Description

Technical Field

[0001] This application relates to the field of power electronics technology, and more particularly to a server and a method. Background Technology

[0002] Due to the stringent requirements of data centers for power supply stability, and to avoid instability caused by circuit anomalies, dual power supplies are typically used to power servers simultaneously. This reduces the risk of server equipment being forced to shut down due to power failure. A power outage refers to a break in the power supply circuit or insufficient voltage due to voltage fluctuations over a period of time.

[0003] This approach requires the total actual load of the two loads to be less than half of their rated load over a long period, resulting in a significant waste of the data center's power resources. Improving the utilization efficiency of the data center's power resources while ensuring that the operation of electrical appliances is not affected by power outages has become a major challenge. Summary of the Invention

[0005] A first aspect of the present invention provides a server, comprising: a first PDU, a second PDU, a battery, a power manager, and a power-consuming unit; the first PDU is electrically connected to the power-consuming unit and is used to supply power to the power-consuming unit; the second PDU is electrically connected to the power-consuming unit and is used to supply power to the power-consuming unit; the battery is electrically connected to the first PDU and the second PDU and is used to provide power to the power-consuming unit through the first PDU when the first power supply fails, and / or to provide power to the power-consuming unit through the second PDU when the second power supply fails; the power manager is electrically connected to the first power supply, the second power supply, and the battery and is used to acquire the power supply status of the first power supply and the second power supply; when the first power supply fails, a first power supply signal is sent to the battery, the first power supply signal indicating that power is being supplied to the power-consuming unit; when the second power supply fails, a second power supply signal is sent to the battery, the second power supply signal indicating that power is being supplied to the power-consuming unit.

[0006] The server supplies power for the power-consuming unit through the first PDU and the second PDU, wherein the battery is electrically connected with the first PDU, the second PDU and the power manager, when the first power supply is powered off, the battery unit supplies power for the power-consuming unit through the first PDU; when the second power supply is powered off, the battery unit supplies power for the power-consuming unit through the second PDU. The power manager is electrically connected with the first power supply, the second power supply and the battery, after obtaining the power supply conditions of the first power supply and the second power supply, if the first power supply is powered off, a first power supply signal is sent to the battery, the first power supply signal indicates to supply power for the power-consuming unit; if the second power supply is powered off, a second power supply signal is sent to the battery, the second power supply signal indicates to supply power for the power-consuming unit. Through the cooperation of the battery and the power manager, the goal of supplying power for the power-consuming unit by the battery when the power supply is temporarily powered off is achieved, in use, there is no need to long-term use one power supply as a backup, the resource waste caused by using one power supply as a backup is eliminated, and the utilization efficiency of the power resource of the machine room is improved.

[0007] In a possible implementation manner of the first aspect, the server further comprises a backup power supply, when the first power supply is powered off and the second power supply is powered off, the power manager is further configured to send a third power supply signal to the backup power supply and a second power supply signal to the battery, or send a fourth power supply signal to the backup power supply and a first power supply signal to the battery; the third power supply signal indicates that the backup battery supplies power for the power-consuming unit through the first PDU, and the fourth power supply signal indicates that the backup battery supplies power for the power-consuming unit through the second PDU.

Since the current server and the design of the machine room usually have a backup power supply, if the backup power supply is used to supply power for one of the two power supplies when the two power supplies are powered off at the same time, the power supply pressure of the battery unit can be reduced, the capacity of the battery can be reduced, and the floor space occupied by the battery can be reduced.

[0029] The embodiments of the present application are described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Those skilled in the art can know that with the development of technology and the emergence of new scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0030] The terms "first", "second", and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] In order to ensure the stability of the server, the data center adopts two power supplies to supply power to the server to avoid the impact of power failure on the devices in the server. Please refer to Figure 1 , Figure 1 A diagram of a server power supply architecture provided by an embodiment of the present application is shown in FIG. 1. As shown in FIG. 1, the server power supply architecture includes a power supply A and a power supply B. Figure 1 It can be seen that the power supply A supplies power to the server 1 through a PDU-A1 interface of a power distribution unit (PDU) in the server, and the power supply B supplies power to the server 2 through a PDU-B1 interface of the power supply PDU in the server, so that the server 1 can take power from the power supply A and the power supply B at the same time, and when the power supply A or the power supply B fails, the server 1 can still work normally. The rated power of the power supply A and the power supply B is P, and the rated power of the server 1 is P. Although this power supply architecture improves the stability of the server, it causes a waste of resources due to the long-term idling of the entire standby power supply.

[0032] In combination with the actual situation, the probability of power failure is very low, and the power failure time is usually within 30 minutes. The embodiment of the application provides a server for improving the total power of the server and the computing power of the data center on the basis of the existing machine room circuit. The application also provides a power supply method, a computer readable storage medium and a computer program product. The following will be described in detail.

[0033] The server provided by the embodiment of the application is applied to the server of the data center. The server can accommodate standard or non-standard power-consuming units such as switches, computing devices and network storage, and provide power for these power-consuming units.

[0034] The server provided by the embodiment of the application can be combined with Figure 2 understand, Figure 2 A structural schematic diagram of the server provided by the embodiment of the application is shown in the figure. The server 21 includes a first rectifier 211, a second rectifier 212, a first PDU 214, a second PDU 215, a battery 213, a power manager 216 and a power-consuming unit 24.

[0035] The first rectifier 211 is electrically connected with the first power supply 22 and the first PDU 214, and is used to convert the alternating current provided by the first power supply 22 into direct current, and provide the power-consuming unit 24 with the maximum first power through the first PDU 214.

[0036] The second rectifier 212 is electrically connected with the second power supply 23 and the second PDU 215, and is used to convert the alternating current provided by the second power supply 23 into direct current, and provide the power-consuming unit 24 with the maximum second power through the second PDU 215.

[0037] The first PDU 214 is electrically connected with the power-consuming unit 24 and the battery 213, and is used to provide the power-consuming unit 24 with the maximum first power.

[0038] The second PDU 215 is electrically connected with the power-consuming unit 24 and the battery 213, and is used to provide the power-consuming unit 24 with the maximum second power.

[0039] The battery 213 is electrically connected with the power-consuming unit 24, and is used to provide the power-consuming unit 24 with the maximum first power when the first power supply 22 is powered off, or provide the power-consuming unit 24 with the maximum second power when the second power supply 23 is powered off.

[0040] The power manager 216 is electrically connected with the first power supply 22, the second power supply 23 and the battery 213, and is used to obtain the working conditions of the first power supply 22 and the second power supply 23, and schedule the battery 213 according to the working conditions of the first power supply 22 and the second power supply 23.

[0041] Based on the foregoing structure, the working conditions of the first power supply 22 and the second power supply 23 are different, and the specific implementation is divided into three cases, which will be introduced as follows:

[0042] Case one: the first power supply 22 is powered off and the second power supply 23 is normally working.

[0043] After detecting the working conditions of the first power supply 22 and the second power supply 23, if the first power supply 22 is powered off and the second power supply 23 is normally working, the power manager 216 sends a first power supply signal to the battery 213, and the first power supply signal indicates that the maximum first power of the electric energy is provided for the power-consuming unit 24 through the first PDU 214.

[0044] For example, the specific power supply condition can be referred to Figure 3 , Figure 3 A working state diagram of a server provided by the embodiment of the application.

[0045] In the diagram, the first power supply 22 is powered off, the second power supply 23 is normally working, and the battery 213 replaces the first power supply 22, is electrically connected with the first PDU 214, and provides the electric energy for the power-consuming unit through the first PDU 214. The second power supply 23 is electrically connected with the second rectifier 212, the second rectifier 212 converts the alternating current provided by the second power supply 23 into direct current, and provides the electric energy for the power-consuming unit 24 through the second PDU 215.

[0046] For example, if the first power supply 22 and the second power supply 23 provide 5kw of electric energy for the power-consuming unit in the working state, when the first power supply 22 is powered off and the second power supply 23 is normally working, the battery 213 replaces the first power supply 22, is electrically connected with the first PDU 214, and provides 5kw of electric energy for the power-consuming unit through the first PDU 214. The second power supply 23 is electrically connected with the second rectifier 212, the second rectifier 212 converts the alternating current provided by the second power supply 23 into direct current, and provides 5kw of electric energy for the power-consuming unit 24 through the second PDU 215. Then, the server can support a power-consuming unit of 10kw at most.

[0047] It should be noted that the introduction of the first power supply, the second power supply, and the battery providing 5kw of electric energy for the power-consuming unit is only an example, and in actual application, it should be adjusted according to the actual situation, which is not limited herein.

[0048] Case two: the first power supply 22 is normally working and the second power supply 23 is powered off.

[0049] If the first power supply 22 is normally working and the second power supply 23 is powered off, the power manager 216 sends a second power supply signal to the battery 213, and the second power supply signal indicates that the maximum second power of the electric energy is provided for the power-consuming unit 24 through the second PDU 215.

[0050] For example, please refer to the following table for the power supply conditions Figure 4 , Figure 4 Another working state diagram of the server provided in the embodiment of the present application.

[0051] The first power supply 22 is in normal operation, the second power supply 23 is powered off, and the battery 213 replaces the second power supply 23 and is electrically connected with the second PDU 215 to provide power for the power-consuming unit 24 through the second PDU 215. The first power supply 22 is electrically connected with the first rectifier 211, and the first rectifier 211 converts the alternating current provided by the first power supply 22 into direct current to provide power for the power-consuming unit 24 through the first PDU 215.

[0052] For example, if the first power supply 22 and the second power supply 23 provide 5kw of power for the power-consuming unit in the working state, when the first power supply 22 is in normal operation and the second power supply 23 is powered off, the battery 213 replaces the second power supply 23 and is electrically connected with the second PDU 215 to provide 5kw of power for the power-consuming unit through the second PDU 215. The first power supply 22 is electrically connected with the first rectifier 211, and the first rectifier 211 converts the alternating current provided by the first power supply 22 into direct current to provide 5kw of power for the power-consuming unit 24 through the first PDU 214. Then the server can support a power-consuming unit of up to 10kw.

[0053] It should be noted that the above description that the first power supply, the second power supply and the battery provide 5kw of power for the power-consuming unit is only an example, and in actual application, it should be adjusted according to the actual situation, which is not limited herein.

[0054] Case three: the first power supply 22 and the second power supply 23 are powered off at the same time.

[0055] If the first power supply 22 and the second power supply 23 are powered off at the same time, the power manager 216 sends the first power supply signal and the second power supply signal to the battery 213. After receiving the first power supply signal and the second power supply signal sent by the power manager 216, the battery 213 provides power of a maximum third power for the power-consuming unit 24, and the third power is the sum of the first power and the second power.

[0056] For example, please refer to the following table for the power supply conditions Figure 5 , Figure 5 Another working state diagram of the server provided in the embodiment of the present application.

[0057] When the first power supply 22 and the second power supply 23 are simultaneously powered off, the battery 213 replaces the first power supply 22, is electrically connected with the first PDU 214, and provides electric energy of the third power for the electric unit 24 through the first PDU 214, and / or the battery 213 replaces the second power supply 23, is electrically connected with the second PDU 215, and provides electric energy of the third power for the electric unit 24 through the second PDU 214. Specifically, the battery 213 provides electric energy of the third power for the electric unit 24.

[0058] For example, if the first power supply 22 and the second power supply 23 provide electric energy of 5kw for the electric unit in the working state, when the first power supply 22 and the second power supply 23 are simultaneously powered off, the battery 213 replaces the first power supply 22, is electrically connected with the first PDU 214, and provides electric energy of 5kw for the electric unit through the first PDU 214, and the battery 213 replaces the second power supply 23, is electrically connected with the second PDU 215, and provides electric energy of 5kw for the electric unit through the second PDU 215. That is, the battery 213 provides electric energy of 10kw for the electric unit through the first PDU 214 and the second PDU 315.

[0059] Or, if the first power supply 22 and the second power supply 23 provide electric energy of 5kw for the electric unit in the working state, when the first power supply 22 and the second power supply 23 are simultaneously powered off, the battery 213 replaces the first power supply 22, is electrically connected with the first PDU 214, and provides electric energy of 10kw for the electric unit through the first PDU 214, or the battery 213 replaces the second power supply 23, is electrically connected with the second PDU 215, and provides electric energy of 10kw for the electric unit through the second PDU 215. That is, the battery 213 provides electric energy of 10kw for the electric unit through the first PDU 214 or the second PDU 315.

[0060] It should be noted that the above description that the first power supply, the second power supply and the battery provide electric energy of 5kw for the electric unit is only an example, and should be adjusted according to actual conditions in actual application, which is not limited herein.

[0061] It should be noted that whether the examples mentioned in the embodiments of the present application can be implemented depends on the current capacity of the battery 213, and it is considered herein that the current capacity of the battery 213 can provide electric energy of 30min for the electric unit at 240v direct current voltage. According to the above examples, that is, when the capacity of the battery is greater than or equal to 10kv, the examples can be implemented. In actual application, the current capacity of the battery and whether the battery can provide sufficient electric energy for the electric unit are not limited, and should be adjusted according to specific application scenarios.

[0062] In the embodiment, the first rectifier 211 is added to the server 21, the second rectifier 212 and the battery 213 are added to the server 21, the first rectifier 211 is used to convert the alternating current provided by the first power supply 22 into direct current to provide the maximum first power for the power unit, the second rectifier 212 is used to convert the alternating current provided by the second power supply 23 into direct current to provide the maximum second power for the power unit, when the first power supply 22 is powered off, the battery 213 provides the maximum first power for the power unit, when the second power supply 23 is powered off, the battery 213 provides the maximum second power for the power unit. The battery 213 can provide the maximum third power for the power unit 24, and the third power is the sum of the first power and the second power. While ensuring the stability of the power supply of the power unit 24 in the server 21, the utilization rate of the power resource of the computer room is improved.

[0063] Since in actual application, the server 21 of the data center can also be connected with the standby power supply, please refer to Figure 6 , Figure 6 Another structure schematic diagram of the server provided in the embodiment is provided. The server 21 comprises: a first rectifier 211, a second rectifier 212, a first PDU 214, a second PDU 215, a battery 213 and a power manager 216.

[0070] Based on the foregoing structure, the working conditions of the first power supply 22 and the second power supply 23 are different, and the specific implementation is divided into three cases, which will be introduced as follows.

[0071] Case one: the first power supply 22 is powered off and the second power supply 23 is normally working.

[0078] When the first power supply 22 and the second power supply 23 are powered off at the same time, the standby power supply 25 is started. The battery 213 replaces the second power supply 23 and is electrically connected to the second PDU 215 and provides electric energy for the electric unit 24 through the second PDU 215.
