Description

Technical Field

[0001] This application belongs to the field of computer technology, and particularly relates to an OCP card configuration method and device. Background Art

[0002] Open Compute Project (OCP) cards, as standardized modules, are widely used in high-performance expansion scenarios of X86 servers.

[0003] Currently, in an X86 server, a central processing unit (CPU) is interconnected with an OCP connection slot through high-speed peripheral component interconnect express (PCIe) bus resources.

[0004] However, an OCP connection slot usually has pin resources that can access PCIe X16. Existing OCP function cards, such as OCP network interface cards (NICs), only occupy PCIe x8 or x4 channel bandwidth, resulting in idle remaining pin resources in the OCP connection slot and PCIe channel resources provided by the CPU, causing a waste rate of hardware resources. Moreover, existing OCP connection slots cannot be compatible with diverse function cards and cannot meet diverse requirements through a single physical interface. Summary of the Invention

[0049] To facilitate the understanding of the embodiments of this application, the relevant concepts involved in this application are first explained.

[0050] 1. Platform Controller Hub (PCH)

[0051] The PCH is responsible for coordinating the communication between the CPU and peripheral devices. Its main functions include I / O control, which is also to manage the connection and data transmission of high-speed devices such as USB, SATA, and PCIe through the high-speed I / O bus (HSIO) interface.

[0052] 2. OCP connection slot

[0053] The OCP connection slot is a modular interface that follows the Open Compute Project standard and is used to insert OCP cards.

[0054] 3. Control the baseboard management controller (BMC)

[0055] The BMC is an independent management subsystem in the server and has the ability to obtain relevant information of the OCP card from the OCP connection slot.

[0056] The OCP card configuration method provided in the embodiments of the present application can be applied to servers, and can also be applied to terminal devices such as mobile phones, tablet computers, wearable devices, vehicle-mounted devices, augmented reality (AR) / virtual reality (VR) devices, laptop computers, ultra-mobile personal computers (UMPCs), netbooks, and personal digital assistants (PDAs). The embodiments of the present application do not impose any restrictions on the specific types of terminal devices.

[0057] The present application proposes an OCP card configuration method, device, server, and computer-readable storage medium. The method is applicable to scenarios where the OCP connection slot can install a general OCP card (the second OCP card in the following text) or a multi-functional OCP card (the first OCP card in the following text), and the CPU in the server can be configured according to different types of OCP cards.

[0058] For example, the general OCP card can be a memory card, a network card, an acceleration card, etc.

[0059] For example, the multi-functional OCP card can include at least two sub-OCP cards, and any one of the sub-OCP cards can be a memory card, a network card, an acceleration card, etc.

[0060] Among them, when the OCP card configuration method of the present application is executed by the server, as Figure 1 shown, the server includes a CPU, a PCH, an OCP connection slot, and a BMC. The CPU is respectively connected to the PCH and the BMC, the PCH is respectively connected to the OCP connection slot and the BMC, and the BMC is connected to the OCP connection slot. The BMC can communicate with the OCP connection slot through the I2C protocol or through other protocols, such as a software-simulated serial port protocol. The present application does not make specific limitations on this.

[0061] When the CPU controls the PCH to determine that the OCP card connected in the OCP connection slot is a multi-functional OCP card, the CPU can control the BMC to obtain the type of each sub-OCP card in the multi-functional OCP card from the OCP connection slot. Thus, the CPU can configure the channel group of the PCH corresponding to the pins of each sub-OCP card into the mode corresponding to the type of each sub-OCP card. Therefore, by connecting a multi-functional OCP card including at least two sub-OCP cards in one OCP connection slot, physical space can be saved, resource waste can be avoided, and relevant configurations can be automatically performed based on the type of each sub-OCP card. The diverse requirements for the use of OCP cards can be achieved through a single interface, significantly improving the compatibility and flexibility of the server in using OCP cards.

[0062] For example, the multi-functional OCP card includes two sub-OCP cards, namely the first sub-OCP card and the second sub-OCP card. When the type of the first sub-OCP card is a high-performance hardware expansion card, the channel group of the PCH can be configured into the PCIe mode. When the type of the second sub-OCP card is a memory card, the channel group of the PCH can be configured into the SATA mode.

[0063] Among them, as Figure 2 shown is the multi-functional OCP card, and the physical size of the multi-functional OCP card is the same as that of the general OCP card. Figure 2 (a) in Figure 2 can be the first sub-OCP card. The first sub-OCP card and the second sub-OCP card in Figure 2 (b) are connected through pins (which can also be called gold fingers). The first sub-OCP card can transmit power signals and GPIO signals (ID signals), etc. to the second sub-OCP card.

[0064] (c) in Figure 3 and Figure 4 can be the second sub-OCP card. The first sub-OCP card can be a network card, and the second sub-OCP card can be an M.2 memory card or a USB expansion interface card.

[0064] In addition, the OCP connection slot adopts the OCP specification type of 168Pin 4C+. The pin definition table of the OCP connection slot can be shown in Table 1, including the pins on side A and side B. The circuit schematic diagram of the general 168Pin OCP card is as Figure 3 and Figure 4 shown.

[0065] Table 1 Pin Definition Table

[0066]

[0067]

[0068]

[0069] Among them, the general OCP card includes the pins in four regions of OCP 1C, OCP 2C, OCP 3C, and OCP 4C. The general OCP card has a function. Depending on the data bandwidth of its implemented function, the number of pins required by the OCP card is different. When the general OCP card uses high data bandwidth, there are pins of OCP 1C, OCP 2C, OCP 3C, and OCP 4C on it (a total of 168 pins). When the general OCP card uses low data bandwidth, there are pins of OCP 1C, OCP 2C, and OCP 3C on it (a total of 112 pins). Combining Table 1, and Figure 3 and Figure 4 the circuit diagram of the general OCP card shown, it can be seen that:

[0070] OCP_A1 to OCP_A14 and OCP_B1 to OCP_B14 are the pins of OCP 1C, corresponding to Figure 4 CA1 to CA14 and CB1 to CB14 in

[0071] A1 to A28 and B1 to B28 are the pins of OCP 2C, corresponding to Figure 3 A1 to A28 and B1 to B28 in

[0072] A29 to A42 and B29 to B42 are the pins of OCP 3C, corresponding to Figure 3 A29 to A42 and B29 to B42 in

[0073] A43 to A70 and B43 to B70 are the pins of OCP 4C, corresponding to Figure 4 A43 to A70 and B43 to B70 in

[0074] Among them, there are two pins of SLOT_ID, OCP_B7 and OCP_A6, on OCP 1C for determining the type of the OCP card.

[0075] Among them, the PCH includes a high-speed I / O bus HSIO (high-speed input / output, HSIO) and a general-purpose input / output interface (general purpose input / output, GPIO). HSIO includes 16 channels from PCIe0 to PCIe15. The HSIO in the PCH includes, but is not limited to, three functions: PCIe, SATA, and USB. This application does not make specific limitations on this. That is, the embodiments of this application can be applicable to multiple models of PCH, and other functions (such as SAS function, I3C function, etc.) that can be provided in other models of PCH.

[0076] Among them, the first OCP card includes, but is not limited to, an OCP interface circuit designed according to the current OCP 168Pin specification. This application does not make specific limitations on this. Below, taking the example that there are pins of OCP 1C, OCP 2C, and OCP 3C (a total of 112Pin) on the first sub - OCP card and there are pins of OCP 4C (a total of 56Pin) on the second sub - OCP card for illustration. The first sub - OCP card and the second sub - OCP card each have one function, and there are a total of two functions.

[0077] As Figure 5 shown in the circuit diagram of the first OCP card, PCIe8 - PCIe15 in the HSIO of the PCH are correspondingly connected to 2C (the range of the 2C area is A1 - A28 and B1 - B28) and 3C (the range of 3C is A29 - A42 and B29 - B42) of the first OCP card. PCIe0 - PCIe7 in the PCH HSIO are correspondingly connected to 4C (the range of 4C is A43 - A70 and B43 - B70) of the first OCP card.

[0078] As Figure 6 shown in the circuit diagram of the first OCP card, the PCH can be connected to the SLOT_ID pin of the OCP connection slot through two GPIOs ( Figure 6 GPP_A23 and GPP_A22 in it) to obtain GPIO signals. The PCH can also be connected to the SLOT_ID pin of the OCP connection slot through other functional pins. This application does not make specific limitations on this. In addition, when the PCH is connected to the OCP connection slot through two GPIOs, it can be connected to the SLOT_ID pin of the OCP connection slot through two GPIOs, or the two GPIOs can also be connected to other undefined pins of the OCP connection slot. This application does not make specific limitations on this. The signals passed through the pins between the first sub - OCP card and the second sub - OCP card include SLOT_ID1, P12V, P3V3, SMCLK, SMSDA, etc. in OCP 1C. Among them, SMCLK and SMSDA are used for the first sub - OCP card and the second sub - OCP card to communicate with the BMC through the OCP connection slot, so that the BMC can read the type information of the first sub - OCP card and the second sub - OCP card.

[0079] Based on the above scenario description, below, in combination with the accompanying drawings and application scenarios, the OCP card configuration method provided by the embodiments of this application will be elaborated in detail.

[0080] Among them, the OCP card configuration method provided in the embodiments of this application is applied to the central processing unit (CPU) of a server. The server includes a platform control hub (PCH), an Open Compute Project (OCP) connection slot, and a baseboard management controller (BMC). The CPU is respectively connected to the PCH and the BMC, the PCH is respectively connected to the OCP connection slot and the BMC, the BMC is connected to the OCP connection slot, and the OCP connection slot is used to connect a first OCP card including a first sub-OCP card and a second sub-OCP card.

[0081] Please refer to Figure 7 , Figure 7 which shows a schematic flowchart of the OCP card configuration method provided in an embodiment of this application.

[0082] As Figure 7 shown, the OCP card configuration method provided in this application may include:

[0083] S101. During the power-on process of the server, control the PCH to determine whether the OCP connection slot is connected to the first OCP card.

[0084] Among them, the first OCP card may be referred to as a multi-functional OCP card. For the specific implementation of the first OCP card, reference may be made to Figure 2 the description of the multi-functional OCP card. For the specific implementation of the first sub-OCP card and the second sub-OCP card, reference may be made to Figure 2 the description of the first sub-OCP card and the second sub-OCP card.

[0085] Combined with Figure 1 , during the power-on process of the server, the CPU in the server may control the PCH to determine whether the OCP connection slot is connected to the first OCP card, that is, whether the first OCP card is installed. Specifically, the CPU may send a determination notice to the PCH so that the PCH determines whether the OCP connection slot is connected to the first OCP card according to the determination notice.

[0086] In some embodiments, the server may be connected to a display screen. During the power-on process of the server, controlling the PCH to determine whether the OCP connection slot is connected to the first OCP card includes: during the process of the display screen of the server displaying the login interface, controlling the PCH to determine whether the OCP connection slot is connected to the first OCP card.

[0087] S102. If the OCP connection slot is connected to the first OCP card, control the BMC to obtain first information of the first OCP card from the OCP connection slot, where the first information includes the first type of the first sub-OCP card and the second type of the second sub-OCP card.

[0088] Among them, the first information may be FRU information. Since the OCP connection slot is respectively connected to the BMC and the first OCP card, the BMC may obtain the FRU information from the OCP connection slot.

[0089] The first type of the first sub - OCP card and the second type of the second sub - OCP card can be the same or different, and this application does not make specific restrictions on this.

[0090] For example, the first type is a network card and the second type is a USB expansion interface card. Another example is that the first type of the first sub - OCP card is a high - performance hardware expansion card and the second type is a memory card.

[0091] S103: Perform a first configuration according to the first information. The first configuration is used to configure the first channel group of the PCH corresponding to the first pin of the first sub - OCP card into a first mode corresponding to the first type, and configure the second channel group of the PCH corresponding to the second pin of the second sub - OCP card into a second mode corresponding to the second type.

[0092] Among them, the first sub - OCP card has a first pin, and the second sub - OCP has a second pin. The PCH includes a first channel group and a second channel group. The first channel group includes multiple channels, the second channel group includes multiple channels, the first channel group corresponds to the first pin, and the second channel group corresponds to the second pin.

[0093] For example, the first pin of the first sub - OCP card may include the pins in the 2C area, that is, Figure 5 the pins of A1 - A28 and B1 - B28 in Figure 5 The second pin of the second sub - OCP card may include the pins in the 3C area and the 4C area, that is,

[0094] For example, the first channel group and the second channel group have a total of 16 channels. The first channel group includes 8 channels of PCIe8 - PCIe15, and the second channel group includes 8 channels of PCIe0 - PCIe7.

[0095] If the first type is a high - performance hardware expansion card, the mode of the first channel group of the PCH corresponding to the high - performance hardware expansion card is the PCIe mode, and the second type is a memory card, the mode of the second channel group of the PCH corresponding to the memory card is the SATA mode. Combining the above examples, the first configuration is used to configure the 8 channels of PCIe8 - PCIe15 corresponding to the pins of A1 - A28 and B1 - B28 in the 2C area into the PCIe mode, and configure the 8 channels of PCIe0 - PCIe7 corresponding to the pins of A29 - A42 and B29 - B42 in the 3C area and A43 - A70 and B43 - B70 in the 4C area into the SATA mode.

[0096] In some embodiments, the PCH includes a high-speed I / O bus HSIO, the HSIO is connected to an OCP connector, the HSIO includes N channels, the first channel group includes M channels out of the N channels, and the second channel group includes N-M channels out of the N channels; the first configuration is for configuring the M channels of the HSIO corresponding to the first pin of the first sub-OCP card as the first mode corresponding to the first type, and for configuring the N-M channels of the HSIO corresponding to the second pin of the second sub-OCP card as the second mode corresponding to the second type.

[0097] For example, N is 16, M is 8, the HSIO includes 16 channels, the first channel group includes 8 channels from PCIe8 to PCIe15 of the HSIO, and the second channel group includes 8 channels from PCIe0 to PCIe7 of the HSIO.

[0098] The OCP card configuration method provided by this application can, when the CPU controls the PCH to determine that the OCP card connected in the OCP connector is the first OCP card, control the BMC to obtain the first type of the first sub-OCP card and the second type of the second sub-OCP card from the OCP connector, so that the CPU can, according to the first type and the second type, configure the first channel group of the PCH corresponding to the first pin of the first sub-OCP card as the first mode corresponding to the first type, and configure the second channel group of the PCH corresponding to the second pin of the second sub-OCP card as the second mode corresponding to the second type. Thus, by connecting a multifunctional first OCP card including the first sub-OCP card and the second sub-OCP card in one OCP connector, physical space can be saved, resource waste can be avoided, and the hardware cost of the OCP card can be saved. And by means of the technology of automatically identifying the types and configurations of each sub-OCP card (such as network cards, function cards, integrated function cards, etc.), the compatibility and flexibility of the server in using the OCP card can be significantly improved.

[0099] Based on the above Figure 7 As described in the illustrated embodiments, the CPU of the server includes BIOS, the PCH includes GPIO and HSIO, the GPIO is connected to the OCP connector, and the BIOS can monitor the GPIO signals on the PCH to determine whether the OCP connector is connected to the first OCP card. When the first OCP card is connected, relevant configurations can be made for the HSIO of the PCH.

[0100] Among them, the function definition of the HSIO of the PCH is as Figure 8 shown (the example is the HSIO of the C620 PCH), and it can be seen that:

[0101] SATA0, USB0 to USB7, and PCIe0 to PCIe7 share a set of multiplexed pins, which can be configured as any one of the signals of the three functions of SATA, USB, and PCIe; SATA1, USB8 to USB9, and PCIe8 to PCIe15 share a set of multiplexed pins, which can be configured as any one of the signals of the three functions of SATA, PCIe, and USB.

[0102] In addition, PCIe0 to PCIe7 in the HSIO of the PCH are connected to the second sub - OCP card, which can be configured with the three functions of SATA, USB, and PCIe, and PCIe8 to PCIe15 in the HSIO of the PCH are connected to the first sub - OCP card, which can be configured with the three functions of SATA, USB, and PCIe. For example, if the PCIe8 to PCIe15 pins in the HSIO of the PCH are configured in the PCIe mode, the first sub - OCP card of the OCP can be designed as a general OCP board, such as a PCIe X8 OCP network card; if the PCIe0 to PCIe7 pins in the HSIO of the PCH are configured in the SATA mode, the second sub - OCP card can be designed as an OCP memory card.

[0103] Next, in combination with Figure 9 , the specific implementation process of the OCP card configuration method of this application will be introduced in detail.

[0104] Please refer to Figure 9 , Figure 9 which shows a schematic flow diagram of the OCP card configuration method provided by an embodiment of this application.

[0105] As Figure 9 shown, the OCP card configuration method provided by this application may include:

[0106] S201. During the server power - on process, monitor the GPIO signal of the GPIO in the PCH.

[0107] Among them, a basic input output system (BIOS) runs on the CPU, and the BIOS in the CPU can monitor the GPIO signal of the GPIO in the PCH.

[0108] Among them, the GPIO signal can be a GPIO level signal, or a timing signal or frequency value on the GPIO. This application does not make specific limitations on this. The following description will be made by taking the GPIO signal as a GPIO level signal as an example.

[0109] As Figure 10 shown, since the power signals on the OCP connection slot are all given from the first sub - OCP card and the second sub - OCP card (only the pins of the first sub - OCP card have power supply signals), the power supply of the second sub - OCP card (such asFigure 10 As shown in P12V and P3V3, it is transmitted through the pins between the first sub - OCP card and the second sub - OCP card. Similarly, the SLOT_ID signal on the second sub - OCP card is also transmitted through the pins between the first sub - OCP card and the second sub - OCP card.

[0110] Two GPIO pins of the GPIO of the PCH ( Figure 10 GPIO0 and GPIO1 in it) respectively control the SLOT_ID0 and SLOT_ID1 pins ( Figure 5 The range of the 1C area is OA1 - OA14 and OB1 - OB14) on the 1C area of the first OCP card Figure 10 IO0 and IO1 in it), and the area where the CPU monitors the GPIO level signal on the PCH is the area on the PCH corresponding to the 1C area of the first OCP card.

[0111] On the circuit from the PCH to the OCP connection slot, a pull - up circuit is used to pull up the levels of the SLOT_ID0 and SLOT_ID1 pins. When no first OCP card or second OCP card is inserted into the OCP connection slot, the PCH will detect that the GPIO level signals on GPIO0 and GPIO1 are both high (i.e., the reading of the GPIO level signal is 0b11).

[0112] On the first sub - OCP card in the first OCP card, ground SLOT_ID0 ( Figure 10 IO0 in it), connect SLOT_ID1 to a pull - up circuit. Then, after the first sub - OCP card is inserted into the OCP connection slot, the PCH will detect that the GPIO level signal on GPIO0 is low and the GPIO level signal on GPIO1 is high (i.e., the reading of the GPIO level signal is 0b10). Also, after the second OCP card is inserted into the OCP connection slot, the PCH will detect that the GPIO level signal on GPIO0 is low and the GPIO level signal on GPIO1 is high (i.e., the reading of the GPIO level signal is 0b10).

[0113] On the second sub - OCP card in the first OCP card, ground SLOT_ID1 ( Figure 10 IO1 in it). Then, after both the first sub - OCP card and the second sub - OCP card are inserted into the OCP connection slot, the PCH will detect that the GPIO level signals on GPIO0 and GPIO1 are both low (i.e., the reading of the GPIO level signal is 0b00).

[0114] It can be seen that the GPIO level signal may have three cases, which are the third signal used to indicate that the OCP connection slot is not connected to the first OCP card or the second OCP card (this signal can be represented as 0b11), the second signal used to indicate that the OCP connection slot is connected to the second OCP card (this signal can be represented as 0b10), and the first signal used to indicate that the OCP connection slot is connected to the first OCP card (this signal can be represented as 0b00).

[0115] S202. Determine whether the GPIO signal is the first signal, where the first signal is the signal used to indicate that the OCP connection slot is connected to the first OCP card.

[0116] When it is determined that the GPIO signal is the first signal, the CPU can execute S203; when it is determined that the GPIO signal is not the first signal, the CPU can execute S207.

[0117] S203. If the GPIO signal is the first signal, determine that the OCP connection slot is connected to the first OCP card.

[0118] Based on the above description, if the GPIO signal monitored by the CPU is the first signal, it can be determined that the OCP connection slot is connected to the first OCP card. In this way, data preparation can be done for the server to perform subsequent steps related to the first OCP card.

[0119] S204. Send a read command to the BMC, where the read command is used to notify the BMC to obtain the first information of the first OCP card from the OCP connection slot.

[0120] Specifically, the CPU in the server can send a read command to the BMC so that the BMC reads the first information of the first OCP card from the OCP connection slot, and the first information includes the first type of the first sub - OCP card and the second type of the second sub - OCP card.

[0121] S205. Receive the first information of the first OCP card from the BMC, where the first information is obtained by the BMC from the OCP connection slot.

[0122] In some embodiments, when receiving the read command sent by the CPU, the BMC can read the first information of the first OCP card from the OCP connection slot and send the first information to the CPU.

[0123] In other embodiments, when receiving the read command sent by the CPU, the BMC can read the first information of the first OCP card from the OCP connection slot, perform data parsing and processing on the first information (such as processing it into a format readable by the CPU), and then send the processed first information to the CPU.

[0124] Optionally, the PCH is connected to the BMC, and the CPU of the server can also send a read command to the BMC through the PCH, and receive the first information through the BMC and the PCH.

[0125] S206. Perform a first configuration according to the first information. The first configuration is used to configure the first channel group of the PCH corresponding to the first pin of the first sub-OCP card into the first mode corresponding to the first type, and configure the second channel group of the PCH corresponding to the second pin of the second sub-OCP card into the second mode corresponding to the second type.

[0126] Among them, the implementation of S206 is similar to that of S103 in the Figure 7 illustrated embodiment, and will not be elaborated here.

[0127] S207. Determine whether the GPIO signal is a second signal. The second signal is a signal used to indicate that the OCP connection slot is connected to the second OCP card.

[0128] Among them, for the description of the second signal, reference can be made to the description of the second signal in S201.

[0129] S208. If the GPIO signal is the second signal, determine that the OCP connection slot is connected to the second OCP card.

[0130] Based on the description of S201 above, if the GPIO signal monitored by the CPU is the second signal, it can be determined that the OCP connection slot is connected to the second OCP card.

[0131] S209. Perform a second configuration according to the third type. The second configuration is used to configure the third channel group of the PCH into the third mode corresponding to the third type. The third type is the type of the second OCP card, and the third channel group includes the first channel group and the second channel group.

[0132] Among them, the third channel group includes the first channel group and the second channel group. That is to say, the second configuration is used to configure both the first channel group and the second channel group of the PCH into the third mode corresponding to the third type.

[0133] For example, the first channel group and the second channel group have a total of 16 channels. The first channel group includes 8 channels from PCIe8 to PCIe15, and the second channel group includes 8 channels from PCIe0 to PCIe7.

[0134] If the third type is a high-performance hardware expansion card, the mode of the PCH corresponding to the high-performance hardware expansion card is the PCIe mode, and the second configuration is used to configure all 16 channels from PCIe0 to PCIe15 into the PCIe mode.

[0135] In some embodiments, the PCH includes HSIO, and the HSIO is connected to the OCP connection slot. The HSIO includes N channels, and the second configuration is used to configure all N channels of the HSIO into the third mode corresponding to the third type.

[0136] For example, N is 16, the HSIO includes 16 channels, the first channel group includes 8 channels from PCIe8 to PCIe15 of the HSIO, the second channel group includes 8 channels from PCIe0 to PCIe7, and the third channel group includes 8 channels from PCIe0 to PCIe16.

[0137] In this application, the BIOS in the CPU automatically monitors the GPIO signals on the PCH. The GPIO signals are divided into three types: the third signal for indicating that the OCP connection slot is not connected to the first OCP card and the second OCP card, the second signal for indicating that the OCP connection slot is connected to the second OCP card, and the first signal for indicating that the OCP connection slot is connected to the first OCP card. When it is determined that the GPIO signal is the first signal, the CPU can determine that the OCP connection slot is connected to the first OCP card. Thus, the CPU can send a read command to the BMC so that the BMC can obtain the first information of the first OCP card from the OCP connection slot, facilitating the CPU to perform the first configuration according to the first information. When it is determined that the GPIO signal is the second signal, the CPU can determine that the OCP connection slot is connected to the second OCP card. Thus, the CPU can perform the second configuration according to the type of the second OCP card. Therefore, by the cooperation of the BIOS and the BMC, reading the GPIO signal and the first information, and automatically configuring the pin status of the PCH, compared with the method of manually intervening and configuring the OCP card through physical switches and other means, it can ensure the correct configuration of resources, simplify the configuration process of hardware resources, reduce the possibility of human configuration errors, and ensure the fast and accurate resource configuration during the system startup process. Moreover, the automatic configuration function of the OCP card ensures that there are no conflicts in hardware resources, and all resources can be reasonably allocated according to the type and requirements of each OCP card. In addition, the BMC and the PCH work together to perform intelligent adjustment when there are problems with the OCP card hardware.

[0138] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of this application.
