Technical Field

[0003] This application relates to the field of server technology, and in particular to network interface card (NIC) bandwidth configuration systems, methods, devices, storage media, and program products. Background Technology

[0004] Open Compute Project (OCP) network interface cards (NICs) are high-performance network interface devices widely used in data centers with high network performance requirements. OCP NICs support a single primary bandwidth, two primary bandwidths, or a secondary bandwidth, but the hardware environment configured for each bandwidth differs. The inventors recognized that motherboards are typically designed with hardware environments tailored to OCP NICs with a single bandwidth configuration. This fixed hardware design cannot flexibly adapt to OCP NICs with different bandwidth requirements. Furthermore, OCP NICs with different bandwidths differ in the number of PCIe signals required and the interface pin definitions. Therefore, it is difficult to achieve compatibility and adaptation for multiple OCP NICs with different bandwidths on the same motherboard. This means that in practical applications, changing the bandwidth configuration of an OCP NIC requires replacing the motherboard or performing complex hardware modifications, further increasing the cost.

[0141] Controller and NIC connector wiring: The controller controls the opening and closing of the second and first fuses via the FM_P12V_OCP_EN and FM_P3V3_OCP_EN signals, thereby controlling the power-on status of the connector's P12V_OCP_STBY and P3V3_OCP_STBY signals. The controller connects to the NIC connector via the MAIN_PWR_EN and AUX_PWR_EN signals to control the power-on of the NIC's internal power supply, and connects to the NIC connector via the NIC_PWR_GOOD signal to monitor the NIC's power-on. The controller is connected to the buffer via the FM_OCP_PERST_N signal, and outputs the FM_PERST0 / 1 / 2 / 3_N signal to the network card connector to control the network card PCIe reset; the four presence signals FM_PRSNTB0 / 1 / 2 / 3_N of the network card connector are isolated by the buffer and then connected to the controller via an AND gate through the FM_OCP_PRSNT_N signal to monitor whether the network card is present; the three bandwidth allocation pins FM_BIF0 / 1 / 2 of the network card connector are directly grounded, so that the network card is in the default bandwidth allocation configuration.

[0142] The network card hot-swap circuitry is as follows: The first and second processors are connected to the controller via the VPP bus to exchange relevant hot-swap information. The controller connects to the physical hot-swap trigger via the FM_OCP_ATTEN_HP_BTN_N signal to monitor whether the user needs to perform a notification-based hot-swap of the network card. The controller controls the state of the second indicator light via the FM_OCP_PWR_LED_N signal to inform the user of the current power-on status of the network card. The controller also controls the state of the first indicator light via the FM_OCP_ATTEN_LED_N signal to inform the user whether the current network card status is abnormal. The CPU expands general-purpose input / output (PIO) through I / O expanders and monitors the high and low levels of FM_OCP_CABLE_PRSNT_N and FM_OCP_CPU_ADDRESS_N via GPIO to achieve bandwidth allocation. During the POST phase, the BIOS reads the level information of the PIO expanders via the HOST_SMBUS bus and completes bandwidth allocation based on the level status. The bandwidth configuration method is given in Table 1. GPIO is expanded using input / output expanders. Bandwidth allocation is achieved by monitoring the high and low levels of the FM_OCP_CABLE_PRSNT_N and FM_OCP_CPU_ADDRESS_N signals via GPIO. During the POST phase, the BIOS reads the level information of the input / output expanders through the HOST_SMBUS bus and completes bandwidth allocation based on the level status. The bandwidth allocation status reference table is provided.

[0143] Table 1 shows the bandwidth distribution based on the voltage levels of the first address port and the first in-situ port.

[0144] The first x8 [0:7] of the first set of PCIe ports of the processor is connected to the first x8 of the network card connector. The first connector does not require cable connection. FM_OCP_CABLE_PRSNT_N and FM_OCP_CPU_ADDRESS_N are kept high. During the BIOS POST phase, the first processor PCIe [0:7] will be configured as x8 according to Table 1. After the controller detects that the network card is in place through the FM_OCP_PRSNT_N signal, it enables the FM_P12V_OCP_EN and FM_P3V3_OCP_EN signals, controls the P12V_OCP_STBY and P3V3_OCP_STBY to power on, and drives the AUX_PWR_EN and MAIN_PWR_EN signals to control the internal power state of the network card to enable according to the timing requirements. After the network card is enabled, it will notify the controller through the NIC_PWR_GOOD signal. The controller will release the FM_OCP_PERST_N signal according to the server timing requirements, and control the OCP network card to enter the normal working state. The motherboard design can be adapted to the x8 bandwidth network card. The second, third, and fourth connectors can be brought out via cables to support other PCIe devices.

[0145] The first connector is connected to the second connector via a cable. At this time, the front x8 [0:7] of the first processor is connected to the front x8 of the network card connector, and the rear x8 [8:15] is connected to the rear x8 of the network card connector via the MCIO connector and cable. The second address port and the second presence port of the second connector are connected to the first address port and the first presence port of the first connector, respectively. FM_OCP_CABLE_PRSNT_N and FM_OCP_CPU_ADDRESS_N are pulled low. During the POST phase, the BIOS will refer to Table 1 to configure PCIe [0:15] as x16. After the controller detects that the network card is in place, it will enable the network card by pushing relevant timing signals. The motherboard design can then be adapted to the x16 bandwidth network card. The third and fourth connectors can be led out via cables to support other PCIe devices.

[0146] The first connector and the third connector are connected by a cable. At this time, the front x8[0:7] of the first processor is connected to the front x8 of the network card connector, and the front x8[0:7] of the second processor is connected to the rear x8 of the network card connector through the MCIO connector and cable. The third address port and the third presence port of the third connector are connected to the first address port and the first presence port of the first connector, respectively. FM_OCP_CABLE_PRSNT_N is pulled low while FM_OCP_CPU_ADDRESS_N is kept high. During the POST phase, the BIOS will refer to Table 1 to configure the first processor PCIe[0:7] and the second processor PCIe[0:7] as x8 respectively. After the controller detects that the network card is in place, it will enable the network card by pushing relevant timing signals. The motherboard design can then be adapted to dual x8 bandwidth network cards. The second connector and the third connector can be led out by cables to support other PCIe devices.

[0156] In response to the first connector 400 disconnecting from the second connector 500 and connecting to the third connector 600, the network interface card configuration system is configured to adapt to the two first bandwidths.

[0157] Furthermore, the network interface card (NIC) bandwidth configuration system also includes a hot-swap trigger, which generates a hot-swap signal. The NIC bandwidth configuration method also includes:

[0158] In response to the detection that the network card is in place, the first power supply and the second power supply are powered on.

[0159] In response to receiving a hot-plug signal, the bandwidth corresponding to the network card is configured according to the first signal and the second signal.

[0160] Furthermore, after configuring the bandwidth corresponding to the network card based on the first signal and the second signal, it also includes:

[0161] Enable the network card and control the second indicator light to flash until the network card is fully enabled;

[0162] The second indicator light is kept constantly lit to indicate that the network card is functioning normally.

[0163] Furthermore, network interface card (NIC) bandwidth configuration methods also include:

[0164] In response to the network card bandwidth configuration system connecting to the network card and receiving a hot-plug signal, the system controls the network card to power down.

[0165] In response to the network card completing its power-down, the network card is removed, and the first and second power supplies are powered down.

[0166] Furthermore, controlling the power-down of the network card includes:

[0167] Power off the first and second power supply ports;

[0168] Control the second indicator light to flash until the first power supply port and the second power supply port are powered off;

[0169] Upon power-down of both the first and second power supply ports, the second indicator light is turned off to indicate network card removal. Notification-based hot-plugging is supported in single x8, dual x8, and x16 bandwidth modes. The first processor and controller transmit hot-plug information via the VPP bus, as do the second processor and controller. Since the VPP bus contains hot-plug information for all PCIe devices of the CPU, it is necessary to set the VPP address for different bandwidth modes to ensure correct transmission of hot-plug information under normal bandwidth conditions. The CPU and controller can identify the currently supported network card bandwidth status through the FM_OCP_CABLE_PRSNT_N and FM_OCP_CPU_ADDRESS_N level states. Both parties set the VPP address for transmitting hot-plug information according to Table 2.

[0170] Table 2 VPP Address Allocation Table for Different Bandwidths

[0171] To perform a hot-plug notification for a network interface card (NIC), the user needs to press the hot-plug trigger. The controller detects this by sending the FM_OCP_ATTEN_HP_BTN_N signal. Based on the currently supported bandwidth, the controller then transmits the hot-plug request for the corresponding VPP address to the CPU via the VPP bus. Upon receiving this information, the CPU recognizes the NIC requesting a hot-plug operation and performs the necessary unloading and shutdown actions. After unloading, the CPU notifies the controller to power down the NIC via the VPP bus. In a dual-x8 bandwidth configuration, the controller monitors the power-down notifications from both the first and second processors. Only after receiving power-down notifications from both CPUs will the controller perform the subsequent power-down operation. The controller will control the FM_OCP_PERST_N, MAIN_PWR_EN, and AUX_PWR_EN signals according to a timing sequence to power down the network card. During power-down, the CPU will notify the controller via the VPP bus to continuously pull the FM_OCP_PWR_LED_N signal high and low, causing the second indicator light to flash until the power-down operation is complete, at which point the second indicator light will be off. At this time, the user can remove the network card. The controller will detect the removal via the FM_OCP_PRST_N signal and will pull the FM_P12V_OCP_EN and FM_P3V3_OCP_EN signals low to power down P12V_OCP_STBY and P3V3_OCP_STBY. If any fault occurs during hot-plugging, such as network card unloading failure or timeout, the CPU will notify the controller via the VPP bus to pull the FM_OCP_ATTEN_LED_N signal low to illuminate the first indicator light, informing the user that an abnormality has occurred during the hot-plugging process.

[0172] To perform a hot-plug notification for a network interface card (NIC), the user must first insert the NIC into the NIC connector. The controller detects the NIC's presence via the FM_OCP_PRSNT_N signal and raises the FM_P12V_OCP_EN and FM_P3V3_OCP_EN signals to power on P12V_OCP_STBY and P3V3_OCP_STBY. The user then presses the hot-plug trigger to notify the controller of the NIC hot-plug request. The controller sets the corresponding VPP address based on the currently supported bandwidth and transmits the hot-plug request to the CPU via the VPP bus. The CPU performs the necessary hot-plug preparations and then notifies the controller to power on the NIC via the VPP bus. In a dual x8 bandwidth configuration, the controller monitors the power-on notifications from both the first and second processors. Only after receiving power-on notifications from both CPUs will the controller perform the subsequent power-on operation. The controller will control the NIC according to the timing requirements. The M_OCP_PERST_N, MAIN_PWR_EN, and AUX_PWR_EN signals enable the network card device. During this period, the CPU will continuously pull the FM_OCP_PWR_LED_N signal high and low through the VPP bus to make the second indicator light flash until the network card is enabled, at which point the second indicator light will remain on. If any fault occurs during hot-plugging, such as network card unplugging failure or timeout, the CPU will notify the controller through the VPP bus to pull the FM_OCP_ATTEN_LED_N signal low to light up the first indicator light, informing the user that an abnormality has occurred during the hot-plugging process.
