[0037] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] It should be noted that, in the description of this application, the terms "comprises," "includes," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or device. The terms "first," "second," etc., in this application are used to distinguish similar objects and are not used to describe a specific order or precedence.

[0039] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0040] See also Figure 1 , which is a schematic diagram of the connection between a server motherboard 100 and an external device 101 in some technologies. Figure 1 In the example, the server motherboard 100 includes a communication component 11 and multiple communication ports 12. The communication component 11 may include, but is not limited to, a central processing unit (CPU) and a platform controller hub (PCH). The communication ports 12 may include, but are not limited to, PCIe slots and MCIO (Multi-Channel Input / Output) ports.

[0041] The communication component 11 can be connected to each communication port 12 through the internal bus on the server motherboard 100. Each communication port 12 can be used to connect to an external device 101 of the server motherboard 100. The external device 101 may include but is not limited to a network card, a graphics card, an expansion card, a storage controller, etc. Among them, the expansion card may include but is not limited to a PCIe switch, a riser card, etc. When the external device 101 is an expansion card, the expansion card can connect to multiple external devices 101 that need to communicate with the communication component 11. For example Figure 1In the example, one end of the expansion card can be connected to the communication port 12 of the server motherboard 100, and the other end can be connected to an external device 101 such as a network card 2, a graphics card, and a storage controller. That is, the external devices 101 such as the network card 2, the graphics card, and the storage controller can communicate with the communication component 11 on the server motherboard 100 through the expansion card. The expansion card can manage the external devices 101 to which it is connected. For example, take the PCIe switch as an example. When the communication component 11 needs to communicate with the network card 2 connected to the PCIe switch, the PCIe switch can control the communication component 11 to be connected to the network card 2. When the communication component 11 needs to communicate with the storage controller connected to the PCIe switch, the PCIe switch can control the communication component 11 to be connected to the storage controller. When the number of communication ports of the server motherboard 100 is limited, the number of external devices 101 connected to the server motherboard 100 can be expanded through the expansion card.

[0042] According to the communication bit width supported by each external device 101, each external device 101 can be connected to one or more communication ports 12 of the server motherboard 100. For ease of understanding, let's take PCIe communication as an example. Assuming that one communication port 12 of the server motherboard 100 can support 8 PCIe channels, then an external device 101 that supports 16 PCIe channels (i.e., X16 bandwidth) needs to be connected to two of the communication ports 12 of the server motherboard 100, and an external device 101 that supports 32 PCIe channels (i.e., X32 bandwidth) needs to be connected to four of the communication ports 12 of the server motherboard 100, and so on. For example Figure 1 In the example, network card 1 is connected to communication ports P15 and P16 of server motherboard 100, indicating that network card 1 supports 16 PCIe lanes. Similarly, expansion card 1 is connected to communication ports P11 to P14 of server motherboard 100, indicating that expansion card 1 supports 32 PCIe lanes.

[0043] Typically, the connection relationship between the communication port 12 of the server motherboard 100 and the external device 101 is pre-planned. The communication component 11 communicates with each external device 101 based on the pre-planned connection relationship. If the physical connection between the server motherboard 100 and the external device 101 is not performed according to the pre-planned connection, a communication failure between the server motherboard 100 and the external device 101 may occur. For example, assume that in the pre-planned connection relationship, the communication ports P11-P14 of the server motherboard 100 are used to connect to the expansion card, and the communication ports P15 and P16 are used to connect to the network card 1. However, during the actual physical connection, the communication ports P11 and P13 are connected to the network card 1, and the communication ports P12, P14, P15, and P16 are connected to the expansion card. In this way, when the communication component 11 communicates with the expansion card through the communication ports P11-P14 according to the pre-planned connection relationship, a communication failure may occur.

[0044] In addition, even if the server motherboard 100 and the external device 101 are correctly physically connected according to the pre-planned connection relationship, if the cable used to connect the server motherboard 100 and the external device 101 has poor contact with the communication port 12, it may still cause communication failure between the server motherboard 100 and the external device 101.

[0045] In some current technologies, when a communication fault occurs between the server mainboard 100 and the external device 101, the incorrect connection relationship is usually manually checked and corrected. This method is time-consuming and has a low efficiency in locating the communication fault.

[0046] In view of this, the present application provides a server motherboard that can automatically check the communication port with connection errors, thereby improving the efficiency of locating communication faults and solving the problem of low efficiency of locating communication faults in some technologies. Figure 2 , which is a module diagram of the server motherboard 200 provided in some embodiments of the present application. Figure 2 In the example, the server motherboard 200 includes a communication component 21, a communication controller 23, and multiple communication ports 22. The communication component 21 is similar to the communication component 11 described above and will not be described in detail here. The communication controller 23 may include, but is not limited to, a complex programmable logic device (CPLD).

[0047] Each communication port 22 may include a first pin 221 and a second pin 222. The first pins 221 of at least two communication ports 22 are used to connect to one of the external devices 201 of the server motherboard 200, and the second pins 222 of at least two communication ports 22 are used to connect to one of the external devices 201 of the server motherboard 200. Normally, the first pin 221 and the second pin 222 of the same communication port 22 are used to connect to the same external device 201. For example, Figure 2 In the embodiment, the first pins 221 and the second pins 222 of the communication ports P21 to P24 can be used to connect to the expansion card, and the first pins 221 and the second pins 222 of the communication ports P25 and P26 can be used to connect to the network card 1.

[0048] The communication component 21 is configured to connect to the first pins 221 of each communication port 22 and communicate with the external device 201 according to the first communication protocol. The communication controller 23 is configured to connect to the second pins 222 of each communication port 22 and detect the actual connection relationship between the communication port 22 and the external device 201 according to the second communication protocol. Furthermore, based on the actual connection relationship and a pre-set planned connection relationship, the communication component 21 determines whether communication with each external device 201 is performed through the planned communication port.

[0049] Specifically, the first communication protocol refers to the protocol used by the communication component 21 and the external device 201 for normal business communications, including but not limited to the PCIe protocol. For example, when the central processing unit (CPU) serves as the communication component 21 and needs to read or write data on a storage disk, the CPU can issue read or write instructions to the storage controller (i.e., the external device 201) based on the first communication protocol. After the storage controller executes the read or write instructions issued by the CPU, it can return the execution results to the CPU based on the first communication protocol.

[0050] The second communication protocol may be the communication protocol proposed in the present application, which is mainly used to detect the actual connection relationship between the communication port 22 and the external device 201. Specifically, in this embodiment, based on the second communication protocol, the communication controller 23 may use one of the communication ports 22 of the server motherboard 200 as a chip select port, and send a communication request to each external device 201 connected to the server motherboard 200 through other communication ports other than the chip select port. Each external device 201 is configured to return a response through other communication ports other than the chip select port when receiving a communication request and determining that it is connected to the chip select port. The communication controller 23 is configured to determine the chip select port and the target communication port to which the response is received as the communication port 22 connected to the same external device 201, and obtain the actual connection relationship between the communication port 22 and the external device 201.

[0051] For ease of understanding, Figure 2 Let's take this as an example. Assume that communication controller 23 uses communication port P21 as the chip select port and sends a communication request to the connected external device 201 through communication ports P22-P2n. After the expansion card and network card 1 receive the communication request, since network card 1 is not connected to the chip select port and the expansion card is connected to the chip select port, network card 1 does not return a response. The expansion card can return a response to communication controller 23 through communication ports P22-P24. Since communication controller 23 receives the response through communication ports P22-P24, it can determine that communication port P21 and communication ports P22-P24 are connected to the same external device 201.

[0052] After determining that communication ports P21-P24 are connected to the same external device 201, communication controller 23 can continue to use communication port P25 as the chip select port and send communication requests to the connected external device 201 through communication ports P21-P24 and P26-P2n. After the expansion card and network card 1 receive the communication request, since the expansion card is not connected to the chip select port and network card 1 is connected to the chip select port, the expansion card does not return a response. Network card 1 can return a response to communication controller 23 through communication port P26. Since communication controller 23 received the response through communication port P26, it can be determined that communication ports P25 and P26 are connected to the same external device 201.

[0053] In this way, the actual connection relationship between the communication port 22 and the external device 201 can be obtained.

[0054] In other embodiments, each time parallel communication is initiated, communication ports 22 that have already been determined to be connected to the same external device 201 may be eliminated. For example, in the above example, after determining that communication ports P21-P24 are connected to the same external device 201, communication ports P21-P24 may be eliminated when parallel communication is initiated using communication port P25 as the chip select port. This means that communication requests do not need to be initiated through communication ports P21-P24. This reduces the consumption of communication resources.

[0055] In other embodiments, based on the second communication protocol, the external device 201 is configured to return a response to the communication controller 23 through all the connected communication ports 22 including the chip select port when receiving a communication request and connected to the chip select port. The communication controller 23 is configured to determine the communication port 22 that receives the response as the communication port 22 connected to the same external device 201. For example, Figure 2 In this embodiment, when communication controller 23 selects communication port P21 as the chip select port, the expansion card can return a response to communication controller 23 via all connected communication ports (i.e., communication ports P21-P24). Since communication controller 23 receives the response via communication ports P21-P24, it can determine that communication ports P21-P24 are connected to the same external device 201. In these embodiments, external device 201 returns a response to communication controller 23 via all connected communication ports 22, which can simplify the processing logic of communication controller 23 and external device 201. For example, when external device 201 receives a communication request and determines that it is connected to a chip select port, it can directly return a response based on all connected communication ports 22, without excluding the chip select port. For another example, when communication controller 23 receives a response, it can directly determine that the communication port 22 receiving the response is the communication port 22 connected to the same external device 201, without integrating the chip select port with the target communication port for receiving the response.

[0056] After the communication controller 23 determines the actual connection relationship between the communication port 22 and the external device 201, it can compare the actual connection relationship with the pre-set planned connection relationship. If the actual connection relationship is inconsistent with the planned connection relationship, the communication port with the connection error can be found and sent to the maintenance personnel. In this way, there is no need for the maintenance personnel to manually check the communication port with the connection error, which can greatly improve the efficiency of locating communication faults. For example, suppose that in the planned connection relationship, communication ports P21~P24 are used to connect to the same external device 201, and communication ports P25 and P26 are used to connect to another external device 201. However, in the actual connection relationship detected based on the second communication protocol, communication ports P21, P22, P25, and P26 are connected to the same external device 201, and communication ports P23 and P24 are connected to the same external device 201, which means that there is an error in the connection of communication ports P21~P26. In this way, maintenance personnel can directly check communication ports P21 to P26 without having to check all communication ports one by one, which can greatly improve the efficiency of communication fault locating.

[0057] Specifically, in some embodiments, the server motherboard 200 may further include a management controller 24. The management controller 24 may include, but is not limited to, a baseboard management controller (BMC) or a central processing unit (CPU). The management controller 24 may store planned connection relationships. The communication controller 23 may send actual connection relationships to the management controller 24. Based on the comparison results between the actual connection relationships and the planned connection relationships, the management controller 24 determines whether communication between the communication component 21 and each external device 201 is conducted through the planned communication ports 22. In these embodiments, having the management controller 24 perform the comparison between the actual connection relationships and the planned connection relationships reduces the computational workload of the communication controller 23. Furthermore, the management controller 24 typically includes a management interface for displaying to maintenance personnel. If the management controller 24 determines that a communication port 22 is incorrectly connected based on the comparison results, the management controller 24 may display the incorrectly connected communication port 22 on its management interface to facilitate prompting maintenance personnel.

[0058] In other embodiments, the communication controller 23 may obtain the planned connection relationship from the management controller 24 and, based on a comparison result between the actual connection relationship and the planned connection relationship, determine whether the communication component 21 and each external device 201 communicate through the planned communication port 22. In these embodiments, all connection relationship detection logic is implemented by the communication controller 23, eliminating the need to add new connection relationship detection logic to the management controller 24, thereby reducing program code changes in the management controller 24.

[0059] In summary, in the technical solutions of some embodiments of the present application, a communication controller 23 is introduced into the server motherboard 200, and the communication controller 23 is connected to the second pin 222 of the communication port 22, and the communication component 21 is connected to the first pin 221 of the communication port 22. In this way, the communication component 21 can conduct normal business communications with the external device 201 via the first pin 221 based on the first communication protocol. At the same time, the communication controller 23 can detect the actual connection relationship between the communication port 22 and the external device 201 via the second pin 222 based on the second communication protocol. When a communication failure occurs between the communication component 21 and the external device 201, the communication port 22 with the incorrect connection can be found based on the comparison result of the actual connection relationship with the planned connection relationship. In this way, there is no need to manually troubleshoot the incorrectly connected communication port 22, thereby greatly improving the efficiency of locating communication faults and solving the problem of relatively low communication fault location efficiency in some technologies.

[0060] Furthermore, in some embodiments, the number of second pins 222 can be 1. That is, each communication port 22 can include one second pin 222. When detecting the actual connection relationship between the communication port 22 and the external device 201, the communication controller 23 can communicate with the external device 201 based on the serial communication protocol. The number of first pins 221 can be set according to the provisions of the first communication protocol, and this application does not impose any restrictions on this. For example, each communication port 22 can include 16 or other numbers of pins. In these embodiments, setting the number of second pins 222 to 1 can reduce the pin consumption of each communication port 22.

[0061] The second communication protocol of this application is described in detail below.

[0062] In some embodiments, based on the second communication protocol, for any external device 201, if the external device 201 is successfully connected to the server motherboard 200, the external device 201 may set one or more communication ports 22 of the server motherboard 200 to a first electrical signal (e.g., a low level), and the duration of the first electrical signal is a first preset duration (e.g., 1 second). In response to the electrical signal of one or more communication ports 22 of the server motherboard 200 being set to the first electrical signal and lasting for the first preset duration, the communication controller 23 may determine that the external device 201 of the server motherboard 200 is successfully connected to the server motherboard 200. Specifically, if the external device 201 is successfully connected to the server motherboard 200, the external device 201 may set the connected one or more communication ports 22 to the first electrical signal (e.g., a low level), and the duration of the first electrical signal is the first preset duration (e.g., 1 second).

[0063] In the above embodiment, the external device 201 proactively sets the electrical signal of the connected communication port 22, which is equivalent to the external device 201 proactively sending a successful connection notification to the communication controller 23. This eliminates the need for the communication controller 23 to monitor whether a new external device 201 has been connected to the server motherboard 200 through timed scanning or other means. This reduces the difficulty of the communication controller 23 monitoring the external device 201 and improves the accuracy and timeliness of monitoring.

[0064] In some embodiments, based on the second communication protocol, if the server motherboard 200 successfully connects to at least one external device 201, the communication controller 23 may establish a session connection with the external device 201. Specifically, during the session connection establishment process, the communication controller 23 may exchange signals or data packets with the external device 201 to confirm the communication capabilities or communication parameters of both parties. If the session connection is successfully established, the external device 201 may set the electrical signal on the second pin 222 of at least some of the connected communication ports 22 to a third electrical signal (e.g., a high level), and the duration of the third electrical signal must reach a second preset duration (e.g., 0.5 seconds). The communication controller 23 may determine that the session connection is established successfully in response to the external device 201 setting the electrical signal on the connected communication port 22 to the third electrical signal for a duration reaching the second preset duration. In these embodiments, on the one hand, during the session connection establishment process, the communication capabilities or communication parameters between the communication controller 23 and the external device 201 may be determined, and the communication controller 23 and the external device 201 may then communicate according to the determined communication capabilities or communication parameters. This ensures communication reliability. Furthermore, after a session connection is successfully established, communication controller 23 can determine the session connection status based on the third electrical signal set by external device 201 and the duration of the third electrical signal, eliminating the need for additional monitoring methods to determine the session connection status. This avoids issues such as inaccurate monitoring of the session connection status by communication controller 23, significantly reducing the misjudgment rate of communication controller 2.

[0065] In some embodiments, based on the second communication protocol, after the session connection is successfully established, the communication controller 23 can send a data frame to the external device 201. The data frame is used to indicate the current working mode that the external device 201 needs to enter. Specifically, the working mode may include a connection relationship detection mode. The communication controller 23 can send a first data frame to each external device 201 through the communication port 22. The first data frame can be used to instruct the external device 201 to enter the connection relationship detection mode. When entering the connection relationship detection mode, the communication controller 23 can use one of the communication ports as a chip select port and initiate a communication request to each external device 201 through other communication ports other than the chip select port. Each external device 201 is used to determine whether it is connected to the chip select port. If so, it returns a response to the communication controller 23 through the other communication ports connected except the chip select port. In this way, the detection of the actual connection relationship is completed.

[0066] In some embodiments, based on the second communication protocol, the communication controller 23 can set the electrical signal of the chip select port to a second electrical signal (e.g., a low level), and set the electrical signals of other communication ports other than the chip select port to electrical signals different from the second electrical signal. In this way, each external device 201 can search among the connected communication ports 22 to see if there is a communication port 22 with the second electrical signal. If so, it determines that it is connected to the chip select port and uses the communication port 22 with the second electrical signal as the chip select port. In this way, by setting the electrical signal of the communication port 22, the communication controller 23 can synchronize the chip select port with the external device 201, greatly reducing the difficulty of synchronizing the chip select port.

[0067] In some embodiments, when the communication component 21 communicates with the external device 201, the communication component 21 may need to send communication address information to the external device 201. This communication address information can be used to characterize the correspondence between the port of the communication component 21 and the external device 201. Currently, in some technologies, this communication address information consumes seven pins of each communication port 22, meaning that each communication port 22 needs to use seven pins to send the communication address information. As technology evolves, the pins of each communication port 22 need to be utilized in a more efficient manner, and seven pins may not be available for sending the communication address information.

[0068] In view of this, the second pin 222 in each communication port 22 is used not only to detect the actual connection relationship between the communication port 22 and the external device 201, but also to send communication address information. Specifically, when the communication component 21 needs to send communication address information, the communication component 21 can send the communication address information to the communication controller 23. Based on the second communication protocol, the communication controller 23 can send a second data frame to each external device 202 through the communication port 22. The second data frame is used to instruct the external device 201 to enter the address information transmission mode. When entering the address information transmission mode, the communication controller 23 can send the communication address information obtained from the communication component 21 to the external device 201. When each communication port 22 has only one second pin 222, the communication controller 23 can send the communication address information to the external device 201 based on the serial communication protocol.

[0069] It is understandable that, compared to some technologies that use seven pins of each communication port 22 to send communication address information, this application, based on the second communication protocol, uses one pin of each communication port 22 to simultaneously detect the actual connection relationship between the communication port 22 and the external device 201 and send communication address information. This greatly reduces the pin consumption of the communication port 22.

[0070] In some embodiments, based on the second communication protocol, the communication controller 23 can use a specified number of bits to serially transmit communication address information, wherein the specified number of bits includes an identification bit and an address bit, the identification bit is used to mark the start of transmitting the communication address information, and the address bit is used to encode the communication address information. For example, the communication controller 23 can use 8 bits to transmit the communication address information. Of these 8 bits, the first bit can be used as the identification bit, and the 7 bits after the first bit can be used as address bits. The identification bit can have a specific electrical signal (such as a high level), so that the external device 201 can identify the identification bit. After identifying the identification bit, the external device 201 can use the data information in the 7 bits after the identification bit as the communication address information. In this way, reliable transmission of the communication address information is achieved.

[0071] Furthermore, when multiple communication address information is included, the 7 address bits can be divided into multiple groups, with the address bits of each group being used to transmit one communication address information. For example, the 2nd to 4th bits are used to transmit the first communication address information, and the 5th to 8th bits are used to transmit the second communication address information.
