In order to better understand the technical solutions in the present application, some related technologies referred to herein will be explained first.

CPU (central processing unit): the central processing unit, as the operation and control core of the computer system, is the final execution unit for information processing and program operation.

GPU (graphics processing unit): the graphics processor, also called a display core, a visual processor, and a display chip, is a microprocessor dedicated to image and graphics related operations on personal computers, workstations, game machines, and some mobile devices (e.g., tablet computers, smart phones, etc.).

PSU (power supply unit): the power module belongs to an electric energy conversion power supply and is responsible for converting standard alternating current into low-voltage stable direct current for other components in the computing equipment.

PCB (printed circuit board): a printed circuit board, also called a printed circuit board, is a support for electronic components and is a carrier for electrical interconnection of electronic components.

Veneer: a functional module formed by a single PCB.

A backplane (backplane) for interconnecting the circuit boards of the single boards.

Copper bar (copper busbar): generally referred to as copper bus bars, are the conductive material of the conductors used in power distribution installations.

Power cable: are wires that carry current and are typically used for point-to-point current transfer.

Generally, before a computing device is put into use, modules and devices need to be configured according to actual working requirements, so that the performance of the computing device meets working requirements. For example, for a cloud computing server, since high processing and computing capabilities are required, key devices such as a higher-performance CPU and a GPU are required to be configured, and a plurality of functional modules such as fans (heat dissipation devices) and hard disks are also required to be configured to be connected to a motherboard to ensure operations of the key devices, and then the motherboard obtains electric energy from a PSU connected thereto to supply power.

As a specific example, fig. 1 shows a hardware structure diagram of a connection module and a device on a motherboard in a server. As shown in fig. 1, in the server 10, a hard disk backplane 15 (i.e., a backplane carrying a hard disk), a fan 16, and other functional modules or components are connected to a motherboard 11 through a power line 14, and the motherboard 11 is further connected to a plurality of PSUs 13 through a plurality of power connectors 12 to obtain sufficient power to power the connected modules and devices.

However, this power supply method has some disadvantages: on one hand, with the performance improvement of key devices and the like, the power consumption to be carried by the main board 11 is continuously increased, which leads to the continuous increase of the current requirements on the devices such as the power connector 12 and the like, and then the design of the PCB board of the main board 11 is increasingly complex, the number of the layers of the PCB board is increased, and the cost is increased. On the other hand, the manner that the motherboard uniformly supplies power by using the PSU13 cannot realize independent control of powering on and powering off and protection of the computing device module, and in the configuration process of the computing device, the specifications of the motherboard, the module and the like, such as self models and interfaces, are fixed, the configuration requirement and the uniform power supply requirement are both considered, and the configuration difficulty is high.

In order to meet the requirement of high power consumption of computing equipment, and meanwhile, realize flexible configuration of a power supply mode and reduce cost, the embodiment of the application provides the power supply backboard, the computing device and the computing equipment.

To facilitate understanding of the technical solution of the present application, first, a power backplane provided in an embodiment of the present application is described below.

Fig. 2 is a schematic structural diagram of a power backplane provided in an embodiment of the present application. It is understood that the power backplane may be deployed in any device or apparatus having computing and processing capabilities, such as, but not limited to, a desktop computer, a workstation, a laptop computer, a personal digital assistant, a server, a mainframe, and the like.

As shown in FIG. 2, the power backplane 20 includes a backplane 21, wherein M first connectors 22 and N second connectors 23 are disposed on the backplane 21, any one of the second connectors 23 is electrically connected to at least one of the first connectors 22, M, N is greater than or equal to 1, M, and N is a positive integer. Wherein:

each first connector 22 may be configured to connect to the power module PSU30, and each second connector 23 may be configured to connect to at least one functional board 40, so that each functional board 40 obtains power through the power module PSU30 connected to the corresponding first connector 22. The functional board 40 is a board for implementing a corresponding function, and may include, for example, a motherboard, an IO board, a fan board, a hard disk backplane, a Riser card, and the like, but is not limited thereto.

In this embodiment, the backplane 21 is electrically connected to the second connector 23 through the first connector 22, so that the electric energy provided by the PSU30 can be input to each functional board 40 connected to the second connector 23 through the first connector 22 and the second connector 23, thereby implementing independent power supply to each functional board, and compared with a unified power supply mode through a motherboard, the present embodiment utilizes the independent power supply mode of the power backplane 20 to facilitate reducing the design complexity of the circuit board and reduce the cost.

Illustratively, as shown with reference to fig. 2, each first connector 22 may be used to connect to one power module PSU30.

In some specific examples, the first connector 22 is a connector for connecting the power module PSU30 to the power backplane 20, and the type and the specification of the first connector may be the same or different. In this way, the power backplane 20 may access PSUs 30 of corresponding number, type and specification through the first connectors 22 of different numbers, types or specifications, thereby facilitating flexible configuration of PSUs 30 of corresponding specification and number according to power consumption of all function boards 40 connected to the power backplane 20.

For example, 5 first connectors 22 are disposed on the back plate 21, each first connector 22 is a 9Pin rectangular connector, wherein the current capacities of 4 first connectors 22 are the same, the current capacities are all 100A, and the current capacities of the remaining 1 first connectors 22 are 200A. When the total power consumption of all the functional boards 40 connected by the back plane 21 through the second connector 23 is about 4000 watts (W), four PSUs 30 with rated power of 1050W can be respectively connected to the 4 first connectors 22 with the same current-carrying capacity on the back plane 21, so as to meet the power requirements of the functional boards 40.

It is understood that in the present embodiment, each first connector 22 on the backplane 21 may be connected to one PSU30, or the total number of the first connectors 22 may be greater than the total number of connected PSUs 30, i.e., all of the first connectors 22 on the backplane 21 may not be used. Thus, a greater number of first connectors 22 on the backplane 21 can be connected to the power module according to actual requirements, which is suitable for configuration of multiple computer device models (different connectors and different power consumptions), covers a wider range of power supply requirements, and improves the versatility of the power backplane 20.

In some specific examples, a plurality of first connectors 22 may be connected in parallel to increase the total output power or total current in response to being connected to the PSU30, which may be sufficient to meet various different energy requirements. For example, 4 PSUs 30 are connected to the power backplane 20 by connecting 4 first connectors 22 of the same type in parallel, and the total power provided by the power backplane 20 is the sum of the powers of the 4 PSUs 30.

For example, after the plurality of first connectors 22 are correspondingly connected to the PSU30, the plurality of second connectors 23 may be connected to the plurality of first connectors as an integrated power supply module. Alternatively, one first connector 22 may be directly connected to one or more second connectors 23.

In some specific examples, referring to fig. 3A, all connectors (22, 23) on the power backplane 20 are provided with a power terminal V + and a ground terminal GND. The power terminals V + of all the first connectors 22 on the power backplane 20 are correspondingly connected to the power terminals V + of the second connectors 23, and the ground terminals GND of all the first connectors 22 are correspondingly connected to the ground terminals GND of the second connectors 23. In this way, any one of the second connectors 23 can obtain power from the plurality of PSUs 30 based on the plurality of first connectors 22, which is beneficial to improving the reliability of power supply to the function board 40 connected to the second connector 23.

In some specific examples, the first connector 22 may be a connector of large current capacity sufficient to support a PSU30 with an output voltage of 12V and a power rating of 3000W.

In addition, for example, when the number of the second connectors 23 on the power backplane 20 is multiple, that is, N is greater than or equal to 2, the N second connectors 23 may include at least two types and/or specifications of connectors, so as to be capable of correspondingly accessing different function boards 40 respectively. In this way, when configuring the computing device, after determining the function module according to the configuration requirement of the corresponding model, the second connector 23 of the power backplane 20 is type-selected according to the power consumption of different function boards, so that the function board 40 can be flexibly accessed to the corresponding second connector 23.

For example, referring to fig. 3B, there are 3 cable connectors 23a in 5 second connectors 23 disposed on the power backplane 20, and each cable connector 23a can be connected to some functional boards 40 (e.g. fan boards, riser cards) with low power consumption (e.g. power consumption lower than 1000W) through the power cable 24. The remaining 2 second connectors 23 are copper bar retainers 23b, and each copper bar retainer 23b can be connected to some functional single boards 40 (such as a main board and an IO board) with large power consumption (such as power consumption exceeding 2000W) through a copper bar 25.

For example, in the present embodiment, the second connector 23 for connecting the higher power consumption function board may be a connector supporting a current of 12V ≦ 300A, such as a Copper bar connector (also referred to as "Copper bar connector" or "Copper bar fixing structure"), a Powerblade power connector, a gold finger (gold finger), a pin (power pin), an OT terminal, or a high current DL connector, but is not limited thereto. In addition, the second connector 23 connecting the single board with smaller Power consumption can support the connector of 12V, 80A or less current, such as fast plug terminal (EASY Power, HVDC, etc.), PP terminal, low current DL connector, etc., but not limited thereto.

It can be understood that, in this embodiment, the aforementioned N second connectors 23 are electrically connected to the aforementioned M first connectors 22 through the back plate 21 of the power supply back plate 20. The back plate 21 may have a certain thickness as a supporting member for carrying a plurality of connectors, and a corresponding connection circuit is disposed to configure the M first connectors 22 and the N second connectors 23 into different connection structures, for example, the M first connectors 22 are connected in parallel, or one first connector 22 is directly connected to one second connector 23, and the like, which is not described herein again.

The foregoing describes a structure of a power backplane according to an embodiment of the present application with reference to the accompanying drawings, and then a computing device according to an embodiment of the present application is described based on the foregoing description. It will be appreciated that the computing device is set forth in the foregoing description, and that some or all of the content of the computing device can be found in the description above.

Referring to fig. 4, fig. 4 is a schematic diagram of a hardware structure of a computing device according to an embodiment of the present disclosure. It will be appreciated that the computing device may be deployed in any device or apparatus having computing or processing capabilities. As shown in FIG. 4, the computing device 400 may include the power backplane 20 shown in FIG. 2, and in addition, the computing device 400 further includes K functional boards 40, where K ≧ 1, and K is a positive integer. Wherein:

each functional board 40 is provided with a corresponding functional circuit and at least one third connector 41 accessing the functional circuit. The third connector 41 on each functional board 40 is configured to be connected to at least one second connector 23 on the power backplane 20, so that, based on the connection relationship between the second connector 23 on the power backplane 20 and the power module PSU30, each functional board 40 can obtain electric energy from the corresponding power module PSU30, and input the functional circuit accessed by the third connector 41, so that after the functional circuit of each functional board 40 obtains the electric energy, the corresponding function of the functional board 40 in which the functional board 40 is located is implemented.

In this embodiment, the functional board 40 is a board for implementing a corresponding function, and as shown in fig. 5, the K functional boards 40 may be functional boards (40a, 40b,40c,40d, and 40e) with different functions, and may be divided into a main board 40a and a slave functional board (40b, 40c,40d, and 40e) according to a logic control relationship.

Illustratively, the motherboard 40a, i.e., a main board (main board), a system board (system board), a motherboard (mother board) or a logic board, constitutes a center or main circuit board of the computing device, and is provided with a main circuit system constituting a computer, which generally includes processors such as a CPU, a GPU and a BIOS chip, and further includes elements such as an I/O control chip, a memory slot, an AGP slot, a PCI slot, an IDE interface, a key and board control switch interface, an expansion slot, a serial port and a parallel port on the edge of the motherboard, a PS/2 interface, and a dc power supply connector (i.e., the third connector 41 b) of the motherboard.

The IO board 40b is a functional module for analog-to-digital (a/D) signal conversion and digital-to-analog (D/a) signal conversion, the core of the IO board 40b is an AD and DA conversion chip, and the converted signal communicates with the CPU of the main board 40a through a communication chip on the board. The fan board 40c is a single board bearing a fan, the hard disk backplane 40d is a single board bearing a hard disk, and the Riser card 40e is a card for transferring and expanding slots.

In this embodiment, the functional boards (40a, 40b,40c,40d, 40e) with different functions are isolated from each other, that is, each of the functional boards (40b, 40c,40d, 40e) is independent from the motherboard 40a, so that each of the functional boards (40b, 40c,40d, 40e) can be connected to the power backplane 20 respectively on the premise that the logical control relationship with the motherboard 40a is not changed, and each of the functional boards (40a, 40b,40c,40d, 40e) can be connected to the power backplane 20 respectively, so as to achieve modularized independent power supply, reduce the load power consumption of the motherboard 40a, solve the problem of excessive power consumption of the motherboard power supply, reduce the design complexity of the motherboard PCB, reduce the number of layers of the motherboard, and further facilitate the reduction of the motherboard cost.

Specifically, as shown in fig. 4, each functional board is provided with a third connector 41, and the third connector 41 is used for being correspondingly connected to the second connector 23 on the power backplane 20, so that after receiving a power-on signal of a system (i.e., a complete system where the board is located), the PSU30 of the power backplane 20 can transmit electric energy to the designated functional board 40 through the corresponding second connector 23, so that the functional board 40 is powered on to operate and execute its function.

In some specific examples, each functional board 40 is provided with an onboard power supply, a power input terminal of the onboard power supply is connected to the third connector 40 on the respective board to obtain power from the PSU30 on the power backplane 20, and a power output terminal of the onboard power supply is connected to the functional circuit of the board to supply the obtained power to devices in the functional circuit, such as the onboard power supply on the fan board 40c to supply power to each fan and other devices on the board, the onboard power supply on the hard disk backplane 40d to supply power to each hard disk and other devices on the backplane, and so on.

For example, between the third connector on each functional single board 40 and the on-board power supply, a power supply control unit and a power supply protection unit may be further provided, wherein the power supply control unit may be configured to connect or disconnect a circuit between the third connector and the on-board power supply, so as to implement separate power-on and power-off control of the functional circuit of the single board. The power supply protection unit can be used for power supply protection of an onboard power supply of the single board.

In some possible implementations, as shown in fig. 6, the power control unit and the power protection unit of each functional board (40a, 40b,40c,40d, 40e) may be integrated into one functional module, i.e., the control protection module 42, so as to facilitate the integration and miniaturization design of the computing apparatus 400. For example, fig. 7 shows a schematic diagram of a control protection module, and as shown in fig. 7, the control protection module 42 may include a logic device 421 and a start-up chip 422. The power input end of the slow start chip 422 is connected to the third connector 41 on the board, and the power output end is connected to the on-board power supply 43 on the board. One signal output end of the logic device 421 is connected to the enable end EN of the slow start chip 422 through the switching device D, and one signal input end of the logic device 421 is connected to one signal output end of the slow start chip 422. In this example, the logic device 421 may be a CPLD or other logic control chip, but is not limited thereto. It should be understood that, in this example, the control protection module 42 on any functional board 40 may adopt the circuit structure shown in fig. 7.

In the process of performing separate power-on and power-off control, if the logic device 421 of the functional board 40 receives a power-on signal sent by a system (i.e., a complete system), the logic device 421 controls an EN signal or other signals of the slow-start chip 422, for example, the signal is at a high level, and transmits the signal to the enable end EN of the slow-start chip 422, and then controls the slow-start chip 422 to enable, and starts power supply to the onboard power supply 43 on the functional board 40. If the logic device 421 of the functional board 40 receives a power-down signal sent by the system (i.e., the whole system), the logic device 421 controls the EN signal or other signals of the slow start chip 422, for example, to make the signals at a low level, and then the slow start chip 422 stops transmitting the electric energy to the on-board power supply 43 after receiving the signals.

When the individual power supply protection is performed, the logic device 421 monitors the state signal (for example, a signal indicating whether power-on is normal) sent by the slow start chip 422, so as to monitor the working state of the on-board power supply 43, and when the logic device 421 monitors that the state signal sent by the slow start chip 422 is abnormal, the EN signal can instruct the slow start chip 422 to cut off the power supply to the on-board power supply 43. Thus, when a certain board 40 has an abnormal power supply (e.g. an abnormal on-board power supply 43), the power supply of the board 40 can be cut off individually, and other boards in the whole machine are not affected by the current abnormal power supply board 40.

Thus, the computing device 400 in this embodiment can independently supply power to each functional module 40 based on the power backplane 20, and can make protection and power-up and power-down control of each board 40 independent of the control protection module of the motherboard 40a, and the system can independently issue a command to each board logic device 421, so that the logic device 421 can realize independent power-up and power-down control and module-level power supply protection of each functional board 40 through signals such as power-up and power-down of the system and current power supply state judgment of each board 40.

For example, in order to ensure the reliability of the electrical connection between each functional board 40 and the power backplane 20, the type or specification of the third connector 41 on each functional board 40 and the second connector on the power backplane 20 to which it is connected may be the same.

For example, as shown in fig. 5, for the low Power consumption boards such as the fan board 40c, the hard disk backplane 40d, and the Riser card 40e, the third connector 41a disposed thereon and the second connector 23a on the Power backplane 20 connected thereto may be connectors with smaller current capacity, such as fast plug terminals (EASY Power, HVDC, etc.), PP terminals, low current DL connectors, etc., but are not limited thereto. Correspondingly, for the single boards with large power consumption, such as the main board 40a and the IO board 40b, the third connector 41b disposed thereon and the second connector 23b connected to the power backplane 20 may be connectors with large current-carrying capacity, such as a copper bar connector, a Powerblade power connector, a gold finger, a pin, an OT terminal, or a large current DL connector, but are not limited thereto.

As a specific example, the third connector 41a of the low power consumption board may be connected to the second connector 23a with a small current capacity on the power backplane 20 through a power cable with a relatively small current capacity in a one-to-one correspondence manner, and the third connector (such as a copper bar connector) 41b on the high power consumption board may be connected to the second connector 23b with a large current capacity on the power backplane 20 through a wire with a large current capacity such as a copper bar.

It is understood that, in this example, the third connector 41a with small current capacity and the third connector 41b with large current capacity are of different types of the third connector 41, and the second connector 23a with small current capacity and the third connector 23b with large current capacity are of different types of the second connector 23.

Furthermore, for example, the third connector 41 on each functional board 40 may have multiple specifications or types, so as to selectively connect to a connector on the power backplane 20 that matches the power consumption of the functional board according to the power consumption of the functional board. In addition, the third connectors 41 on a plurality of low-power consumption boards such as fan boards can be kept consistent, so that different function boards 40 can also supply power through the same power cable when different machine types are configured, configuration complexity is reduced, and the function of flexibly configuring the computing device is ensured.

For example, referring to the flowchart shown in fig. 8, when configuring a computing apparatus (i.e. configuring a computing device), according to an actual working scenario, first determine the type and the number of the required functional boards 40, after determining the type, the number, and the like of these functional boards 40, evaluate the energy consumption required by them, and then configure the corresponding number and performance of connectors and PSUs on the power backplane 20, thereby obtaining the computing apparatus in this embodiment. For example, for the functional board 40 with power consumption lower than 2000W, the cable and the small ampacity connector are selected for power supply, and for the functional board 40 with power consumption higher than 2000W, the copper bar and the large ampacity connector are selected for power supply. Then, the number of corresponding connectors and PSUs is determined, and a power backplane, related control protection circuits and the like are designed.

For example, when 4 functional boards 40, which are a motherboard, a fan board, a hard disk backplane, and a RISER card, are required to be configured in the server, and the RISER card is an optional configuration module, first, through analyzing the performance of each functional board 40, if it is known that the power consumption of the 5 functional boards 40 in the complete server is 4000W, the number of PSUs required by the complete server is evaluated, for example, 4 PSUs 30 with the same specification and rated power of 1050W are correspondingly configured to meet the requirement.

Wherein, the consumption of mainboard is more than 2000W, consequently can be to its power supply through the copper bar, like this, copper bar connector on the mainboard can be connected to the copper bar fixer on the power backplate 20 through the copper bar on, the copper bar fixer is used for fixing copper bar and power backplate 20, guarantee the current capacity of power backplate 20 and mainboard, for example, the copper bar fixer can include the copper bar contact, can fix the copper bar on the copper bar contact of power backplate 20 through the fix with screw, or welded form, can satisfy more than the current capacity 200A, realize the electric connection between the board. In addition, the power consumption of the fan board, the hard disk backplane and the RISR card is less than 1000W, and power can be supplied through the power cable, so that the power backplane 20 can be configured with some terminals (i.e. second connectors) with small current capacity, if the current capacity is satisfied 80A, and the third connectors 41 on the fan board, the hard disk backplane and the RISR card can be respectively connected to the second connectors on the power backplane 20 through the power cable.

In this embodiment, the computing device can provide a flexibly configured hybrid power supply scheme for the combination of different model single boards by using a copper bar, a power cable and the like based on the power backplane 20, and support power supply to a plurality of single boards with different power consumption requirements, thereby realizing compatibility of different model power supply schemes.
