[0021] In an embodiment of the present application, the motherboard (MB) is the main circuit board of the server, which includes core components such as CPU, memory, and provides expansion slots and other interfaces. Specifically, it may include: a programmable logic device for implementing specific logic functions, such as signal control and interface management. PCH (Platform Controller Hub) is responsible for managing the input / output functions on the motherboard, such as SATA, USB and other interfaces. BMC (Baseboard Management Controller) is responsible for monitoring, management and maintenance tasks of the server, such as remote control, hardware status monitoring, etc. The MCIO high-speed connector is used for high-speed data transmission between the motherboard and other components (such as the riser board).

[0022] In the embodiment of the present application, the expansion board provides additional PCIe slots and other functions, and two MCIO high-speed connectors are used for high-speed connection with the main board and the data processor unit network card. The first high-speed connector: connected to the main board, for data and signal transmission. The second high-speed connector: connected to the data processor unit network card, also for data and signal transmission.

[0023] In an embodiment of the present application, the data processor unit network card (data processor unit network card) has a main control chip and can independently run business processing tasks.

[0024] The switching multiplexer (PCI Express Multiplexer) switches the signal path according to the control instructions and connects the motherboard or data processor unit network card. The MCU (Microcontroller Unit) is responsible for logical judgment and generating control instructions. The EEPROM (Electrically Erasable Programmable Read-Only Memory) is used to store firmware or configuration data. The PCIE slot is used to insert PCIe devices, such as network cards, graphics cards, etc.

[0025] In the embodiment of the present application, after the server is powered on, the microcontroller unit starts working. The MCU generates control instructions according to the in-place signals of the PCIE slot, the expansion board and the data processor unit network card. The in-place signal is a signal indicating whether the corresponding device is correctly installed in place.

[0026] The switch multiplexer controls the connection mode between the motherboard and the data processor unit network card and the expansion board according to the control instructions generated by the MCU. This connection mode is determined to identify the device connected to the PCIE slot, that is, to determine which component (motherboard or data processor unit network card) will communicate with the PCIE device.

[0027] In this way, the system can automatically identify the device connected to the PCIE slot and configure the corresponding communication path based on the identification result.

[0028] In an embodiment of the present application, after the server is powered on, the microcontroller unit starts working. The microcontroller unit generates control instructions according to the in-place signals of the PCIE slot, the expansion board, and the data processor unit network card. The switching multiplexer controls the connection mode between the mainboard and the data processor unit network card and the expansion board according to the control instructions generated by the microcontroller unit. The connection mode is determined by the device connected to the PCIE slot, that is, which component will communicate with the PCIE device, and then the PCIE device is identified. The embodiment of the present application improves the flexibility and scalability of the server, allowing automated device identification and configuration under different hardware configurations, thereby optimizing the performance and maintenance efficiency of the server.

[0029] Optionally, the control unit is specifically used to: When the in-position signals of the PCIE slot, the expansion board and the data processor unit network card are all at low levels, the control unit sends a first control instruction to the switch multiplexer; The first control instruction is used to instruct the switching multiplexer to connect the second high-speed connector with the PCIE slot, so that the high-speed PCIE signal, 100M clock, frequency reduction signal, reset signal and Wake signal of the PCIE slot are transmitted to the data processor unit network card through the switching multiplexer and the second high-speed connector; When the in-place signals of the PCIE slot and the expansion board are at a low level and the in-place signal of the data processor unit network card is at a high level, the control unit sends a second control instruction to the switching multiplexer; Among them, the second control instruction is used to instruct the switching multiplexer to connect the second high-speed connector with the PCIE slot, so that the high-speed PCIE signal, 100M clock, frequency reduction signal, reset signal and Wake signal of the PCIE slot are transmitted to the mainboard through the switching multiplexer via the first high-speed connector.

[0030] In an embodiment of the present application, the micro control unit receives presence signals of the PCIE slot, the expansion board and the data processor unit network card, and generates corresponding control instructions according to these signals.

[0031] In the embodiment of the present application, a signal is used to indicate whether the PCIE slot, expansion board and data processor unit network card are correctly installed in place.

[0032] When the in-position signals of the PCIE slot, the expansion board, and the data processor unit network card are all low, the MCU controller sends a first control instruction to the switch multiplexer. The first control instruction instructs the switch multiplexer to connect the second high-speed connector to the PCIE slot, allowing the following signal transmissions: High-speed PCIE signal: data transmission; 100M clock signal: synchronization signal; frequency reduction signal: may be used to adjust the operating frequency of the device; reset signal: used to reset the device; Wake signal: wake up the device.

[0033] Through a second high-speed connector, these signals are transmitted to the data processor unit network card, enabling it to identify and communicate with the device in the PCIE slot.

[0034] In an embodiment of the present application, when the presence signals of the PCIE slot and the expansion board are at a low level, and the presence signal of the data processor unit network card is at a high level, the MCU controller sends a second control instruction.

[0035] The second control instruction instructs the switch multiplexer to connect the first high-speed connector to the PCIE slot, allowing signals to be transmitted through the switch multiplexer and the first high-speed connector. These signals are transmitted to the mainboard through the switch multiplexer and the first high-speed connector, so that the mainboard can identify and communicate with the device in the PCIE slot.

[0036] In the embodiment of the present application, the server system can automatically adjust the signal routing according to the installation status of the hardware components to ensure that the PCIE device can be recognized and used by the correct host device (mainboard or data processor unit network card). This design improves the flexibility and automation level of the system and allows more efficient hardware management and maintenance.

[0037] Optionally, the control unit is specifically used to: When the in-place signal of the PCIE slot is at a high level and the in-place signals of the expansion board and the network card of the data processor unit are at a low level, the control unit does not send a control signal; Or, when the presence signal of the expansion board is at a low level and the presence signals of the PCIE slot and the network card of the data processor unit are at a high level, the control unit does not send a control signal; Or, when the presence signal of the expansion board is at a high level, the control unit does not send a control signal.

[0038] In the embodiment of the present application, the control unit is responsible for monitoring the presence signals of the PCIE slot, expansion board and data processor unit network card, and decides whether to send a control signal to the switch multiplexer accordingly. The signal used to indicate whether the corresponding component has been correctly installed in the server, usually a low level indicates presence, and a high level indicates absence.

[0039] When the in-position signal of the PCIE slot is high, it means that no PCIE device is inserted or the device is not installed correctly. At this time, the MCU controller does not send a control signal because no device needs to be connected.

[0040] When the presence signal of the expansion board is low, it means that the expansion board has been installed correctly, but when the presence signals of the PCIE slot and the data processor unit network card are high, it means that these devices are not installed correctly or are not in place. At this time, the MCU controller does not send a control signal because no device can be connected to the expansion board.

[0041] When the presence signal of the expansion board is high, it means that the expansion board is not installed correctly or is not in place. In this case, the MCU controller also does not send a control signal because the expansion board is a key part of connecting other components.

[0042] In the embodiment of the present application, the MCU controller implements intelligent monitoring and control of the server hardware configuration, and device identification and connection are performed only when all key components are correctly installed, thereby ensuring the security and functionality of the system.

[0043] Optionally, the control unit is further configured to: When the presence signals of the expansion board and the PCIE slot are at a low level and the presence signal of the data processor unit network card is at a high level, control the switch multiplexer to connect the first high-speed connector with the PCIE slot; The mainboard identifies the PCIE device and sends a debugging control signal to the control unit through the first high-speed connector, so that the control unit latches the debugging control signal; When the server is restarted, the control unit controls the connection between the main board and the network card of the data processor unit and the expansion board according to the configuration indicated by the debugging control signal.

[0044] In an embodiment of the present application, when the presence signals of the expansion board and the PCIE slot are low, indicating that they are correctly installed in place, and the presence signal of the data processor unit network card is high, indicating that it is not in place or is not correctly installed, the MCU controller executes a specific control process.

[0045] The MCU controller sends a control instruction to the switch multiplexer, instructing it to connect the first high-speed connector with the PCIE slot, thereby allowing the mainboard to identify the PCIE device through this connection.

[0046] The motherboard identifies the device connected to the PCIE slot, which may include detecting the device type, configuring device parameters, etc. After the identification is completed, the motherboard sends debug control signals to the MCU controller through the first high-speed connector. These signals may contain specific configuration information or be used to trigger specific system behaviors.

[0047] After receiving the debug control signals, the MCU controller latches them. This means that the MCU controller can remember and maintain the status of these signals even after the system is powered off or restarted.

[0048] When the server restarts, the MCU controller controls the connection between the mainboard and the data processor unit network card and the expansion board again according to the configuration indicated by the previously latched debug control signal. By latching the debug control signal, the system configuration remains unchanged after the server restarts, ensuring the persistence of the configuration and the stability of the system.

[0049] In an optional embodiment, when the server is debugged and controlled or subjectively forced to be reconfigured, that is, when the presence signals of the expansion board and the PCIE slot are low, and the presence signal of the data processor unit network card is high, and the PCIE device identification is changed to be performed by the mainboard CPU, the CPLD in the mainboard outputs a debug control signal to the MCU controller through the high-speed connector MCIOA CONN for latching, so that when the server is restarted, the MCU controller outputs an enable signal at a high level to control the switching multiplexer to switch the channel to Y=A, so that the high-speed PCIE signal, 100M clock, frequency reduction signal, reset signal and Wake signal of the PCIE slot are connected to the high-speed connector MCIOA Conn through the switching multiplexer, the MCU controller switches PCIE_Slot_I2C to MB_I2C, and the MB mainboard is powered on to perform PCIE device identification.

[0050] In an embodiment of the present application, the MCU controller not only performs real-time control when the system is running, but also remembers specific configuration information and reconfigures hardware connections based on this information after the system is restarted, thereby achieving more flexible and reliable server management.

[0051] Figure 2 A schematic diagram of the identification method flow provided in the embodiment of the present application, such as Figure 2 As shown, including: Step 210, after the server is powered on, the micro control unit generates a control instruction according to the presence signals of the PCIE slot, the expansion board and the network card of the data processor unit; Step 220: the switch multiplexer controls the connection between the mainboard and the data processor unit network card and the expansion board according to the control instruction to determine the identification device of the PCIE device.

[0052] In the embodiment of the present application, after the server is powered on, the microcontroller unit starts working. The MCU generates control instructions according to the in-place signals of the PCIE slot, the expansion board and the data processor unit network card. The in-place signal is a signal indicating whether the corresponding device is correctly installed in place.

[0053] The switch multiplexer controls the connection mode between the motherboard and the data processor unit network card and the expansion board according to the control instructions generated by the MCU. This connection mode is determined to identify the device connected to the PCIE slot, that is, to determine which component (motherboard or data processor unit network card) will communicate with the PCIE device.

[0054] In this way, the system can automatically identify the device connected to the PCIE slot and configure the corresponding communication path based on the identification result.

[0055] In an embodiment of the present application, after the server is powered on, the microcontroller unit starts working. The microcontroller unit generates control instructions according to the in-place signals of the PCIE slot, the expansion board, and the data processor unit network card. The switching multiplexer controls the connection mode between the mainboard and the data processor unit network card and the expansion board according to the control instructions generated by the microcontroller unit. The connection mode is determined by the device connected to the PCIE slot, that is, which component will communicate with the PCIE device, and then the PCIE device is identified. The embodiment of the present application improves the flexibility and scalability of the server, allowing automated device identification and configuration under different hardware configurations, thereby optimizing the performance and maintenance efficiency of the server.

[0056] Optionally, the micro control unit generates a control instruction according to the presence signals of the PCIE slot, the expansion board and the network card of the data processor unit, including: When the in-position signals of the PCIE slot, the expansion board and the data processor unit network card are all at low levels, the control unit generates a first control instruction and sends the first control instruction to the switch multiplexer; The first control instruction is used to instruct the switching multiplexer to connect the second high-speed connector with the PCIE slot, so that the high-speed PCIE signal, 100M clock, frequency reduction signal, reset signal and Wake signal of the PCIE slot are transmitted to the data processor unit network card through the switching multiplexer and the second high-speed connector; When the in-place signals of the PCIE slot and the expansion board are at a low level and the in-place signal of the data processor unit network card is at a high level, the control unit generates a second control instruction, and the control unit sends the second control instruction to the switching multiplexer; Among them, the second control instruction is used to instruct the switching multiplexer to connect the second high-speed connector with the PCIE slot, so that the high-speed PCIE signal, 100M clock, frequency reduction signal, reset signal and Wake signal of the PCIE slot are transmitted to the mainboard through the switching multiplexer via the first high-speed connector.

[0057] Figure 3 This is a schematic diagram of the identification process of an embodiment of the present application, such as Figure 3 As shown, including: When the server's AC power is turned on, the system starts to power on. The power supply voltage is supplied to the MCU controller and the switching multiplexer, starting these components.

[0058] The MCU controller receives three key in-place signals: data processor unit network card in-place signal (data processor unit network card_PRSNT_N); PCIE slot in-place signal (PCIE_Slot_PRSNT_N); expansion board in-place signal (Riser_PRSNT_N).

[0059] The MCU controller makes a logical judgment based on the level status of these in-place signals. If all three signals are low, it means that the data processor unit network card, PCIE device and expansion board are correctly installed. The MCU controller determines that the data processor unit network card is interconnected with the PCIE device.

[0060] The MCU controller enables the switch multiplexer and switches it to channel B. Channel B is connected to the MCIOB Conn connector to ensure that the signal is transmitted to the data processor unit network card. The MCU controller switches the Slot I2C to the data processor unit network card I2C channel to ensure that the I2C communication path is set correctly. The data processor unit network card starts running and performs PCIE device recognition.

[0061] If the data processor unit network card is not in place, but the PCIE slot and expansion board are in place, the MCU controller enables the swap multiplexer and switches to the MCIOA Conn connector. The MCU controller switches the Slot I2C to the MB I2C to ensure that the I2C communication path is set correctly.

[0062] When the motherboard is powered on, the CPU starts to identify the PCIE device. If the combination of the in-position signal does not meet the above two conditions, the MCU controller does not perform any operation.

[0063] When the server is debugged and controlled or subjectively forced to be reconfigured, that is, when the expansion board is in place, the PCIE slot is in place, and the data processor unit network card is in place, the MB motherboard CPU is used to identify the PCIE device, and the motherboard CPLD outputs a debug control signal to the MCU controller through the high-speed connector MCIOA CONN for latching, so that when the server is restarted, the MCU controller outputs an enable signal at a high level to control the switching multiplexer to switch the channel to Y=A, so that the high-speed PCIE signal, 100M clock, frequency reduction signal, reset signal and Wake signal of the PCIE slot are connected to the high-speed connector MCIOA Conn through the switching multiplexer, the MCU controller switches PCIE_Slot_I2C to MB_I2C, and the motherboard is powered on to identify the PCIE device.

[0064] In the embodiments of the present application, the problem that when customers need to adapt PCIE devices for both the server and the smart network card, they can only reconfigure them by changing the boards and cables is solved, the flexibility and scalability of the server configuration are improved, the design workload and configuration complexity are reduced, the convenience of customer application is improved, and the customer's business needs can be greatly met. At the same time, the server configuration can be optimized.
