Referring to fig. 2, fig. 2 is a flowchart of a power supply method provided in an embodiment of the present application. As an embodiment, the process shown in fig. 2 may be applied to a network device, such as a GPU server. The power supply structure provided in this embodiment is shown in fig. 3, and the network device at least includes a first power supply device 31, a second power supply device 32, a motherboard 33, and a power adapter board 34, where the first power supply device 31 is connected to the motherboard 33, in this embodiment, the first power supply device 31 may supply power to other hardware devices 35 on the network device through a voltage reduction device 37 on the motherboard 33, the second power supply device 32 is connected to the power adapter board 34, and the second power supply device 32 may supply power to a GPU36 on the motherboard through the power adapter board 34 outside the motherboard. The voltage of the first power source output by the first power source device 31 is P1, the voltage of the second power source output by the second power source device 32 is P2, the voltage of the power source input to the other hardware device 35 after the first power source is converted by the voltage reduction device 37 is P3, in a specific application, the value of P1 may be 12V, the value of P2 may be 48V/54V, and the value of P3 may be 5V/3.3V, which is the rated voltage of the power source required by the GPU.
For example, the voltage of the first power resource may be 12V, and the voltage of the second power resource may be 48V or 54V, and the other hardware devices in this embodiment may be hardware devices on the motherboard of the server other than the GPU device, such as devices of a BIOS, a CPU, a memory, an array card, a network card, and the like. It should be noted that before the first power source is provided to other hardware devices, the first power source needs to be further converted, for example, the first power source is further converted by the voltage reducing device 37, and the conversion process may refer to related technologies, and is not described herein again.
Optionally, in this embodiment, the first power supply device includes at least one first power supply unit PSU (power supply unit), and the second power supply device includes at least one second PSU. Optionally, if the first power supply device includes a plurality of first PSUs, the plurality of first PSUs may be connected in series or in parallel, and similarly, if the second power supply device includes a plurality of second PSUs, the plurality of second PSUs may also be connected in series or in parallel.
As shown in fig. 2, the flow of the power supply method provided in this embodiment may include the following steps:
As an embodiment, in order to prevent the main board from being directly connected to the current of the normal power supply after the network Device is powered on, the main board and other hardware devices on the main board are damaged due to the short circuit of the current caused by the damage of some hardware devices on the main board, when the network Device is powered on, the main board will start the protection mechanism, and only the micro-current that can start the hardware Logic CPLD (Complex Programmable Logic Device) for self-test preset in the main board is connected, and the micro-current is input to each hardware Device on the main board at the same time. The hardware device on the motherboard may refer to a CPU chip, a memory card, a network card, and the like installed on the motherboard.
After the hardware logic CPLD is started, the hardware logic CPLD may start to send a detection message to various hardware devices on the motherboard, and when a response of the hardware device is received, it may be determined that the hardware device in response is on bit and is not damaged, and then the flag bit corresponding to the hardware device in response recorded in the register on the motherboard is updated. And the flag bit corresponding to each hardware device recorded by the register is used for identifying whether the hardware device is in place.
After the hardware logic CPID traverses and detects various hardware devices on the main board once, if it is determined that hardware devices such as a CPU chip, a memory chip, and a BIOS chip, which are required to form a basic system on the main board, are all in place, the main board can be controlled to open a circuit for accessing a current for normal power supply, that is, the first power supply device is controlled to input the first power supply resource to the main board.
In this embodiment of the present application, after the motherboard receives the first power resource, the motherboard may start to supply power to other hardware devices installed on the motherboard, such as a CPU, a memory, a network card, and an array card, except for a GPU, and the power supply process may also supply power to a CPU chip on the motherboard and a BIOS chip carrying a BIOS program, so that the BIOS on the motherboard may be started. After the BIOS starts running, a self-test program of the BIOS is started to be executed, where the self-test program is used to detect whether a hardware device (such as a PCIE (peripheral component interconnect express) device) on a motherboard is in place, and to test whether the hardware device in place can work normally. The specific detection process of the BIOS firmware performing the self-test can refer to the related art, and is not described in detail herein.
It should be noted that, the first power supply apparatus in the foregoing embodiment is configured to output the first power supply resource, where the voltage of the first power supply resource is a first specified voltage, where the first specified voltage may refer to a voltage of a power supply resource input to a motherboard in the related art, for example, the first specified voltage may be 12V, and the application is not limited thereto.
In this embodiment of the present application, the second power supply device is configured to output a second power supply resource, where a voltage of the second power supply resource is a second specified voltage, and the second specified voltage is a rated voltage of a power supply required by a GPU in this apparatus, and values of the first specified voltage and the second specified voltage are different in this embodiment of the present application.
As an embodiment, after the motherboard is powered up in step 201 and the self-test program of the BIOS is started, since the GPU in this embodiment also belongs to the PCIE device, it can be known whether the GPU on the device is on site and whether the GPU can work normally through the self-test of the BIOS firmware.
Optionally, in this embodiment, when the BIOS detects whether the GPU on the device is in place and whether the GPU can normally work, since the in-place situation of the GPU on the motherboard is detected based on the hardware logic CPID and the flag bit corresponding to the GPU recorded in the register is updated, in this embodiment, whether the GPU is in place can be determined by accessing the flag bit corresponding to the GPU recorded in the register by the BIOS. In this embodiment of the present application, if the accessed value of the flag bit is a first value, it may be determined that the GPU corresponding to the flag bit is in place, and if the value of the flag bit is a second value, it may be determined that the GPU corresponding to the flag bit is not in place.
For example, the GPU flag bit is usually a bit, and when the value of the bit is 1 (i.e., the first value is 1), it indicates that the GPU in the server is in place, and when the value of the bit is 0 (i.e., the second value is 0), it indicates that the CPU in the server is not in place.
Further, as an embodiment, when it is detected that the GPU is in place in the device, the BIOS may be triggered to issue a power resource control instruction through a program newly added in the BIOS in the embodiment, so as to instruct the GPU to start a circuit accessing a second power resource through the power resource control instruction, so that the second power device inputs the second power resource to the power adapter board. In this embodiment, the power resource control instruction may be implemented by an IPMI (Intelligent Platform Management Interface) protocol.
Thus, the flow shown in fig. 2 is completed.
As can be seen from the process shown in fig. 2, in this embodiment, a first power supply device for outputting a first power supply resource and a second power supply device for outputting a second power supply resource are arranged in a network device, so that when power needs to be supplied to hardware on the device, the first power supply device is used to supply power to a motherboard, and when it is detected that a GPU on the device is in place, the second power supply device is used to supply power to the GPU, thereby forming two paths of power supply circuits without overlapping. In this embodiment, the second power supply device that supplies power to the GPU may directly output the second power supply resource that meets the power supply requirement of the GPU, and thus, it is not necessary to use a boosting device or the like to convert the power supply resource that is supplied to the GPU, which improves the utilization rate of the power supply resource that is supplied to the GPU.
The above examples are merely for convenience of understanding, and the embodiments of the present application are not particularly limited.
An embodiment of another power supply method provided by the present application is described below with reference to fig. 4 and 5, where a power supply structure provided in this embodiment is as shown in fig. 5, and the network device is composed of at least a first power supply device 51, a second power supply device 52, a hardware switch 53, a voltage conversion device 54, a main board 55, and a power adapter board 56. The first power supply device 51 is connected to the main board 55, and in this embodiment, the first power supply device 51 may supply power to other hardware devices 58 on the device through a voltage reduction device 59 on the main board 55; the second power supply device 52 is connected with the voltage conversion device 54 through a hardware switch 53, and the second power supply device 52 can supply power to the GPU57 on the motherboard through the hardware switch 53 and the power adapter board 56 outside the motherboard; the second power supply device 52 and the motherboard 55 are further connected to the voltage conversion device 54 through the hardware switch 53, and the second power supply device 52 can supply power to the motherboard 55 on the device through the hardware switch 53 and the voltage conversion device 54, so that the motherboard 55 supplies power to other hardware devices 58 on the motherboard. The voltage of the first power source output by the first power source device 51 is P1, the voltage of the second power source output by the second power source device 52 is P2, the voltage of the power source input to the other hardware device 58 after the first power source is converted by the voltage reduction device 59 is P3, in a specific application, the value of P1 may be 12V, the value of P2 may be 48V/54V, and the value of P3 may be 5V/3.3V, which is the rated voltage of the power source required by the GPU.
As shown in fig. 4, the flow of the power supply method provided in this embodiment may include the following steps:
In this embodiment, reference may be made to the above description of the method embodiment shown in fig. 2 for controlling the first power supply device to input the first power supply resource to the motherboard, and details are not repeated here.
In this embodiment, a hardware switch is added between the second power supply device and the power adapter board, and when it is detected that the GPU on the device is in place, the BIOS on the device may control the hardware switch to be connected to the power adapter board and to be disconnected from the power conversion device, thereby implementing input of the second power supply resource to the power adapter board.
In this embodiment, in order to fully utilize the power source resource in the second power source device, when it is detected that the GPU on the device is not in place, the BIOS on the device may control the hardware switch to be connected to the power conversion device and to be disconnected from the power adapter board, so as to input the second power source resource to the power conversion device, and further, the voltage conversion device converts the second specified voltage corresponding to the second power source resource into the first specified voltage.
It should be noted that, the control hardware switch is communicated with the power conversion device or the power adapter board, and may be implemented by a power resource control instruction issued by the BIOS, where the power resource control instruction may be an IPMI instruction conforming to an IPMI protocol.
The flow shown in fig. 4 is completed.
As can be seen from the flow shown in fig. 4, in this embodiment, a first power supply device for outputting a first power supply resource and a second power supply device for outputting a second power supply resource are arranged in a network device, so that when power needs to be supplied to hardware on the device, the first power supply device is used to supply power to a motherboard, and when it is detected that a GPU on the device is in place, the second power supply device is used to supply power to the GPU, thereby forming two paths of power supply circuits without overlapping. In this embodiment, no main board is needed to be used for supplying power to the GPU, and the second power supply device can directly output the second power supply resource meeting the power supply requirement of the GPU, so that the power supply resource supplied to the GPU does not need to be converted by using a boosting device and the like, and the utilization rate of the power supply resource supplied to the GPU is improved.
In addition, by adding a hardware switch and a power conversion device, when the GPU is not in place, the second power resource of the second power device is fully used for supplying power to the motherboard, and because the GPU on the network device is generally in the in-place state in the actual application process, the power resource consumed by the power conversion device is less than the power resource consumed by the boost device in the related art, so that the utilization rate of the power resource supplied to the GPU is also improved in the embodiment compared with the related art.
