Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 shows a schematic structural diagram of an elastic power supply system of a data center of the present disclosure.

The flexible power supply system 100 of the data center includes a mains power supply system and a flexible power supply system. The server 101 of the data center includes two power module groups for redundant power supply to the server, each power module group including a stable power module group 1011 for continuous power supply and an elastic power module group 1012 for elastic power supply.

The data center includes a plurality of servers, which may be the same type of servers or different types of servers, such as CPU (Central Process Unit, central processing unit) servers, GPU (Graphics Processing Unit, image processor) servers, ASIC (Application-Specific Integrated Circuit) servers, FPGA (Field-Programmable Gate Array, field programmable gate array) servers.

The two-way stable power supply circuit comprises a first stable power supply circuit and a second stable power supply circuit. Each server is correspondingly provided with two power module groups, namely a first power module group and a second power module group. The first power module group comprises a first stable power module and a first elastic power module group, and the second power module group comprises a second stable power module and a second elastic power module group. The first stable power supply module and the second stable power supply module are the two stable power supply modules. The stable power module group comprises at least one stable power module, and the elastic power module group comprises at least one elastic power module. The stabilized power supply module and the elastic power supply module may be of the same type, for example PSU modules, which are distinguished only by two different power supply situations, namely a stabilized power supply process and an elastic power supply process based on the stabilized power supply process.

Each of the two power module groups may provide sufficient power for the server. As an example, the stable power module group in each power module group includes two stable power modules, and the elastic power module group includes one elastic power module. The two stable power supply modules can supply power for the server under the conventional power supply condition, and when the power consumption requirement of the server is increased, the two stable power supply modules are further combined with one elastic power supply module to increase the power supply quantity of the server so as to elastically supply power to the server.

In order to further improve flexibility of elastic power supply and adaptability between the elastic power supply quantity and the servers, a server range for elastic power supply in the data center, and the number of stable power supply modules and elastic power supply modules in a power supply module group of the server in the server range can be determined according to service information and load characteristics of services processed by the data center.

The service information is information such as a service type, a service configuration, a service scale, and the like, and the load characteristic is characteristic information such as a load type, a load distribution, a load dynamic change, and the like.

As an example, when it is determined that the difference between the power consumption requirement of the data center in the normal state and the power consumption requirement of the data center in the peak state is large according to the service information and the load characteristic of the service processed by the data center, the elastic power module group including a large number of elastic power modules is set for the server on the basis that the power consumption requirement of the server of the data center in the normal state can be ensured based on the stable power module group, so that the power consumption requirement of the server is satisfied in the peak state.

When the difference between the power consumption requirement of the data center in a normal state and the power consumption requirement of the data center in a peak state is smaller according to the service information and the load characteristics of the service processed by the data center, the elastic power supply module group comprising a smaller number of elastic power supply modules is arranged for the server on the basis that the power consumption requirement of the server of the data center in the normal state can be ensured based on the stable power supply module group, and the power consumption requirement of the server can be met under the peak state.

The mains supply subsystem comprises two stable power supply circuits 102, wherein the two stable power supply circuits are connected with two stable power supply module groups in the two power supply module groups in a one-to-one correspondence manner and are used for providing mains supply for the server.

As an example, a first stabilized power supply circuit connected to a first stabilized power supply module group among the first power supply module groups of each server; and the second stable power supply circuit is connected with a second stable power supply module group in the second power supply module group of each server. Thus, in a conventional state, the commercial power is supplied to the servers in the data center in combination with two stable power supply circuits and two stable power supply module groups of each server.

The elastic power supply system comprises an energy storage device 103 and two elastic power supply circuits 104, wherein the two elastic power supply circuits are connected with two elastic power supply module groups in the two power supply module groups in a one-to-one correspondence manner and are used for providing electric energy in the energy storage device for the server under a first preset condition. The first elastic power module group and the second elastic power module group are the two elastic power module groups.

The first preset situation is that the power requirement of the server cannot be met by the stabilized power module set, for example, and more power needs to be provided to the server.

As an example, a first elastic power supply circuit is connected to a first elastic power supply module group of the first power supply module group of each server; and the second elastic power supply circuit is connected with a second elastic power supply module group in the second power supply module group of each server. Thus, in a first preset situation, the two stable power supply circuits and the two stable power supply module groups of each server are combined to provide the electric energy in the energy storage device for the servers in the data center.

In some optional implementations of this embodiment, the elastic power supply system is further configured to store the mains power via the energy storage device in a second preset condition.

The second preset condition is that, for example, the remaining power in the energy storage device is lower than a preset power threshold, and the power consumption requirement of the data center is lower than a preset power consumption threshold corresponding to the data center.

The preset electric quantity threshold and the preset electric quantity threshold can be specifically set according to actual conditions, and are not limited herein.

Taking the example that the electricity consumption requirement of the data center is lower than the preset electricity consumption threshold value, the current electricity consumption requirement of the data center is lower, the mains supply system does not need to provide mains supply for the data center, the electricity consumption requirement of the data center can be met, and partial electricity can be provided for the energy storage device.

In this implementation mode, under the second preset condition, the elasticity power supply electronic system stores the commercial power through the energy storage device to under data center has elasticity power supply demand, can satisfy data center's power consumption demand through the energy storage device, further improved elasticity power supply system's stability and flexibility.

In some alternative implementations of the present embodiment, the data center includes a plurality of server modules 105, each including a plurality of servers, and each server module is correspondingly provided with two stable power supply circuits.

In this implementation manner, the utility power supply subsystem is configured to, for each server module, provide, by using a redundancy manner, utility power for each server of the data center through one-to-one connection between two stable power supply circuits corresponding to the server module and two stable power supply module groups of each server under the server module.

Similarly, the two stable power supply circuits corresponding to each server module comprise a first stable power supply circuit and a second stable power supply circuit.

As an example, for each server module, the first stable power supply circuit corresponding to the server module is connected with the first stable power supply module group of each server under the server module; and the second stable power supply circuit corresponding to the server module is connected with the second stable power supply module group of each server under the server module. Therefore, in the conventional state, the two stable power supply circuits of the server module and the two stable power supply module groups of each server under the server module are combined, and the commercial power is provided for the servers in the data center in a redundancy mode.

In this implementation mode, with the server module as the unit, set up the two-way stable power supply circuit that a plurality of server modules correspond respectively, based on the two-way stable power supply circuit that the server module corresponds, adopt the redundant mode to supply power for the server under the server module, mutually independent, each other do not influence between a plurality of server modules, further improved the stability of elasticity power supply system.

In some optional implementations of this embodiment, each server module is correspondingly provided with two paths of elastic power supply circuits.

In this implementation manner, the elastic power supply system is configured to, for each server module, in a first preset situation, provide, through one-to-one correspondence connection between two elastic power supply circuits corresponding to the server module and two elastic power supply module groups of each server under the server module, electric energy in the energy storage device for each server of the data center in a redundancy manner.

Similarly, the two paths of elastic power supply circuits corresponding to each server module comprise a first elastic power supply circuit and a second elastic power supply circuit.

As an example, for each server module, the first elastic power supply circuit corresponding to the server module is connected with the first elastic power supply module group of each server under the server module; and the second elastic power supply circuit is connected with the second elastic power supply module group of each server under the server module group through the second elastic power supply circuit corresponding to the server module group. Therefore, under the first preset condition, the two paths of elastic power supply circuits of the server module and the two elastic power supply module groups of each server under the server module are combined, and the electric energy in the energy storage device is provided for the servers in the data center in a redundancy mode.

In the implementation mode, the server module is used as a unit, two paths of elastic power supply circuits corresponding to the plurality of server modules are arranged, the server under the server module is powered by adopting a redundancy mode based on the two paths of elastic power supply circuits corresponding to the server module, the plurality of server modules are mutually independent and do not affect each other, and the stability of the elastic power supply system under the elastic power supply condition is further improved.

In some alternative implementations of the present embodiment, the elastic power supply system is further configured to: determining whether a target server module in a second preset condition exists in the plurality of server modules; and the response to the determination comprises the step of storing the commercial power from the stable power supply circuit corresponding to the target server module through the energy storage device.

For the server module, the second preset condition is, for example, that the power consumption of the server module is lower than the preset power consumption threshold corresponding to the server module, that is, the server module is in a lower power consumption condition.

In this implementation manner, the elastic power supply system may monitor, in real time, the power consumption of each server module in the data center based on the PDU, the server management software, the cloud infrastructure management tool, and the like, so as to determine whether a target server module in the second preset situation exists in the plurality of server modules.

The multiple server modules in the data center may have different power requirements due to different load characteristics and different running services. For example, server module a is at a peak power usage and server module B is at a valley power usage.

For the target server module in the second preset condition, because the power consumption is low, part of the commercial power can be stored in the corresponding stable power supply circuit through the energy storage device, so that the power can be supplied to the target server module through the energy storage device under the condition that the power consumption of the target server module or other server modules except the target server is increased.

In this implementation mode, monitor the power consumption of every server module, when the second of server module in low power consumption presets the condition, the power supply circuit that stabilizes that the server module corresponds charges to energy storage device, on guaranteeing that energy storage device can satisfy data center's power consumption demand under the elasticity power supply condition, improved the utilization ratio of commercial power for elasticity power supply system more adapts to data center's peak valley running condition.

In some alternative implementations of the present embodiment, the elastic power supply circuit is connected to mains.

In this implementation, the elastic power supply system is further configured to: determining whether a target server module in a second preset condition exists in the plurality of server modules; and providing the commercial power in the stable power supply circuit corresponding to the target server module to the elastic power supply module group of the server in the server modules outside the target server module in response to the determination.

The plurality of server modules can be divided into a target server module in a second preset condition and other server modules except the target server module through monitoring the power consumption of each server module. For the target server module in the second preset condition, due to lower electricity consumption, part of the commercial power in the corresponding stable power supply circuit can be supplied to the elastic power supply module group of the server under the other server modules through the elastic power supply circuit corresponding to the other server modules so as to elastically supply power to the server under the other server modules.

In some alternative implementations, the execution entity may sort or filter other server modules than the target server module. For example, the server module in the first preset condition is selected from the other server modules, and part of the commercial power in the stable power supply circuit corresponding to the target server module is provided for the server module in the first preset condition in the other server modules. For another example, for the server module in the first preset situation in the other server modules, the priority of the server module may be determined according to the corresponding service and the deficiency information of the power consumption, and then, according to the priority, part of the commercial power in the stable power supply circuit corresponding to the target server module is provided to the server module in the first preset situation in the other servers.

In this implementation manner, the power consumption of each server module is monitored, and when the server module is in the second preset condition of low power consumption, part of the commercial power corresponding to the stable power supply circuit corresponding to the server module can be provided for other server modules to elastically supply power to other server modules. On the basis that the electricity consumption requirement of the data center can be met under the condition of ensuring elastic power supply, the utilization rate of the commercial power is improved, and the elastic power supply system is more suitable for the peak-to-valley running condition of the data center.

In some alternative implementations of the present embodiment, each server module includes two stable power distribution units and two flexible power distribution units. The two stable power supply distribution units comprise a first stable power supply distribution unit and a second stable power supply distribution unit, and the two elastic power supply distribution units comprise a first elastic power supply distribution unit and a second elastic power supply distribution unit.

The stable power supply distribution unit and the elastic power supply distribution unit are both PDU units, and are distinguished only by two different power supply situations of being applied to a stable power supply process and an elastic power supply process based on the stable power supply process.

In the commercial power supply system, for each server module, two stable power supply circuits corresponding to the server module are connected with two stable power supply distribution units of the server module and two stable power supply module groups of each server under the server module in a one-to-one correspondence mode.

As an example, for each server module, the first stable power supply circuit corresponding to the server module, the first stable power supply distribution unit of the server module, and the first stable power supply module group of each server under the server module are sequentially connected; the second stable power supply circuit corresponding to the server module is sequentially connected with the second stable power supply distribution unit of the server module and the second stable power supply module group of each server under the server module. Therefore, in the conventional state, the two stable power supply circuits of the server module, the two stable power supply distribution units and the two stable power supply module groups of each server under the server module are combined, and the redundancy mode is adopted to provide the commercial power for the servers in the data center.

In the elastic power supply system, for each server module, under a first preset condition, two paths of elastic power supply circuits corresponding to the server module are connected with two elastic power supply distribution units of the server module and two elastic power supply module groups of each server under the server module in a one-to-one correspondence mode.

As an example, for each server module, the first elastic power supply circuit corresponding to the server module, the first elastic power supply distribution unit of the server module, and the first elastic power supply module group of each server under the server module are sequentially connected; the second elastic power supply circuit corresponding to the server module is connected with the second elastic power supply module group of each server under the server module in sequence. Therefore, under the first preset condition, the two elastic power supply circuits of the server module, the two elastic power supply distribution units and the two elastic power supply module groups of each server under the server module are combined, and the electric energy in the energy storage device is provided for the servers in the data center in a redundancy mode.

In the implementation mode, each server module comprises two stable power supply distribution units and two elastic power supply distribution units, so that the reliability of the elastic power supply system is further improved.

Referring to fig. 2, fig. 2 is a flowchart of an elastic power supply method of a data center according to an embodiment of the disclosure. Wherein, in the process 200, the following steps are included:

step 201, combining two stable power supply circuits in a mains supply subsystem and two stable power supply module groups of a server of a data center, and providing mains supply for the server in a redundancy mode.

In this embodiment, an execution body (for example, a terminal device or a server) of the elastic power supply method of the data center may combine two stable power supply circuits in the mains power supply system and two stable power supply module groups of the server of the data center, and provide the mains power for the server in a redundancy manner. The server comprises two power module groups, wherein each power module group comprises a stable power module group for continuously supplying power and an elastic power module group for elastically supplying power.

The data center comprises a plurality of servers, and the servers can be servers of the same type or servers of different types, such as CPU servers, GPU servers, ASIC servers and FPGA servers.

The mains supply subsystem comprises two stable power supply circuits, wherein the two stable power supply circuits are connected with two stable power supply module groups in the two power supply module groups in a one-to-one correspondence manner and are used for providing mains supply for the server.

In some optional implementations of this embodiment, the data center includes a plurality of server modules, each server module includes a plurality of servers, and each server module is correspondingly provided with two stable power supply circuits. Similarly, the two stable power supply circuits corresponding to each server module comprise a first stable power supply circuit and a second stable power supply circuit.

In this implementation manner, the execution body may execute the step 201 as follows: and for each server module, combining two stable power supply circuits corresponding to the server module and two stable power supply module groups of each server under the server module, and providing commercial power for each server of the data center in a redundancy mode.

Step 202, determining the current operation situation of the data center.

In this embodiment, the executing body may determine a current operation situation of the data center.

As an example, the execution body may acquire the operation parameters of the data center, further analyze the operation parameters, and determine the current operation situation of the data center. The running situations can be classified according to actual situations. The operating conditions include, for example, a first preset condition and a second preset condition. The first preset situation is that the power requirement of the server cannot be met by the stabilized power module group, and more power needs to be provided to the server. The second preset condition is that, for example, the remaining power in the energy storage device is lower than a preset power threshold, and the power consumption requirement of the data center is lower than a preset power consumption threshold corresponding to the data center.

In step 203, in response to determining that the data center is in the first preset condition, the two elastic power supply circuits in the elastic power supply system and the two elastic power supply module groups of the server are combined, and the electric energy in the energy storage device in the elastic power supply electronic system is provided for the server in a redundancy manner.

In this embodiment, the executing body may combine two paths of elastic power supply circuits in the elastic power supply system and two paths of elastic power supply module groups of the server to provide the electric energy in the energy storage device in the elastic power supply subsystem for the server in a redundancy manner in response to determining that the data center is in the first preset condition.

As an example, a first elastic power supply circuit is connected to a first elastic power supply module group of each server; and the second elastic power supply circuit is connected with the second elastic power supply module group of each server. Thus, in a first preset situation, the two stable power supply circuits and the two stable power supply module groups of each server are combined to provide the electric energy in the energy storage device for the servers in the data center.

In some optional implementations of this embodiment, the executing body may execute the step 203 as follows: for each server module, in response to determining that the server module is under a first preset condition, combining two elastic power supply circuits corresponding to the server module and two elastic power supply module groups of each server under the server module, and providing electric energy in an energy storage device for each server in a redundancy mode. Similarly, the two paths of elastic power supply circuits corresponding to each server module comprise a first elastic power supply circuit and a second elastic power supply circuit.

In some optional implementations of this embodiment, the foregoing execution body may further perform the following operations: and in response to determining that the data center is in the second preset condition, storing the commercial power through the energy storage device.

Taking the example that the second preset condition is that the electricity consumption requirement of the data center is lower than the preset electricity consumption threshold, the fact that the current electricity consumption requirement of the data center is lower is indicated, the mains supply system does not need to provide mains supply for the data center, the electricity consumption requirement of the data center can be met, and partial electricity can be provided for the energy storage device.

In some optional implementations of this embodiment, the executing entity may store the commercial power based on the energy storage device by:
