[0073] At present, the liquid-cooled servers in the liquid-cooled data center are mainly transformed from air-cooled servers, and the power supply mainly adopts a distributed power supply mode, with each server equipped with a 1+1 redundant CRPS power supply. For the entire TANK power supply, this power supply mode has too high power redundancy, resulting in a serious waste of resources. How to achieve centralized and refined management of immersion liquid-cooled TANK power supply, reduce data center design costs, and reduce the waste of electric energy resources is an urgent problem to be solved.

[0074] The present application provides a power supply assembly 100 .

[0075] See also Figure 1In one embodiment of the present application, the power supply assembly 100 is applied to an immersion liquid-cooled TANK power supply device, the immersion liquid-cooled TANK power supply device includes a plurality of servers immersed in a cooling liquid, and the power supply assembly 100 includes:

[0076] multiple power supplies 120;

[0077] A power control board 110, one end of a power output interface 113 of the power control board 110 is electrically connected to the power output ends of the multiple power supplies 120; the other end of the power output interface 113 of the power control board 110 is electrically connected to the power ends of the multiple servers; the multiple first control ends of the power control board 110 are electrically connected to the multiple power supplies 120 in a one-to-one correspondence;

[0078] The power control board 110 is used to control the operation of multiple power supplies 120 to supply power to the operating servers. The power control board 110 is also used to obtain the power demand of the server and control the operation of a corresponding number of power supplies to adapt to the power supply changes of the server.

[0079] It should be noted that the power provided by the multiple power supplies 120 is output to the power control board 110, and then output to multiple servers after being uniformly deployed and managed by the power control board 110. Among them, the switch of each power supply can be controlled, and the power supply can be dynamically controlled to be turned on / off according to the power demand of the server in the TANK, reducing unnecessary power supply operation loss, and greatly reducing the waste of power while ensuring power supply.

[0080] It should be noted that the power supply changes of the server include the power supply changes caused by the change in the number of servers and the power supply changes caused by the change in the operating power of a single server. In this embodiment, the power control board 110 can detect the power demand of the server and control the corresponding number of power supplies to work to adapt to the power supply changes of the server. For example, when the number of servers increases or the operating power of a single server increases, the power demand of the server increases, and exceeds the power supply power of the current number of power supplies, then the number of working power supplies is controlled to increase to increase the power supply to adapt to the power supply changes of the server. On the contrary, when the number of servers decreases or the operating power of a single server decreases, the power demand of the server decreases, and the excess power exceeds the rated output power of a single power supply, then the number of working power supplies can be controlled to decrease to reduce the power supply to adapt to the power supply changes of the server.

[0081] It should be noted that in an exemplary TANK power supply method, the power supply still uses an air-cooled CRPS power supply, and each server is equipped with a standard 1+1 redundant power supply. When immersed in liquid cooling, the fan of the CRPS power supply is removed, and the internal software code is updated to turn off the alarm for removing the fan. The entire server is placed upside down in the TANK, and the CRPS power supply is in the upper part of the TANK box. It is connected to 220V AC or 240V DC to start working, and each server has a 50% power redundancy. However, this TANK power supply method has the problems of increased costs and waste of electric energy due to excessive redundancy of the power supply, as well as the problem of low reliability due to the simple modification of the air-cooled power supply for use in an immersed liquid cooling environment.

[0082] In this embodiment, the power supply can be a CRPS power supply. It should be noted that the +12V power supply output by the CRPS power supply can be uniformly connected to the positive pole of the input end of the power output interface 113 of the power control board 110 through PCB routing and power shape, and the GND end of the CRPS power supply can also be uniformly connected to the negative pole of the input end of the power output interface 113 of the power control board 110. In this way, the CRPS power supply can output power to the input end of the power output interface 113 of the power control board 110, and then output it to the server through the output end of the power output interface 113. The air-cooled CRPS power supply can still be used, which is compatible with the original air-cooled server. Among them, the power supply is not immersed in the coolant to improve the reliability of the power supply.

[0083] In this embodiment, the number of servers may be N. The number of CRPS power supplies may be N+n, and the rated output power of each CRPS power supply is greater than or equal to the power demand of each server. Among them, N CRPS power supplies are used to provide non-redundant power supplies to N servers, and n CRPS power supplies are used to provide redundant backup power supplies to N servers. Among them, N and n are positive integers greater than 0. Assuming that N is 20 and n is 2, the number of CRPS power supplies in this embodiment is 20+2. Compared with the number of CRPS power supplies of 20+20 in the TANK power supply mode, the design cost of the data center is reduced, the problem of excessive redundancy of the distributed power supply mode of TANK is solved, the waste of electric energy resources is reduced, and the design cost is reduced. It can be understood that the value of n can be set according to the specific situation, and there is no restriction here.

[0084] It should be noted that in another exemplary TANK power supply method, each power rack Powershelf of the immersed liquid-cooled TANK corresponds to a management board, and the main management board can be identified according to the ID of each management board in the immersed liquid-cooled TANK. Then, the main management board establishes a network connection with each other slave management board through a preset fixed IP. Then, through the network connection, the PSU management information in the corresponding Powershelf is collected from each other slave management board. Further, the main management board can analyze, summarize and save the collected PSU management information in each Powershelf in the immersed liquid-cooled TANK in combination with its own power management information, so as to realize the centralized monitoring and management of the power information of the immersed liquid-cooled TANK. However, this TANK power supply method realizes the information monitoring of the power supply Powershelf through the network management of each management board, and there is a risk of network disconnection in the network connection. Moreover, this method only monitors the power supply to facilitate the location of the faulty power supply, but does not effectively manage the output power. Compared with the exemplary TANK power supply method, this embodiment is directly connected and managed through hardware circuits. The power control board 110 can directly obtain the power requirements of the server and control the corresponding number of power supplies to adapt to the power supply changes of the server. There is no risk of network disconnection, and the reliability is stronger. In addition, the output power is effectively managed to reduce power waste.

[0085] Thus, compared with the prior art, this embodiment centrally manages multiple power supplies 120 through the power control board 110, thereby solving the problem of high redundancy of the distributed power supply mode of the existing immersed liquid-cooled TANK, reducing power waste, and reducing design costs. In addition, a CRPS power supply can be used, which does not need to be immersed in coolant, is compatible with the original air-cooled server, and improves the reliability of the CRPS power supply. Through the effective management of the output power, the optimization of the existing TANK power supply is achieved. Through direct connection management by hardware circuits, there is no risk of network disconnection, and the reliability is stronger.

[0086] In the present application, the electric energy provided by multiple power supplies 120 is output to the power control board 110, uniformly deployed and managed by the power control board 110, and then output to multiple servers. Among them, the switch of each power supply can be controlled, and the power supply can be dynamically controlled to be turned on / off according to the power demand of the server in the TANK to adapt to the power supply changes of the server and reduce unnecessary power supply operation losses. In this way, compared with the prior art, the present application centrally manages multiple power supplies 120 through the power control board 110, solves the problem of high redundancy of the distributed power supply method of the existing immersion liquid-cooled TANK, reduces power waste, and reduces design costs. Through the effective management of the output electric energy, the optimization of the existing TANK power supply is achieved. Through direct connection management by hardware circuit, there is no risk of network disconnection, and the reliability of power supply is stronger.

[0087] See also Figure 2 In one embodiment of the present application, the power control board 110 includes:

[0088] Circuit boards;

[0089] The power detection module 112 is arranged on the circuit board. The detection end of the power detection module 112 is electrically connected to the power output interface 113 of the power control board 110 . The power detection module 112 is used to detect the actual output power of the power output interface 113 of the power control board 110 .

[0090] The main controller 111 is arranged on the circuit board, and the first signal end of the main controller 111 is electrically connected to the other end of the signal output end of the power detection module 112; the multiple second signal ends of the main controller 111 are electrically connected to the multiple servers in a one-to-one correspondence; the multiple first control ends of the power control board 110 are electrically connected to the multiple power supplies 120 in a one-to-one correspondence; the multiple second control ends of the power control board 110 are electrically connected to the multiple servers in a one-to-one correspondence; the multiple second signal ends of the main controller 111 are used to obtain or receive the whole machine operating power of the multiple servers.

[0091] The main controller 111 is used to determine the power demand of the server according to the actual output power and / or the whole machine operating power, and control the corresponding number of power supplies to work in multiple modes to adapt to the power supply changes of the server.

[0092] It should be noted that the main controller 111 may be a CPLD (Complex Programmable Logic Device), which can process multiple logic signals simultaneously to improve response speed and efficiency.

[0093] It should be noted that the power detection module 112 can detect the total power supply of the power output interface 113, including information such as voltage, current and power, and transmit the detected actual output power information to the main controller 111 through I2C. The main controller 111 can determine the power demand of the server based on the actual output power obtained. For example, when the actual output power increases to the next level threshold, it can be determined that the server has reached the next level of power demand; or when it decreases to the previous level threshold, it can be determined that the server has reached the previous level of power demand. The main controller 111 can also calculate the total operating power of multiple servers based on the obtained whole machine operating power of multiple servers, and then determine the power demand of the server. Generally speaking, the whole machine operating power of multiple servers can directly reflect the power demand of the server. It should be noted that if the server only processes a small number of tasks during operation, the actual output power may be lower than the total operating power; if the server processes a large amount of data or runs high-performance applications, the actual output power may exceed the total operating power. In this embodiment, the main controller 111 can also determine the power demand of the server according to the larger of the actual output power and the total operating power, which can ensure that the server can obtain sufficient power under any circumstances, thereby avoiding failure or performance degradation caused by insufficient power. Then, the CRPS power supply can be controlled to be turned on and off according to the power demand, and a corresponding number of CRPS power supplies are selected to work to provide power, and other CRPS power supplies are turned off.

[0094] It should be noted that the main controller 111 can obtain the working status of the server, and in response to the working status of the server, control to enter the corresponding mode to adapt to the power supply change of the server. Among them, the main controller 111 can be connected to the host computer, and the working status of the server can be triggered by the user in the host computer. The working status of the server can also be obtained by directly detecting the working parameters of the server, which is not limited here. Among them, the working status of the server can include an initialization startup state, a stable operation state, a newly added server power-on state, and a server overload state, which can correspond to entering a power-on power mode, a real-time operation power mode, a newly added server power-on mode, and a power protection mode.

[0095] In one embodiment, the main controller 111 has a power-on mode, a real-time operation mode, and a new server power-on mode:

[0096] In the power-on mode, the main controller 111 is specifically used to control the operation of all power supplies. In this mode, the operation of all power supplies can ensure that sufficient power is provided to start all server startup operations.

[0097] In the real-time power supply mode, the main controller 111 is specifically used to control a corresponding number of power supplies to work according to power requirements to adapt to power supply changes of the server.

[0098] In the newly added server startup mode, the main controller 111 is specifically used to obtain the number of newly added servers and control the corresponding number of power supplies according to the number of newly added servers. It should be noted that in the newly added server startup mode, the number of newly added servers can reflect the power demand of the servers.

[0099] In the power protection mode, the main controller 111 is specifically used to control the corresponding number of servers to work so that the power demand of the working servers is less than the output power provided by the total number of power supplies. In this mode, the power supply can be prevented from being in an overload state and the service life of the power supply can be extended.

[0100] See also Figure 3 In one embodiment of the present application, the power supply assembly 100 further includes a power connector; a plurality of male connectors of the power connector are electrically connected to a plurality of power supplies in a one-to-one correspondence, and a female connector of the power connector is electrically connected to a power control board 110;

[0101] The multiple male heads of the power connector each have a power control terminal, a first signal detection terminal and a second signal detection terminal;

[0102] The power control board 110 is used to control the level state of the power control terminal to control the operation / stop of the corresponding power supply;

[0103] The power control board 110 is further used to read the power failure information of the corresponding power supply based on the first signal detection end, and control the corresponding power supply to stop working when the corresponding power supply failure is determined according to the power failure information, and control another non-working power supply to work;

[0104] The power control board 110 is also used to read the level state of the second signal detection terminal, and control the corresponding power supply to stop working when it is determined that the corresponding power supply is abnormal according to the level state of the second signal detection terminal, and control another non-working power supply to work.

[0105] It should be noted that the CRPS power supply can be connected to the main controller 111 through the power connector at the output end, and the main controller 111 can number the male part of the power connector, such as C1, C2 to CM, to correspond to the power supplies C1, C2 to CM connected to the male connector. The CRPS power supply as a whole can adopt N+2 redundancy, that is, M=N+2, where the number N is determined according to the maximum power of the server of the TANK. For example, the maximum power requirement of a 42U TANK is 40KW, and the CRPS power supply is selected as 2000W, then N=20, M=22, that is, the number of CRPS power supplies designed is 22, and the number M of CRPS power supplies will also change according to the specific power requirements and the selected CRPS power supply power.

[0106] It should be noted that the first signal detection terminal (i.e., PMBUSSDA terminal and PMBUS SCL terminal), the power control terminal (i.e., PSON terminal), and the second signal detection terminal (PWOK terminal) corresponding to the multiple CRPS power supplies can be connected to the main controller 111 through PCB routing. The main controller 111 can directly read the register information inside the CRPS power supply through the PMBUS SDA terminal and the PMBUS SCL terminal, and can obtain the power failure information of the CRPS power supply. The CRPS power supply can be turned on and off through the PSON terminal. When the PSON signal is pulled high, the CRPS power supply is turned off and +12V is not output. When the PSON signal is pulled low, the CRPS power supply is turned on and outputs +12V power. The CPLD controls the +12V output of the CRPS power supply by controlling the high and low voltage of the signal output to PSON. When the CRPS power supply output is normal, the PWOK signal will be pulled high. When the CRPS power supply does not have a +12V output, the PWOK signal will be pulled low. It can be judged whether the CRPS power supply outputs 12V power normally based on the high and low output of the PWOK signal.

[0107] It should be noted that the power-on process is as follows: the main controller 111 outputs a first control signal to pull down the PSON signal of the power supply to be turned on, starts the CRPS power supply, and detects the PWOK signal of the power supply. If the PWOK signal is not pulled high, the output fault of the power supply is output, and the same operation is performed to turn on the next unturned power supply. When the number of faulty power supplies plus the number of turned-on power supplies exceeds the total number of power supplies, all power supplies are turned off and the fault is reported. At this time, the operation and maintenance personnel will inspect the power supply module.

[0108] The present application also proposes an immersion-type liquid-cooled TANK power supply device, which includes a plurality of servers immersed in cooling liquid and a power supply component 100. The specific structure of the power supply component 100 refers to the above-mentioned embodiment. Since the immersion-type liquid-cooled TANK power supply device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0109] In one embodiment of the present application, the server includes:

[0110] A first controller is used to detect the whole machine operating power of the server;

[0111] A second controller, a first signal end of the second controller is electrically connected to the first controller, a second signal end of the second controller is electrically connected to a second signal end of the power control board 110 of the power supply component 100, and a controlled end of the second controller is electrically connected to a second control end of the power control board 110 of the power supply component 100; the second controller is used to obtain the overall operating power of the server and send it to the power control board 110; the second controller is also used to control the operation / stop operation of the server according to a second control signal output by the power control board 110.

[0112] It should be noted that each server in the TANK may include a first controller, such as a BMC (Baseboard Management Controller) chip, and a second controller, such as a CPLD (Complex Programmable Logic Device) chip. The BMC chip can monitor the overall operating power consumption of the server, and the CPLD chip can read the overall operating power consumption of the server detected by the BMC chip through the I2C protocol. At the same time, the CPLD chip can also control the server shutdown.

[0113] It should be noted that the main controller 111 can read the information of the CPLD chip of each server, mainly the overall operating power consumption of the server, that is, the power required by the server, and can send a second control signal to control the CPLD chip of the server to shut down the server.

[0114] It should be noted that the main controller 111 can number the CPLD chips of the servers in the TANK, starting from the first server on the left side of the TANK, specifically S1, S2 to SN, and assign a unique address to the CPLD chip of the server, so that the main controller 111 can identify the CPLD chip of each corresponding server. The control board reads the power consumption of each server as Ps1, Ps2 to Psn.

[0115] See also Figure 1 In one embodiment of the present application, the submerged liquid-cooled TANK power supply device further includes:

[0116] A liquid cooling box body, wherein the liquid cooling box body is formed with two accommodating spaces isolated from each other;

[0117] Among them, one accommodating space is an inner tank, which is used to place coolant and multiple servers;

[0118] Another accommodating space is used to place multiple power supplies 120 and a power control board 110;

[0119] A power output connection cable is disposed in another accommodating space, and one end of the power output connection cable is used to electrically connect to the power control board 110;

[0120] A power supply rotary head is arranged on the bottom wall of one side of the inner container close to the power supply control board 110, and the power supply rotary head is used to electrically connect the other end of the power supply output connection cable;

[0121] The power copper bar is arranged at the bottom of the inner tank, and is used to realize the electrical connection between the power rotor and the server.

[0122] In this embodiment, the overall TANK structure is a box body on the outside, and the inside mainly includes two spaces. The space near the front is the TANK inner tank, which is mainly used to place IT equipment such as servers and coolant, and the server can be inserted vertically in the inner tank. The other accommodating space is used to place multiple power supplies 120 and a power control board 110. The other accommodating space is not directly connected to the inner tank of the TANK, that is, the power supply is not immersed in the coolant, which reduces the failure rate of the power supply.

[0123] It should be noted that the power output connection cable is arranged in another accommodation space, the power supply head is arranged on the bottom wall of one side of the inner tank close to the power control board 110, and the power supply copper bar is arranged at the bottom of the inner tank. Among them, the power supply head can be designed to be embedded in the side wall of the TANK inner tank and be strictly sealed to ensure that the coolant in the inner tank will not flow into the accommodation space where the power supply is located. The accommodation space where the power supply is located is responsible for the control and management of the centralized power supply of the power supply, including multiple power supplies 120, power sockets, power control boards 110 and power output connection cables.

[0124] It should be noted that when the power control board 110 is supplying power, the power is output through the power output connection cable, and then input into the power copper bar in the inner tank through the power rotor. The server can obtain power through its own power input fixture connected to the power copper bar to start working.

[0125] The present application also proposes a power management method, which is applied to an immersion liquid-cooled TANK power supply device, wherein the immersion liquid-cooled TANK power supply device includes a plurality of power supplies 120 and a plurality of servers immersed in cooling liquid; the power management method includes:

[0126] Acquire the working status of the server, and execute a corresponding power supply strategy in response to the working status of the server;

[0127] Under a corresponding power supply strategy, control a corresponding number of power supplies and / or a corresponding number of servers to work;

[0128] Among them, the server's working status includes initial startup status, stable operation status, newly added server startup status and server overload status; the power supply strategy includes startup power supply strategy, real-time operation power supply strategy, newly added server startup strategy and power protection strategy.

[0129] The step of executing a corresponding power supply strategy in response to the working state of the server comprises:

[0130] In response to the server being in an initialization startup state, executing a power-on power policy;

[0131] In response to the server being in a stable operating state, executing a real-time operating power policy;

[0132] In response to the server being in a newly added server startup state, executing a newly added server startup policy;

[0133] In response to the server being in a server overload state, a power protection strategy is executed.

[0134] It should be noted that when the entire TANK power supply device is turned on, the server is in the initialization startup state. When the operation of various parameters of the server is relatively stable, such as the overall power consumption of the server is relatively stable and fluctuates within a preset range, the server is in a stable operation state. When a new server is turned on, the server is in the newly added server power-on state. When the server is overloaded, for example, when the power demand of the server is greater than or equal to the output power of all the power supplies, the server is in a server overload state. In this way, this embodiment can execute corresponding power supply strategies according to different working states of the server, and can optimize the power management of the TANK power supply device. In this embodiment, centralized management of power supply in the TANK can be achieved, reducing the risk of CRPS power supply being immersed in coolant and improving the reliability of the power supply. At the same time, all CRPS power supplies of the TANK are uniformly deployed and managed, and the switch of each power supply can be controlled. The CRPS can be dynamically controlled to be turned on / off according to the power demand of the server in the TANK, reducing unnecessary power supply operation losses, and greatly reducing the waste of electric energy while ensuring power supply. It should be noted that when a server is shut down, a real-time power supply strategy can also be executed to ensure the stable operation of the server in the TANK.

[0135] In one embodiment of the present application, the power supply strategy specifically includes: controlling the operation of all power supplies to prevent the system from shutting down due to excessive power consumption of the newly started server. If all the working servers are converted from the initial startup state to the stable operation state, the real-time operation power supply strategy is executed.

[0136] It should be noted that when all servers are about to enter the initialization startup state, the main controller 111 can output the PSON signal and pull it all down, and all CRPS power supplies start working and have power output to prevent the system from crashing due to excessive power consumption of the newly started servers. The main controller 111 can communicate with each connected CRPS power supply through the Pmbus protocol and assign an address to each CRPS power supply. For example, the CRPS power supply address of C1 is assigned "00001", and the CRPS address of C2 is assigned "00010", and so on. Each CRPS power supply has an independent address. Until the working servers are converted from the initialization startup state to the stable operation state, the real-time operation power supply strategy is executed to adapt to the power supply changes of all servers during stable operation.

[0137] In one embodiment of the present application, please refer to Figure 4 and Figure 5 , the real-time power strategy includes:

[0138] Obtain the actual output power P1 of multiple power supplies;

[0139] Obtain the whole machine operating power of each server, and calculate the total operating power P2 of multiple servers based on the whole machine operating power;

[0140] If the actual output power P1 is greater than or equal to the total operating power P2, the actual output power P1 is used as the power requirement P0 of the server;

[0141] If the actual output power P1 is less than the total operating power P2, the total operating power P2 is used as the power requirement P0 of the server;

[0142] According to the power demand P0 of the server and the power margin Pt, the corresponding number of power supplies are controlled to work; wherein the power margin Pt indicates the reserved power required for the power supply to turn on / off.

[0143] It should be noted that if the server only processes a small number of tasks during operation, the actual output power P1 may be lower than the total operating power P2; if the server processes a large amount of data or runs a high-performance application, the actual output power P1 may exceed the total operating power P2. In this embodiment, the larger of the actual output power P1 and the total operating power P2 can be used as the power requirement of the server, which can ensure that the server can obtain sufficient power in any case, thereby avoiding failures or performance degradation caused by insufficient power.

[0144] It should be noted that the opening and closing of the CRPS power supply requires a certain power margin Pt to be reserved, the rated output power of a single CRPS power supply is Ps, and the power demand of the server is P0. When the server is in a stable working state, if the load on the server side increases, the power demand of the server increases, and more CRPS power supplies need to be controlled to be turned on to provide sufficient power. Similarly, if the power demand of the server decreases, the most recently turned on CRPS power supplies are turned off in turn to prevent the waste of power energy. In this way, this embodiment can turn on a corresponding number of power supplies to provide power according to the actual power demand of the server to avoid wasting power.

[0145] In an embodiment of the present application, the newly added server startup strategy specifically includes:

[0146] Get the number of newly added servers;

[0147] According to the number of newly added servers, the corresponding number of power supplies are controlled to work; wherein, if the newly added server is converted from the initialization startup state to the stable operation state, the real-time operation power supply strategy is executed.

[0148] In this embodiment, the number of newly added servers can reflect the power demand of the newly added servers when they are turned on. The rated output power of each CRPS power supply is greater than or equal to the whole machine operating power of each server. Therefore, turning on a newly added CRPS power supply can ensure the power supply of a server during the startup process. If the newly added server is converted from the initial startup state to the stable operation state, the real-time operation power supply strategy is executed to adapt to the power supply changes of the server during stable operation.

[0149] It should be noted that, in a stable working state, the power supply is managed according to the real-time power supply strategy. When a server is shut down, the main controller 111 also adjusts the power supply according to the power change. When the main controller 111 detects a power-on request of a server, a new CRPS power supply is turned on to ensure the power supply during the server startup process. After the server completes the initial startup, the real-time power supply strategy is entered to adjust the power supply in real time. Similarly, when the power-on requests of multiple servers are detected at the same time, multiple CRPS power supplies are turned on.

[0150] See also Figure 6 In one embodiment of the present application, the power protection strategy specifically includes:

[0151] Get the power requirement P0 of the server;

[0152] If the power demand P0 of the server is greater than or equal to the output power Pmax of all power supplies, the number of working servers is gradually reduced, and the power demand P0 of the remaining working servers is recalculated each time the number of working servers changes;

[0153] If the power demand P0 of the remaining servers is less than the output power Pmax of all power supplies, the power protection strategy is exited.

[0154] It should be noted that the output power Pmax of all the power supplies is the product of the rated output power of the power supply and the number of the power supplies.

[0155] It should be noted that if the output power Pmax of all power supplies is less than or equal to the power demand P0 of N servers, the Nth server can be shut down and the power demand P0 of the remaining N-1 servers can be recalculated. If the output power Pmax of all power supplies is less than or equal to the power demand P0 of N-1 servers, the N-1th server can be shut down and the power demand P0 of the remaining N-2 servers can be recalculated. Similarly, if the output power Pmax of all power supplies is less than or equal to the power demand P0 of i servers, the i-th server can be shut down and the power demand P0 of the remaining i-1 servers can be recalculated; where i is less than or equal to N. The power protection strategy is exited until the power demand of the remaining servers is less than the output power of all power supplies. In this way, this embodiment can execute the shutdown of the server when the power demand P0 of the server is greater than or equal to the output power Pmax to reduce the power demand of the server and protect the power supply.
