Detailed Description
Fig. 1 is a schematic diagram of a power supply system. As shown in fig. 1, the power supply system may include: automatic Transfer Switch (ATS), main transformer (transformers N1-N4), redundant transformer (transformer-R), Uninterruptible Power System (UPS), Static Transfer Switch (STS), power supply, server, etc. The ATS is used for switching a main power supply and a standby power supply, the input of the ATS is generally two inputs, one of the two inputs is the input of a 10KV power distribution A circuit serving as a high-voltage main power supply, the other input of a 10KV power distribution B circuit serving as a high-voltage standby power supply, and when the high-voltage main power supply fails, the ATS is switched to the high-voltage standby power supply to supply power to a rear-end load. The UPS is used for providing uninterrupted current, when the UPS front-end equipment or cable is in normal power supply, the UPS supplies the current output by the transformer to the back-end load after stabilizing the voltage and stores part of the current properly, when the UPS front-end equipment or cable is in failure, the UPS can continue to supply power to the load by using the stored part of the current within a certain time period, and the load can be ensured to temporarily maintain normal operation.
The power distribution A circuit obtains current from the commercial power A circuit, the power distribution B circuit obtains current from the commercial power B circuit, and the commercial power A circuit and the commercial power B circuit are power supply circuits provided by a power supply office.
Further, under the condition that the utility line A and the utility line B both have faults (for example, power failure of a power supply office), current can be provided to the distribution line A and the distribution line B in a diesel power generation mode for temporary power supply.
For STS1, STS1 includes a first interface connected to UPS-N1, a second interface connected to UPS-R, and a third interface connected to power supply 1, and STS1 preferentially provides the current of UPS-N1 obtained by the first interface to the third interface when the first interface obtains the current provided by UPS-N1. The STS1 provides the current of the UPS-R sourced by the second interface to the third interface when the current provided by the UPS-N1 is unavailable at the first interface.
For the STS2, the STS2 includes a fourth interface, a fifth interface, and a sixth interface, the fourth interface is connected to the UPS-N1, the fifth interface is connected to the UPS-R, the sixth interface is connected to the power supply 2, and the STS2 preferentially provides the current of the UPS-N1 obtained by the fourth interface to the sixth interface when the fourth interface obtains the current provided by the UPS-N2. The STS2 provides the current of the UPS-R obtained by the fifth interface to the sixth interface when the current provided by the UPS-N1 is not available at the fourth interface.
Specifically, the power is the multiplication of the current and the voltage, the current provided by the UPS corresponds to the voltage of the power supply provided to the server (which may be converted by the transformer), the UPS provides the same current to the STS, if the power required by the server is P, the UPS-N1 provides P/2 power to the first interface of the STS1, P/2 power to the fourth interface of the STS2, the UPS-R provides P/2 power to the second interface of the STS1, and P/2 power to the fifth interface of the STS 2.
It is to be understood that 1, 2, 3, 4, 5, 6, etc. in fig. 1 identify the identity of an interface, e.g. 1 denotes a first interface, 2 denotes a second interface, etc.
Therefore, under normal conditions, the server is powered by the link where the main transformer is located, and the link where the redundancy transformer R is located serves as a hot backup and does not bear load. When the main power supply link fails (specifically, for example, when the UPS-N output on the main power supply link fails), the STS switch switches the interface to switch the main power supply link to the standby power supply link, that is, the STS switch switches the load to the link where the redundant transformer R is located to continue supplying power to the server.
And, the server includes power 1 and power 2 inside, these two power are load balancing mode when supplying power, that is to say, normally, supply power for the server by power 1 and power 2 on the main power supply link simultaneously, these two power each undertake 50% load. After the STS switch switches the main power supply link to the standby power supply link, the server is also powered by both power supply 1 and power supply 2. It should be noted that fig. 1 is only a schematic illustration, and in practical applications, the number of the main transformers may also be 5, 6, etc., the number of the servers may also be more, and the number of the power supplies may also be more.
It should be noted that, in fig. 1, the commercial power a and the commercial power B are normally supplied at the same time, and when the commercial power a and the commercial power B fail, a standby power supply, such as a diesel engine, may be used to supply power. The connection relationship between the transformer N1, the transformer N2, the transformer N3, the transformer N4, and the transformer R and the commercial power is not limited. As an example, the transformer N1, the transformer N3, and the transformer R may be connected to the commercial power a line, and the transformer N2, the transformer N4 may be connected to the commercial power B line. When one of the commercial power circuit a and the commercial power circuit B has a fault, for example, when the commercial power circuit B has a fault, the transformer N2 and the transformer N4 can be switched to the commercial power circuit a through an Automatic Transfer Switch (ATS). Of course, it is to be understood that the connection relationship is not limited to the above examples.
In the power supply system, if equipment or cables between the STS1 and the transformer-N1 are in failure, the STS1 needs to be switched to UPS-R power supply, and according to the power supply system, a large number of STS cabinets need to be configured, so that the construction cost of a data center is high. Moreover, the STS occupies the space of the cabinet, and the defects are obvious for the area with deficient land resources. In addition, the STS switching involves the switch actuation and disconnection under the loaded state, and high temperature is likely to occur at the electric shock position, which leads to resistance increase and poor reliability.
In view of this, embodiments of the present application provide a new power supply system, in which a power supply control device in a server controls switching of power modules, so as to implement power supply switching, and an STS switch is not required, so that construction cost of a data center can be reduced, and reliability can be improved.
Further, based on a new power supply system, the embodiment of the application provides a new solution, and a complete solution for planning, delivering, operating and maintaining the full life cycle stages of the server is formed through a delivering device and an operating and maintaining device.
At least one of the embodiments of the present application includes one or more, where a plurality means greater than or equal to two. In the description of the present application, the terms "first", "second", and the like are used for the purpose of distinguishing between objects to be described, and are not intended to indicate or imply relative importance nor order to be construed.
Fig. 2 is a schematic diagram of a power supply system of a data center according to an embodiment of the present disclosure. Fig. 2 is compared to fig. 1 with a reduced STS switch and a different load pattern of the power supply supplying the server. Specifically, in fig. 2, when the server is powered by the power supply 1 and the power supply 2, the power supply 1 serves as a main power supply to supply power to the server, and the power supply 2 serves as a backup power supply without a load. When the UPS-N breaks down, the standby power supply 2 is started immediately, and the server load is supplied with power by the standby power supply 2 independently, so that continuous power supply of the server is ensured.
For convenience of description, in the embodiments of the present application, the power supply modules may be respectively referred to as a "first power supply module" and a "second power supply module".
It should be noted that, in the power supply system, at least one main power supply link, at least one backup power supply link, and a plurality of servers may be included. Each server may include a power supply control device (for example, implemented by a Baseboard Management Controller (BMC)), a first power module (e.g., power supply 1), and a second power module (e.g., power supply 2). The power supply 1 is electrically connected with a main power supply link, the power supply 2 is electrically connected with a standby power supply link, the main power supply link is used for supplying power to the power supply 1, and the standby power supply link is used for supplying power to the power supply 2. The power supply control device, the power supply 1, and the power supply 2 are provided on the main board of the server.
As an example, in FIG. 2, the primary power supply link may include transformer-N1, UPS-N1, cables between transformer-N1 and UPS-N1, and cables between UPS-N1 and power supply 1. The backup power link may include transformer-R, UPS-R, a cable between transformer-R and UPS-R, and a cable between UPS-R and power source 2.
Of course, it will be appreciated that the main power link may also include transformer-N2, UPS-N2, cables between transformer-N2 and UPS-N2, and cables between UPS-N2 and power supply 1; transformer-N3, UPS-N3, cables between transformer-N3 and UPS-N3, and cables between UPS-N3 and power supply 1.
Fig. 3 is a flowchart of a power supply method according to an embodiment of the present application, and referring to fig. 3, the method may include the following steps:
step 301: the power supply control device acquires a first voltage and a second voltage.
For convenience of description, the input voltage of the first power supply module may be referred to as a "first voltage" and the input voltage of the second power supply module may be referred to as a "second voltage" hereinafter. The first voltage is obtained by the first power supply module from the main power supply link, and the second voltage is obtained by the second power supply module from the standby power supply link.
In one possible implementation, the first power module may include a first power source therein, and the second power module may include a second power source therein. That is, the first power module and the second power module respectively include a power source, for example, referring to fig. 4A, it is assumed that the power source 1 is the first power source and the power source 2 is the second power source.
In yet another possible implementation, the first power module may include at least two first power sources, and the second power module may include at least two second power sources. That is, the first power module and the second power module may include at least two power supplies, respectively. Illustratively, as shown in fig. 4B, a first power module included in the server may include a power supply 1 and a power supply 2, and a second power module may include a power supply 3 and a power supply 4.
Of course, it is understood that fig. 4B is only a schematic illustration, and the first power module and the second power module may also include three or more power supplies, or the first power module includes two power supplies, the second power module includes three power supplies, or the first power module includes three power supplies, the second power module includes two power supplies, and the like, which is not limited in this application.
Step 302: the power supply control device determines the first power supply module as a main power supply module and determines the second power supply module as a standby power supply module according to the voltage difference between the first voltage and the second voltage.
In this embodiment of the application, after the power supply control device obtains the first voltage and the second voltage, the first voltage obtained by the first power module from the main power supply link and the second voltage obtained by the second power module from the standby power supply link may be compared, and then the operating mode of the power module is set according to the obtained voltage of the power module. Specifically, assuming that the first voltage is higher than the second voltage, the first power module may be set as a main power module, and the second power module may be set as a standby power module; if the first voltage is lower than the second voltage, the first power supply module can be set as a standby power supply module, and the second power supply module can be set as a main power supply module. That is, the power supply control device determines the power module with high voltage as the main power module and determines the power module with low voltage as the standby power module.
For example, taking the case that the first voltage is higher than the second voltage, the power supply control device may determine a first power module that acquires the first voltage from the main power link as the main power module, and determine a second power module that acquires the second voltage from the backup power link as the backup power module.
In an alternative embodiment, the power module with the lower acquired voltage may also be set as a main power module, and the power module with the higher acquired voltage may also be set as a backup power module.
It should be noted that, before setting the working mode of the power supply module, the power supply control device may determine that its version supports setting the active/standby working mode, and may further set the working mode of the power supply module. For example, in the present application, a version of the power supply control device that supports setting of the active/standby operating mode may be preconfigured, for example, a version above V5.0 is configured to support setting of the active/standby operating mode, so before the operating mode of the power module is set, a version number of the power supply control device may be obtained first, and whether the version number of the power supply control device meets a configuration condition may be determined. If the condition is satisfied, the operating mode of the power module may be set.
Next, taking the first power module as a main power module and the second power module as a standby power module as an example, the description of fig. 4A and 4B is continued.
As an example, for example, as shown in fig. 4A, when the power supply 1 is a main power supply module and the power supply 2 is a standby power supply module, normally, the power supply controller selects the power supply 1 to supply power alone to the motherboard of the server, the power supply 2 is idle as the standby power supply module of the server, and the power supply 1 supplies 100% of the current (or electric power) required by the server when supplying power to the motherboard of the server, and the power supply 2 has no load.
In the case where the main power supply module includes at least two first power supplies, the at least two first power supplies may supply electric power to the server in a parallel manner; in the case where the standby power module includes at least two second power sources, the at least two second power sources may supply electric power to the server in a parallel manner.
As another example, for example, as shown in fig. 4B, when the power supply 1 and the power supply 2 are arranged in parallel as a main power supply module and the power supply 3 and the power supply 4 are arranged in parallel as a standby power supply module, the server is normally simultaneously supplied with power by the power supply 1 and the power supply 2 in parallel, and the power supply 3 and the power supply 4 have no load. That is, when the main power supply module includes at least two power supplies, the power supplies 1 and 2 are in a load balancing mode, and the power supplies 1 and 2 each supply 50% of current (or electric power) to the server.
It should be noted that fig. 4A and 4B are only for schematically illustrating a load situation when the power supply supplies power to the server, and in practical applications, the power supply may be installed inside the server as one device of the server.
Further, before the power supply control device sets the operating mode of the power supply module, that is, before the power supply control device determines that the first power supply module is the main power supply module and the second power supply module is the standby power supply module, it may be determined that the power supply versions in the first power supply module and the second power supply module support setting of the active/standby operating mode.
As a possible implementation manner, in the present application, a power version supporting setting of the active/standby operating mode may be configured in advance, for example, a version above V7.0 is configured to support setting of the active/standby operating mode, so before the operating mode of the power module is set, a version number of the power may be obtained first, and whether the power version number meets a configuration condition is determined. If both the main power supply and the standby power supply meet the conditions, the main/standby operating mode may be set. If one of the main power supply and the standby power supply does not meet the condition, firmware upgrading can be carried out on the power supply which does not meet the condition, so that the upgraded power supply version is the version supporting setting of the main/standby working mode.
Step 303: the power supply control device selects the main power supply module to independently supply power to the server, and selects the standby power supply module to independently supply power to the server under the condition that the main power supply link fails.
In the embodiment of the application, after the power supply control device determines that the first power supply module is the main power supply module, the main power supply module can be selected to supply power to the server independently, and the standby power supply module has no load. If the main power supply link fails, the main power supply link is switched to the standby power supply link, and the standby power supply module independently supplies power to the server continuously.
It should be noted that, the failure of the main power supply link may be a cable failure, or may be a failure of a device on the main power supply link, which is not limited in this application.
For example, in fig. 4A, if a device (e.g., transformer-N1) on the primary power supply link fails or a cable fails, the power supply control device may switch the primary power supply link to the backup power supply link, and the power supply 2 may supply power to the server to ensure normal power supply to the server. After the main power supply link returns to normal, the main power module on the main power supply link can continue to supply power for the server.
As yet another example, taking FIG. 4B as an example, the servers are normally powered by power supplies 1 and 2, and if the primary power link fails, the primary power link may be switched to the backup power link, and the servers are powered by power supplies 3 and 4.
In the application, the power supply link switching is realized by the power supply control device inside the server, and compared with a scheme of switching through the STS, the reliability can be improved, and the construction cost of the data center can be reduced.
Further, in the embodiment of the application, under the condition that the electric power required by the server is judged to exceed the rated power of the main power supply module, the standby power supply module is selected to supply supplementary power for the server, wherein the power exceeding the rated power is borne by the standby power supply module. That is, if the power of the server exceeds the rated power of the power supply module, the excess may be taken over by the backup power supply module.
For example, assuming that the power of the server is 1000w and the rated power of the power module is 800w, the excess 200w can be borne by the standby power module. That is to say, in the embodiment of the present application, no matter when the main power supply link fails or the server power is overloaded, the control mode of the power module maintains the main/standby operating mode, and is not switched to the load balancing mode.
Further, in the same server, the power supply control device can send different control signals to the power supply, wherein the control signal 1 can control the power supply to output current to the mainboard of the server so as to supply power to the server, the control signal 2 can control the power supply to be idle, the power supply can not output current to the mainboard of the server, and the power supply control device can select different power supplies to supply power to the server by sending the control signals.
And, the power supply can send status information to the power supply control device, the status information is used for indicating whether the power supply receives the current sent by the power supply link.
In addition, when the power module is in the main/standby operating mode, if the power of the server exceeds 75% of the rated power of the power module, the operating mode of the power module still maintains the main/standby operating mode, and the power module does not enter the load balancing mode. In other words, in the present application, when the server power exceeds a preset multiple of the rated power of the power module, the operating mode of the power module maintains the active/standby operating mode.
The following description will proceed with the power supply method referred to in the present application, taking a power supply system as an example. In the power supply system of the present application, at least one primary power supply link, at least one backup power supply link, and a plurality of servers may be included. The server comprises a server body, a plurality of servers and a power supply control device, wherein the server body is provided with the server body, the server body is provided with the server body, the server is provided with the server body, the server is provided with the server body power supply unit, the server is provided with the server, the server body power supply unit, the server is provided with the server, the server is provided with the server, the server body power supply unit, the server is provided with the server, the server.
Referring to fig. 5, a schematic diagram of a power supply system according to an embodiment of the present disclosure is provided, the schematic diagram is divided by modules, and the system may include: the power supply control device 501, the first power module 5021, the second power module 5022, the delivery device 503 and the operation and maintenance device 504.
It is understood that the system shown in fig. 5 is partitioned in modules, and does not conflict with the above-described system partitioned by structure, and the two are different only in the angle of partitioning the system.
It should be noted that, for the functions corresponding to the power supply control device, reference may be specifically made to the description in the embodiment shown in fig. 3, and details are not repeated here.
Further, a delivery device in the system may be configured to notify the power supply control device to configure the first power module and the second power module in the active/standby operating mode.
And the operation and maintenance device can be used for inquiring whether the first power supply module and the second power supply module are configured to be in the main and standby working modes or not to the power supply control device.
Furthermore, when the working modes of the first power module and the second power module are not the main standby working mode, the operation and maintenance device is further configured to notify the power supply control device to configure the first power module and the second power module into the main standby working mode.
The power supply method of the embodiment of the present application is described below with reference to practical engineering implementation. Referring to fig. 6, an implementation flowchart according to an embodiment of the present application is shown. As shown in fig. 6, the process may include a planning phase, a delivery phase, an operation and maintenance phase, and the like. These processes are described separately below.
The first stage is as follows: planning phase
At this stage, the engineer may enter the machine room power supply information of the data center on the planning platform, for example, the power supply modes of the servers of the machine room include a power supply mode without an STS switch and a power supply mode with an STS switch.
And a second stage: delivery phase
In the embodiment of the present application, the delivery device may have a function of setting the active/standby operating modes in batches, and may limit the maximum batch upgrading number in order to prevent the standby power supply link from being overloaded.
Specifically, the method can comprise the following steps:
1) the delivery device can read the power supply information of the machine room from the planning platform.
2) And issuing a setting function for starting the main/standby working modes.
And if the delivery device reads that the power supply mode of the cabinet in the machine room is the power supply mode without the STS switch, issuing a command for starting the main/standby working mode setting function to the power supply control device.
3) And judging that the main/standby working mode is set.
In practical applications, an administrator of the data center needs to select which servers use the scheme without the STS switch and which servers use the scheme with the STS switch. It will be appreciated that servers using the STS switch and servers not using the STS switch may be tagged with different identifications for the administrator to look up.
And after the administrator selects the server without the STS switch, changing the wiring mode of the server, removing the STS cabinet, and informing the power supply control device to set the power supply module to be in the main/standby working mode by using the delivery device. In this process, the power supply control device needs to determine that its version supports the active/standby operating mode, and needs to determine that the version of the power supply module supports the active/standby operating mode. If the version of the power supply control device and/or the version of the power module do not support the active/standby working mode, the power supply control device and/or the power module can support the active/standby working mode by updating the firmware version number of the power supply control device and/or the firmware version number of the power module. Thus, a server that does not use the STS switch can be recorded with the updated firmware version number.
4) And entering a main/standby configuration state.
5) And detecting whether the version of the power supply control device supports setting of the main/standby working modes.
6) And detecting whether the power supply version supports setting of the main/standby working mode.
7) The feedback power supply version supports setting of a main and standby working mode.
8) And setting the main and standby working modes of the power supply module.
In this embodiment of the present application, it may be first detected whether the current version of the power supply control device supports setting of the active/standby operating mode, and if the current version of the power supply control device supports setting of the active/standby operating mode, the power supply control device sends an inquiry message to the power supply module, where the inquiry message is used to inquire whether the version of the power supply supports the active/standby operating mode, and then the power supply module may feed back to the power supply control device whether the setting condition of the active/standby operating mode is satisfied. If the power supply version meets the setting condition of the main/standby working mode, the power supply control device issues a setting instruction to the power supply module, and the power supply module is set to the main/standby working mode.
If the current version of the power supply control device does not support the setting of the main/standby working mode, the firmware of the current version of the power supply control device can be upgraded, so that the upgraded version of the power supply control device is the version supporting the setting of the main/standby working mode. It should be noted that, in this embodiment of the application, whether the version of the power supply control device supports the active/standby operating mode may be preconfigured, for example, a power supply control device higher than the V5.0 version may be preconfigured to support setting the active/standby operating mode.
Further, after the power module is in the active/standby operating mode, the power supply control device may feed back a message that the active/standby operating mode is successfully set to the delivery device, and may record an active/standby operating mode log of the power module, so that the relevant information may be queried when needed for subsequent operation and maintenance.
And a third stage: operation and maintenance phase
In this embodiment, the operation and maintenance device may have a function of querying the power supply control device in batches and setting the main/standby operating modes.
At this stage, two modes may be included, one being autonomous query and the other being automatic feedback.
(1) Autonomous query
The operation and maintenance device can issue a command for inquiring the main and standby working modes to the power supply control device, then the power supply control device can inquire the working mode of the power module, and feed back the inquiry result to the operation and maintenance device. And if the working mode of the power supply module is the main/standby working mode, finishing the query. If the working mode of the power module is not the main/standby working mode, the operation and maintenance device can issue a command for starting the setting function of the main/standby working mode to the power supply control device, and the power supply control device can set the working mode of the power module after receiving the command. The process of the setting can refer to the description in the delivery phase, and the description is not repeated here.
In practical application, after the power supply control device sets the power supply module to the active/standby working mode, the operation and maintenance device can confirm that the wiring mode of the power supply module of the server selected by the administrator has changed, at this moment, the operation and maintenance device can provide a display interface, and the display interface can enable the administrator to timely know that the server supports the working mode without the STS switch in the operation and maintenance process, so that the administrator can conveniently know the power supply mode of the server.
And when the power module is not in the main/standby working mode, the operation and maintenance device can provide an interface so that an administrator can select whether to enable the server to support the STS-free switch. If the administrator selects "yes," the operation and maintenance device may notify the power supply control device to configure the power supply module in the active/standby operating mode.
For example, the power supply control device may update the firmware version number of the power module so that the updated power version supports the active/standby operating mode. And the operation and maintenance device can prompt an administrator that the wiring mode of the power module of the server needs to be changed according to the updated firmware version number. And the updated firmware version number is used for indicating that the power supply module supports the main/standby working mode.
(2) Autonomous feedback
After the power supply control device sets the working mode of the power supply module to the active/standby mode in the delivery stage, the power supply control device can detect the working mode of the power supply module in real time, and then the power supply module can feed back the working mode of the power supply control device in real time. Therefore, if the working mode of the power supply module changes, the power supply control device can timely give an alarm to the operation and maintenance device so as to timely adjust the working mode of the power supply module. It can be understood that the operating mode of the power module changes, for example, the main power source 1 may be switched to the standby power source 2, or the main power source 1 may be switched to the load balancing power mode.
That is to say, in the embodiment of the present application, the power supply control device may provide an inquiry interface to the operation and maintenance device, and may also actively inquire and automatically feed back an alarm. And after the power supply control device sets the power supply module to be in the main/standby working mode, if the scene of power failure of the single-path power supply module or restarting of the server occurs, the main/standby working mode of the power supply module cannot be changed.
In addition, in the embodiment of the present application, since the backup power supply link is used as a hot backup, there is no load under normal conditions, and the current is very small, in a Data Center Infrastructure Management (DCIM) system, a circuit early warning value may be set for the backup power supply link. And if the current value of the standby power supply link is larger, pushing the alarm to the DCIM.
Further, in practical applications, a problem of an equipment failure or a link failure may occur, and then, when a failure or maintenance occurs, the influence on the working mode of the power module may be different, for example, in some scenarios, the active/standby working mode of the power may need to be reset. In different scenarios, the measures taken for the operating mode of the power supply module can be seen in table 1 below.
Table 1 working mode of power module under different scenes

Single power module failure Replacing power supply module and resetting main and standby power supply working modes
Power module software upgrade Two power supply modules are upgraded in turn, and after the upgrade is completed, the working modes of the main power supply and the standby power supply are set
According to the embodiment of the application, the working mode of the power supply module is set by combining software and hardware, the control strategy of the power supply module is controlled, STS is not needed, and therefore switching of the main link and the standby link is completed. According to the method, the construction cost of the data center is reduced, and meanwhile the reliability of link switching is improved. Compared with the scheme in the prior art, the STS cabinet is removed, the space in the machine room can be increased, and the cabinet discharging rate is improved. Meanwhile, an STS cabinet is removed, and the management strategies of linked planning, delivery, operation and maintenance are realized through an infrastructure L1 layer and a server soft and hard L2 layer, so that the delivery, operation and maintenance flow is simplified, and the labor cost can be reduced.
