch power supply 210 of each first type server 201 may be different, the power provided by the second switch power supply 220 of each first type server 201 may be different, and the power provided by the second switch power supply 220 of each second type server 202 may also be different.

[0202] Next, an exemplary description is given of the power provided by the first switching power supply 210 and the second switching power supply 220 of each server 200 when the power of some servers 200 is unequal.

[0203] Fig.10 is yet another power allocation diagram of the plurality of servers 200 in the computing device 1000 according to some embodiments.

[0204] See also Fig.10, the multiple servers 200 are all first-type servers 201. When the actual power value of the computing device 1000 is greater than the first power threshold, the power provided by the first switch power supplies 210 of some servers 200 may be equal, while the power provided by the first switch power supplies 210 of another part of the servers 200 may be unequal.

[0205] In addition, when the actual power value of the computing device 1000 is greater than the first power threshold, the device management unit 400 can determine the power provided by the energy storage device 300 according to the actual power value of the computing device 1000 and the first power threshold, and determine the second sub-power threshold according to the power provided by the energy storage device 300, wherein the product of the second sub-power threshold and the number of servers 200 is equal to the power provided by the energy storage device 300. The second sub-power threshold corresponding to each server 200 can be equal, and at this time, the power provided by the energy storage device 300 to each server 200 is equal, such as Fig.10 As shown, the power obtained by the second switching power supply 220 from the energy storage device 300 is 143W.

[0206] The device management unit 400 can control the output power of the first switching power supply 210 of the first type of server 201 to be equal to the difference between the power of the first type of server 201 and the second sub-power threshold through the management chip 231 of the first type of server 201. At this time, the power obtained by the first switching power supply 210 from the first AC line is the difference between the power of the first type of server 201 and the second sub-power threshold.

[0207] For example, among the 14 servers 200, all the 14 servers 200 are first-class servers 201, wherein the powers of the five first-class servers 201 are 643 W, 543 W, 753 W, 843 W and 443 W respectively. The device management unit 400 can control the first switching power supplies 210 of the five first-class servers 201 to provide powers of 500 W, 400 W, 600 W, 700 W and 300 W respectively. Therefore, the five first-class servers 201 each have a power shortage of 143 W. At this time, the second switching power supplies 220 of the five servers 200 can obtain 143 W of power from the energy storage device 300.

[0208] The output power of the first switch power supply 210 of the remaining first-category servers 201 may be 277 W. The power provided by the second switch power supply 220 of each first-category server 201 is 143 W.

[0209] Figures 8 to 10The power provided by the first switching power supply 210 and the second switching power supply 220 of the server 200 when the actual power value is greater than the first power threshold is described. Next, the power provided by the first switching power supply 210 and the second switching power supply 220 of the server 200 when the actual power value is less than the first power threshold is exemplified.

[0210] Fig.11 2 is a power allocation diagram of the first type of server 201 and the second type of server 202 in the computing device 1000 when the actual power value is less than or equal to the first power threshold. Fig.11 In the figure, the “×” on the line between the first switch power supply 210 of the second type server 202 and the load 230 indicates that the first switch power supply 210 of the second type server 202 cannot supply power to the load 230 of the second type server 202 .

[0211] See also Fig.11 , when the actual power value is less than or equal to the first power threshold, the power provided by the first switch power supply 210 of the first type of server 201 is equal to the power P1 of the first type of server 201, and the power provided by the second switch power supply 220 is 0W. At this time, the power (P1) of the first type of server 201 can be greater than, equal to, or less than the first sub-power threshold. Among them, the power P1 of the first type of server 201 is provided by the first AC line.

[0212] When the actual power value is less than or equal to the first power threshold, the power provided by the second switch power supply 220 of the second type server 202 is equal to the power (P1) of the second type server 202, and the power loaded by the first switch power supply 210 is 0 W. At this time, the power of the second type server 202 can be greater than, equal to, or less than the first sub-power threshold. The power of the second type server 202 is provided by the second AC line through the power conversion device 500.

[0213] Fig.12 FIG. 4 is another power allocation diagram of multiple servers 200 in the computing device 1000 according to some embodiments.

[0214] See also Fig.12 In some examples, when the actual power value of the computing device 1000 is less than the first power threshold, the power of some servers 200 may be greater than the first sub-power threshold P2 (i.e., 357W), while the power of some servers 200 may be less than the first sub-power threshold P2 (i.e., 357W), and the power of some servers 200 may be 0W. At this time, the power provided by the first AC line may be the sum of the powers of all servers 200, and the power provided by the energy storage device 300 may be 0W.

[0215] In some other examples, the power of all servers 200 may be equal.

[0216] Please refer again Fig.11 In this embodiment, the device management unit 400 is electrically connected to the energy storage device 300. The device management unit 400 is also used to control the power conversion device 500 to charge the energy storage device 300 when the actual power value of the computing device 1000 is less than the first power threshold.

[0217] When the actual power value of the computing device 1000 is less than the first power threshold, the power provided by the AC line does not reach the maximum AC power. Therefore, the power that the AC line can provide has a margin. At this time, the power conversion device 500 takes power from the second AC line and charges the energy storage device 300, which can ensure that the energy storage device 300 has sufficient capacity, and then the energy storage device 300 can load more power for the computing device 1000, thereby increasing the maximum power of the computing device 1000. In addition, when the actual power value of the computing device 1000 is less than the first power threshold, that is, when the energy storage device 300 does not supply power to multiple servers 200, the power conversion device 500 charges the energy storage device 300, thereby extending the service life of the energy storage device 300.

[0218] In some examples, the device management unit 400 is used to: when the actual power value of the computing device 1000 is less than the first power threshold, obtain the remaining capacity of the energy storage device 300, and when the remaining capacity of the energy storage device 300 is less than the full charge capacity of the energy storage device 300, control the power conversion device 500 to charge the energy storage device 300. The full charge capacity of the energy storage device 300 refers to the electric energy contained in the energy storage device 300 when it is fully charged. In other words, the maximum value of the remaining capacity of the energy storage device 300 is equal to the full charge capacity of the energy storage device 300.

[0219] In some examples, the device management unit 400 is further used to: when the actual power value is greater than the first power threshold, control the energy storage device 300 and the power conversion device 500 to jointly power the server 200. For example, the management unit 400 can control the output voltage of the energy storage device 300 to be the same or similar to the output voltage of the power conversion device 500. When the output voltage of the energy storage device 300 is similar to the output voltage of the power conversion device 500, the voltage difference between the output voltage of the energy storage device 300 and the output voltage of the power conversion device 500 is less than or equal to the preset value. As long as the voltage difference between the output voltage of the energy storage device 300 and the output voltage of the power conversion device 500 is less than or equal to the preset value, the energy storage device 300 and the power conversion device 500 can jointly power multiple loads 230.

[0220] At the same time, the management unit 400 can also limit the output power of the power conversion device 500 to the difference between the first power threshold and the power provided by the first AC line, that is, so that the power obtained by multiple servers 200 from the AC line is the first power threshold, and the power obtained from the energy storage device is the difference between the actual power value and the first power threshold.

[0221] For example, the management unit 400 may limit the output power of the power conversion device 500 by controlling the output voltage of the power conversion device 500 to be lower than the output voltage of the energy storage device 300, so as to limit the output power of the power conversion device 500. It is understandable that when the output voltage of the power conversion device 500 is adjusted to be lower than the output voltage of the energy storage device 300, both the energy storage device 300 and the power conversion device 500 need to be in a discharge state to ensure that the energy storage device 300 and the power conversion device 500 can jointly power the server 200. For example, the voltage difference between the output voltage of the energy storage device 300 and the power conversion device 500 is less than or equal to a preset threshold value. When the voltage difference between the output voltage of the energy storage device 300 and the power conversion device 500 is less than or equal to the preset threshold value, the power conversion device 500 and the energy storage device 300 can jointly power multiple loads and can limit the output power of the power conversion device 500.

[0222] Of course, the output power of the power conversion device 500 may be related to the output voltage and the output current of the power conversion device 500. In some other examples, the management unit 400 may also control the output power of the power conversion device 500 by controlling the output current of the power conversion device 500, so as to limit the output power of the power conversion device 500.

[0223] The device management unit 400 is also used to: when the actual power value is less than the first power threshold, control the power conversion device 500 to supply power to the server 200, and the energy storage device 300 does not supply power to the server 200. For example, the device management unit 400 can control the output voltage of the power conversion device 500 to be greater than the output voltage of the energy storage device 300, so that the power conversion device 500 is in a discharging state and the energy storage device 300 is in a non-discharging state. The device management unit 400 can also control the power conversion device 500 to charge the energy storage device 300.

[0224] Of course, when the actual power value is equal to the first power threshold, the equipment management unit 400 can control the energy storage device 300 to be in a state of neither charging nor discharging.

[0225] In this embodiment, the device management unit 400 is electrically connected to the energy storage device 300. The device management unit 400 is also used to obtain the remaining capacity of the energy storage device 300, adjust the capping power of the computing device 1000 according to the remaining capacity, and control the actual power value of the computing device 1000 to be less than or equal to the capping power.

[0226] Among them, when the remaining capacity of the energy storage device 300 is different, the power that the energy storage device 300 can load is different. The energy storage device 300 can be used together with the AC line to power multiple servers 200 in the computing device 1000. Therefore, when the remaining capacity of the energy storage device 300 is different, the maximum power that the computing device 1000 can reach is different.

[0227] The capped power of the computing device 1000 can limit the actual power value of the computing device 1000. After determining the capped power of the computing device 1000, the actual power value of the computing device 1000 will not exceed the capped power of the computing device 1000. If at a certain moment, the business of the computing device 1000 suddenly increases, causing the actual power value of the computing device 1000 to increase, the device management unit 400 can reduce the power of at least part of the devices in the computing device 1000, such as reducing the power of one or more servers 200, so as to reduce the actual power value of the computing device 1000, thereby making the actual power value of the computing device 1000 below the capped power of the computing device 1000.

[0228] In the embodiment of the present application, the remaining capacity of the energy storage device 300 is obtained by the device management unit 400, and the capped power of the computing device 1000 is adjusted according to the remaining capacity, so that the power of the computing device 1000 can be prevented from exceeding the sum of the powers that can be loaded by the AC line and the energy storage device 300. Since the power that can be loaded by the AC line is constant, it is possible to prevent the computing device 1000 from losing power due to insufficient remaining capacity of the energy storage device 300.

[0229] For example, the first power threshold is 5KW, that is, the maximum AC power Pac-max is 5KW. Assuming that the power that the energy storage device 300 can load is 1KW, and the actual power value of the computing device 1000 is 5.5KW, at this time, the power loaded by the AC line is 5KW, and the power loaded by the energy storage device 300 is 0.5KW. At this time, the energy storage device 300 can load the power difference between the actual power value of the computing device 1000 and the first power threshold. If at a certain moment, the capacity of the energy storage device 300 is reduced, and the power that can be loaded is only 0.3KW, while the actual power value of the computing device 1000 is still 5.5KW, at this time, the power that the AC line can load is 5KW, and the power that the energy storage device 300 needs to load is 0.5KW. However, since the remaining capacity of the energy storage device 300 can only load 0.3KW of power, which is less than 0.5KW, it may cause the computing device 1000 to lose power.

[0230] In the embodiment of the present application, the device management unit 400 can adjust the capped power of the computing device 1000 according to the remaining capacity of the energy storage device 300. Therefore, the capped power of the computing device 1000 can be modified to 5.3KW. At this time, the power that the energy storage device 300 needs to load is 0.3KW. Therefore, the energy storage device 300 can load the power difference between the actual power value of the computing device 1000 and the first power threshold. This can avoid the inability to load the power difference between the actual power value of the computing device 1000 and the first power threshold due to insufficient remaining capacity of the energy storage device 300, thereby avoiding power failure of the computing device 1000.

[0231] In some examples, the capped power of computing device 1000 may be adjusted by modifying the capped power of some or all of servers 200 in computing device 1000 .

[0232] The capped power of the server 200 may be less than, equal to, or less than the first sub-power threshold.

[0233] Please refer again Figure 6 In this embodiment, the computing device 1000 further includes a switch 700 . The switch 700 may be disposed in the cabinet 100 .

[0234] The first input terminal of the switch 700 may be electrically connected to a first AC line, so that the first AC line may supply power to the switch 700 .

[0235] The second input end of the switch 700 can be electrically connected to the output end of the energy storage device 300 and the output end of the power conversion device 500 , so that both the energy storage device 300 and the power conversion device 500 can supply power to the switch 700 .

[0236] For example, the switch 700 may include two switching power supplies, wherein an input end of one switching power supply may be electrically connected to a first AC line, and the input end of the switching power supply may serve as a first input end of the switch 700, and an input end of the other switching power supply may be electrically connected to a power conversion device 500 and an energy storage device 300, and the input end of the switching power supply may serve as a second input end of the switch 700.

[0237] For example, when the computing device 1000 also includes a power distribution unit 600, the two switching power supplies of the switch 700 can be electrically connected to the two power distribution units 600 respectively, so that the two switching power supplies of the switch 700 are electrically connected to the first AC line, the power conversion device 500 and the energy storage device 300 respectively.

[0238] The switch 700 includes a first communication interface 710 and a plurality of second communication interfaces 720, wherein the first communication interface 710 is connected to the device management unit 400, the first communication interface 710 is connected to a plurality of second communication interfaces 720, and each second communication interface 720 is connected to the management chip 231 of the corresponding server 200. Therefore, the device management unit 400 can communicate with the management chip 231 of the server 200 corresponding to the second communication interface 720 through the first communication interface 710, and then the device management unit 400 can send a management signal to the management chip 231, so as to control the server 200 through the management chip 231.

[0239] For example, the first communication interface 710 and the second communication interface 720 can both be network ports, wherein the first communication interface 710 can be connected to the device management unit 400 via a network cable, and the second communication interface 720 can be connected to the management chip 231 of the corresponding server 200 via a network cable.

[0240] In some examples, the device management unit 400 is also used to: when the actual power value is less than or equal to the first power threshold, control multiple servers 200 and switches 700 to draw power from the AC line, so that the AC line supplies power to the multiple servers 200 and switches 700; when the actual power value is greater than the first power threshold, control multiple servers 200 and switches 700 to draw power from the AC line and the energy storage device 300, so that the AC line and the energy storage device jointly supply power to the multiple servers 200 and switches 700.

[0241] In some of the above embodiments, the power supply method of the computing device 1000 is introduced. Next, the device management unit 400 is introduced.

[0242] In some examples, the device management unit 400 may include a control chip with management functions. For example, the device management unit 400 may include a control chip with management functions such as a BMC, an FPGA (Field-Programmable Gate Array), or a microcontroller unit.

The power acquisition module 410 is connected to the management chips 231 of the multiple servers 200, and the processing module 420 is connected to the power acquisition module 410 and the management chips 231 of the multiple servers 200.

[0245] The power acquisition module 410 is used to acquire the power of multiple servers 200, and determine the actual power value of the computing device 1000 according to the power of multiple servers 200. For example, the management chip 231 can determine the power of the server 200 where the management chip 231 is located according to the sum of the input power of the first switching power supply 210 and the input power of the second switching power supply 220. The management chip 231 can send the power of the server 200 to the power acquisition module 410.

[0246] The processing module 420 is used to: when the actual power value is less than or equal to the first power threshold, control the multiple servers 200 to draw power from the AC line, so that the sum of the AC power obtained by the multiple servers 200 from the AC line is the actual power value; when the actual power value is greater than the first power threshold, control the multiple servers 200 to draw power from the AC line and the energy storage device 300, so that the AC line and the energy storage device 300 jointly power the multiple servers 200, so that the sum of the AC power obtained by the multiple servers 200 from the AC line is the first power threshold, and the sum of the DC power of the multiple servers 200 is the power difference between the actual power value and the first power threshold.

[0247] In this embodiment, when the actual power value is less than or equal to the first power threshold, the management chip 231 of the first type of server 201 can control the first switching power supply 210 to draw power from the first AC line according to the first management signal, so that the first switching power supply 210 supplies power to multiple loads 230 of the first type of server 201; and / or, the processing module 420 generates a second management signal and sends it to the management chip 231 of the second type of server 202.

[0248] When the actual power value is greater than the first power threshold, the processing module 420 generates a third management signal and sends it to the management chip 231 of the first type of server 201. The management chip 231 of the first type of server 201 can control the first switching power supply 210 of the first type of server 201 to draw power from the first AC line and control the second switching power supply 220 of the first type of server 201 to draw power from the energy storage device 300 according to the third management signal, so that the first switching power supply 210 and the second switching power supply 220 of the first type of server 201 jointly power multiple loads 230; and / or, the processing module 420 generates a fourth management signal and sends it to the management chip 231 of the second type of server 202. The management chip 231 of the second type of server 202 can control the second switching power supply 220 of the second type of server 202 to draw power from the second AC line through the power conversion device 500 according to the fourth management signal, and control the second switching power supply 220 of the second type of server 202 to also draw power from the energy storage device 300, so that the second switching power supply 220 of the second type of server 202 can power multiple loads 230.

[0250] Based on this, an embodiment of the present application provides a computing device 1000, which may include an energy storage device 300, multiple servers 200, and a device management unit 400.
