[0040] Figure 1 is one of the flow diagrams of the PCIe-based network transmission configuration method provided by the present application. As shown in Figure 1 The PCIe-based network transmission configuration method provided by the embodiment of the present application is applied to the central processor of a server to be configured, and includes the following steps: in step 101, when it is determined that the server to be configured is powered on, a first micro control unit reads all candidate IP address information from a storage chip of the server to be configured.

[0041] The first micro control unit is a micro control unit (MCU) arranged in the central processor of the server to be configured.

[0042] It should be noted that the execution subject of the PCIe-based network transmission configuration method provided by the embodiment of the present application is a PCIe-based network transmission configuration device. The PCIe-based network transmission configuration device can be arranged on the central processor of the server to be configured, or the PCIe-based network transmission configuration device is the central processor of the server to be configured.

[0043] The application scenario of the PCIe-based network transmission configuration device is that a software code about a first micro controller unit (MCU) is implanted in a central processing unit (CPU) of a server to be configured, different IP addresses previously programmed are read out by running the code, and then are sent to MCUs in PCIe devices plugged in the server to be configured, and network communication is established between the PCIe devices of the server to be configured through different IP addresses.

[0044] The first MCU refers to an MCU deployed on a bottom plate corresponding to the CPU of the server to be configured.

[0045] Specifically, in step 101, when it is determined according to the state information of each component in the server that the server to be configured has been powered on and is in a running state, the PCIe-based network transmission configuration device running on the CPU of the server to be configured controls the first micro controller unit to read candidate IP address information previously programmed from a storage chip built in the server to be configured.

[0046] The candidate IP address information refers to different IP addresses of the same network segment previously programmed in the storage chip built in the server to be configured, and the number of the candidate IP address information is determined by the configuration of the server to be configured.

[0047] In step 102, the first micro controller unit is controlled to distribute target IP address information to each second micro controller unit through a target communication link, so that each PCIe device actually plugged in the server to be configured establishes network communication between the CPU of the server to be configured and the PCIe device according to the target IP address information read from the second micro controller unit.

[0048] The second micro controller unit refers to an MCU deployed on a bottom plate corresponding to each PCIe device plugged in the server to be configured. The target communication link refers to an IIC communication link between any second micro controller unit and the first micro controller unit, and the number of the target IP address information is less than or equal to the number of the candidate IP address information.

[0049] It should be noted that the second MCU refers to an MCU deployed on a bottom plate corresponding to each peripheral plugged in the server to be configured through a PCIe link.

[0050] The target communication link refers to an IIC communication link between the first MCU as a master device and any second MCU as a slave device.

[0051] Specifically, in step 102, the PCIe-based network transmission configuration device running on the CPU of the server to be configured selects target IP address information from the candidate IP address information, the number of which matches the actual plug-in configuration of the server to be configured, and controls the first MCU to distribute the target IP address information to the second micro control units in the PCIe devices actually plugged into the server to be configured in sequence through the connected target communication link.

[0052] After any second micro control unit receives the target IP address information, it provides the received target IP address information to the PCIe device on which it runs, so that each PCIe device automatically extracts an IP address different from others, and each PCIe device performs network communication with the central processing unit of the server to be configured according to the corresponding IP address.

[0053] The number of target IP address information is determined by the actual plug-in configuration of the server to be configured. If it is a full configuration, the number of target IP address information is equal to the number of candidate IP address information. If it is a reduced configuration, the number of target IP address information is less than the number of candidate IP address information.

[0054] After the IIC communication path between the first MCU on the bottom plate of the server CPU and the second MCU on the bottom plate of the PCIe device is opened, the first MCU reads a plurality of different IP address values from the server and sends them to a plurality of second MCUs, so that different PCIe devices perform network configuration according to the IP addresses read from the respective second MCUs. When a local area network is constructed between the master and slave PCIe devices, different IP addresses are automatically set for different PCIe slave devices by software, which not only solves the problem of IP conflict, but also avoids the process of manually setting different IP addresses for each PCIe device during product production, thereby improving network configuration efficiency and product quality.

[0055] On the basis of any of the above embodiments, before determining whether the server to be configured is powered on, the method further comprises: determining the rated maximum number of PCIe devices according to the PCIe configuration requirement of the server to be configured.

[0056] Specifically, before step 101, the PCIe-based network transmission configuration device running on the CPU of the server to be configured needs to enumerate different peripheral combinations and the rated maximum number of PCIe devices contained therein, denoted as N, in combination with its own configuration and actual configuration requirement.

[0057] Burn the IP address information in the same network segment and equal to the rated maximum number of the PCIe device as the candidate IP address information in the storage chip of the server to be configured.

[0058] Specifically, the PCIe-based network transmission configuration device running on the CPU of the server to be configured pre-burns N IP address information in different network segments as candidate IP address information in the storage chip built-in the server to be configured, so that the first MCU accesses the storage chip through IIC and reads the burned candidate IP address information.

[0059] The embodiment of the present application can improve the adaptability and expansibility of the entire network system by pre-burning the IP address information matching the PCIe configuration requirement as the candidate IP address information in the storage chip of the server, so that the first MCU reads the burned candidate IP address information and decides the distribution of IP addresses.

[0060] Figure 2 is the communication link logical diagram between the first micro control unit and the electrically erasable programmable read only memory provided by the present application. Figure 2 As shown in the above any embodiment, the storage chip of the server to be configured is an electrically erasable programmable read only memory.

[0061] Specifically, the storage chip built-in the server to be configured is an electrically erasable programmable read only memory (EEPROM), and the EEPROM has a plurality of IP addresses in the same network segment, and when the machine is powered on, the first MCU obtains the control right of the PCA9641 to access the EEPROM in communication connection with the CPU through IIC and read the IP address value.

[0062] The embodiment of the present application configures the storage chip as an electrically erasable programmable read only memory, which can continue to store data when power failure, and can be erased and rewritten under the action of higher than normal voltage, improving the convenience of development.

[0063] Figure 3 is the second flowchart of the PCIe-based network transmission configuration method provided by the present application. Figure 3 As shown in the above any embodiment, the PCIe-based network transmission configuration method provided by the embodiment of the present application is applied to each PCIe device plugged in the server to be configured, comprising: step 301, receiving the target IP address information issued by the first micro control unit through the target communication link by the second micro control unit.

[0064] The first micro control unit is a micro control unit (MCU) arranged in a central processing unit of the server to be configured. The second micro control unit is an MCU arranged in each PCIe device plugged in the server to be configured. The target communication link is an IIC communication link between any second micro control unit and the first micro control unit.

[0065] It should be noted that the execution subject of the PCIe-based network transmission configuration method provided by the embodiment of the present application is a PCIe-based network transmission configuration device. The PCIe-based network transmission configuration device can be arranged on each PCIe device plugged in the server to be configured, or the PCIe-based network transmission configuration device is each PCIe device plugged in the server to be configured.

[0066] The application scenario of the PCIe-based network transmission configuration device is to implant a software code about the second micro control unit (MCU) in each PCIe device plugged in the server to be configured, read out the IP address of the first MCU issued to the second MCU by running the code, and establish the network communication between the PCIe devices of the server to be configured directly through different IP addresses.

[0067] It can be understood that the PCIe devices plugged in the server include but are not limited to NVME hard disks, SATA hard disks, and devices with independent computing capabilities (i.e., with CPU and / or graphics processing unit (GPU)).

[0068] Since the NX computing module with CPU and GPU simultaneously only uses one system image, i.e., the virtual network card IP in the system of the NX computing module is the same when it is produced and assembled, the effect obtained by the PCIe-based network transmission configuration method provided by the embodiment of the present application is the most significant when the NX computing module is applied.

[0069] Specifically, in step 301, the PCIe-based network transmission configuration device running on the PCIe device plugged in the server to be configured controls the IIC communication link between the second MCU and the first MCU to keep communication, so as to receive the target IP address information from the first MCU.

[0070] In step 302, according to the target IP address information read from the second micro control unit, the network communication between the central processing unit of the server to be configured and each PCIe device is established.

[0071] Specifically, in step 302, the PCIe-based network transmission configuration device running on the PCIe device to be configured by the server determines that the second MCU receives the target IP address information, reads the target IP address information received by the second MCU, and automatically extracts different IP addresses for each PCIe device, and each PCIe device performs network communication with the central processor of the server according to the corresponding IP address.

[0072] The embodiment of the application passes the IIC communication path between the first MCU on the bottom plate of the server CPU and the second MCU on the bottom plate of the PCIe device, controls the first MCU to read a plurality of different IP address values from the server, and sends the plurality of different IP address values to the plurality of second MCUs, so that different PCIe devices perform network configuration according to the IP addresses read from the respective second MCUs. When a local area network is constructed between the PCIe master and slave devices, different IP addresses are automatically set for different PCIe slave devices by a software mode, which not only solves the problem of IP conflict, but also avoids the process of manually setting different IP addresses for each PCIe device in the production process, improves the network configuration efficiency and product quality.

[0073] In any of the above embodiments, the network communication between the central processor of the server to be configured and each PCIe device according to the target IP address information read from the second micro control unit comprises: writing the target IP address information read from the second micro control unit into an interface configuration file for assignment update.

[0074] Specifically, in step 302, the PCIe-based network transmission configuration device running on the PCIe device to be configured by the server determines that the second MCU receives the target IP address information, reads the target IP address information received by the second MCU, and automatically extracts different IP addresses for each PCIe device, and each PCIe device performs network communication with the central processor of the server according to the corresponding IP address.

[0075] For example, set the IP address of the network card eth0, write the following content in the interface configuration file.

[0076] auto eth0

[0077] iface eth0 inet static

[0078] address 192.168.2.18

[0079] netmask 255.255.255.0

[0080] gateway 192.168.2.1

[0081] Based on the updated interface configuration file, the network communication between the central processor of the server to be configured and the current PCIe device is re-established.

[0082] Specifically, the PCIe-based network transmission configuration device running on the PCIe device plugged into the server to be configured resets the network through the IP address value recorded in the updated interface configuration file and makes the network communication between the central processor and the current PCIe device effective.

[0083] The embodiment of the application resets the network by communicating with the second MCU, reading the target IP address information received by the second MCU, and writing the value into the interface configuration file in the system. The PCIe device obtains the IP address from its own MCU and makes the entire network communication effective.

[0084] Figure 4 is the structure diagram of the server provided by the application. On the basis of any of the above embodiments, as shown in Figure 4 The server provided by the embodiment of the application includes a server mainboard 410 for executing the PCIe-based network transmission configuration method as described above, and a PCIe device 420 connected to the server mainboard 410.

[0085] Any PCIe device 420 is used to execute the PCIe-based network transmission configuration method as described above.

[0086] The first micro control unit 411 on the server mainboard 410 forms an IIC communication link with the second micro control unit 421 on any PCIe device 420.

[0087] Specifically, when the state information of each component in the server determines that it has been in the power-on running state, the first micro control unit 411 in the server mainboard 410 reads the candidate IP address information previously burned into the storage chip built-in in the server.

[0088] The server mainboard 410 selects target IP address information from the candidate IP address information, the number of which matches the actual plugging situation of the server to be configured, and controls the first MCU 411 to distribute the target IP address information to the second micro control unit 421 in each PCIe device 420 actually plugged into the server through the connected target communication link.

[0089] Any PCIe device 420 controls the IIC communication link between the second MCU and the first MCU to remain connected. After determining that the second MCU has received the target IP address information, it reads the received target IP address information from the second MCU so that each PCIe device can automatically extract a unique IP address and conduct network communication with the central processing unit of the server to be configured based on the corresponding IP address.

[0090] This invention establishes an IIC communication path between a first MCU on the server CPU's backplane and a second MCU on the PCIe device's backplane. The first MCU reads multiple different IP address values ​​from the server and sends them to multiple second MCUs, allowing different PCIe devices to perform network configuration based on the IP addresses read from their respective second MCUs. This enables the automatic assignment of different IP addresses to different PCIe slave devices via software when building a local area network between PCIe master and slave devices. This resolves IP conflict issues and avoids the need for manual IP address assignment for each PCIe device during manufacturing, improving network configuration efficiency and product quality.

[0091] Figure 5 This is a schematic diagram of the communication link logic between the first microcontroller unit and the second microcontroller unit provided by the present invention. Figure 5 As shown, based on any of the above embodiments, an IIC arbitrator and an IIC selector are provided on any of the IIC communication links.

[0092] The IIC arbitrator is used to determine whether the control entity of the IIC link is the first microcontroller unit or the baseboard management controller.

[0093] The IIC gate is used to select the IIC communication link between different PCIe devices.

[0094] Specifically, Figure 5 The leftmost element represents the IIC interface in the first MCU, and the rightmost element, NVME_BOARD, is a board that connects the PCIe device and its backplane. The NVME0 / NVME1 markings on it represent the PCIe device and its backplane. The IIC link between the first and second MCUs must contain at least an IIC arbitrator and an IIC gate, where:

[0095] The PCA9641 is an IIC arbiter. By setting its internal registers, it can be determined whether the MCU or BMC controls the subsequent IIC link.

[0096] The PCA9546 is an IIC strobe that allows users to select and access different IIC slave devices connected to it by setting its internal registers.

[0097] On the basis of the structure as shown in the figure, the communication process between the first MCU and the second MCU is as follows: first, the first MCU will obtain the control right of the PCA9641, then respectively select the PCA9546 to connect different channels, then respectively establish IIC communication with the four second MCUs through the channels, and finally send different IP addresses to different second MCUs. Figure 5

[0098] The embodiment of the application can avoid data conflict and protect data by using conflict detection mechanism and arbitration mechanism when multiple hosts simultaneously request control of the bus by setting IIC arbitrator and IIC gate on the IIC communication link.

[0099] On the basis of any of the above embodiments, the script code for executing the PCIe-based network transmission configuration method as claimed in any of the above is built into the flashing package of the PCIe device.

[0100] Specifically, the script code of the PCIe device 420 when it executes the PCIe-based network transmission configuration method is built into the flashing package of the PCIe device 420, so that the script is automatically executed at startup, the IP address is read from the second MCU, and the IP address is written into the interface configuration file to configure the static IP of the virtual network card.

[0101] The embodiment of the application builds the script code of the PCIe device for extracting the IP address from the self MCU into the flashing package, so that the relevant link communication logic is reset when the PCIe device runs the flashing package put in advance, and the underlying data of the device is not damaged, so that the operation is more convenient and fast.

[0102] On the basis of any of the above embodiments, the PCIe device is a smart network card or a computing module.

[0103] Specifically, the PCIe device 420 is a smart network card or a computing module.

[0104] Of course, the PCIe device 420 here can also be other types of PCIe devices, which are not particularly limited in the present application.

[0105] The embodiment of the application improves the expansibility of the server through various PCIe devices, and even if the PCIe device is replaced at any time, the automatic IP address allocation can be performed through the IIC communication between the MCUs, and the efficiency of network configuration is improved.
