Description

Technical Field

[0001] The present application relates to the field of server technology, and in particular to a network card bandwidth configuration system, method, device, storage medium and program product. Background Art

[0002] The Open Compute Project (OCP) network card is a high-performance network interface device that is widely used in data centers with high network performance requirements. The OCP network card supports a single first bandwidth or two first bandwidths or second bandwidths, but the hardware environment configured for the corresponding bandwidth is different. Usually, when designing a motherboard, the hardware environment is only designed for the OCP network card with a single bandwidth configuration. The fixed hardware design cannot flexibly adapt to the OCP network cards with different bandwidth requirements; and the OCP network cards with different bandwidths also have differences in the required number of PCIe signals, interface pin definitions, etc. Therefore, it is difficult to achieve compatibility and adaptation of OCP network cards with multiple different bandwidths on the same motherboard. This leads to the fact that in actual applications, if the bandwidth configuration of the OCP network card needs to be changed, the motherboard must be replaced or complex hardware modifications must be performed, which will further increase the modification cost.

[0155] In response to the first connector 400 being disconnected from the second connector 500 and connected to the third connector 600 , the network card configuration system is configured to adapt the two first bandwidths.

[0156] Furthermore, the network card bandwidth configuration system further includes a hot plug trigger, which triggers the hot plug trigger to generate a hot plug signal, and the method further includes:

[0157] In response to detecting that the network card is in place, controlling the first power supply and the second power supply to power on;

[0158] In response to receiving the hot plug signal, the bandwidth corresponding to the network card is configured according to the first signal and the second signal.

[0159] Further, after configuring the bandwidth corresponding to the network card according to the first signal and the second signal, the method further includes:

[0160] Enable the network card and control the second indicator light to flash until the network card is enabled;

[0161] Control the second indicator light to be always on to indicate that the network card is functioning normally.

[0162] Furthermore, the method further comprises:

[0163] In response to the network card bandwidth configuration system connecting to the network card and obtaining a hot plug signal, the network card is controlled to be powered off;

[0164] In response to the network card being powered off, the network card is removed, and the first power supply and the second power supply are controlled to be powered off.

[0165] Furthermore, controlling the power-off of the network card includes:

[0166] Controlling the first power supply port and the second power supply port to power off;

[0167] Control the second indicator light to flash until the first power supply port and the second power supply port are powered off;

[0168] In response to the first power supply port and the second power supply port being powered off, the second indicator light is turned off to indicate that the network card is removed.

[0169] Notification hot-plugging is supported in single x8, dual x8 and x16 bandwidth states. The first processor and the controller transmit hot-plugging information through the VPP bus, and the second processor and the controller transmit hot-plugging information through the VPP bus. Since the VPP bus contains hot-plugging related information of all PCIe devices of the CPU, it is necessary to set the VPP address under different bandwidth states to ensure the correct transmission of hot-plugging information under normal bandwidth state; the CPU and the controller can identify the currently supported network card bandwidth state through the FM_OCP_CABLE_PRSNT_N and FM_OCP_CPU_ADDRESS_N level states, and the two parties set the VPP address for transmitting hot-plugging information through Table 2.

[0170] Table 2 VPP address allocation table for different bandwidths

[0171]

[0172] If the user wants to perform a notification-based hot-plug of the network card device, the user needs to press the hot-plug trigger. After the controller detects that the hot-plug trigger is pressed through the FM_OCP_ATTEN_HP_BTN_N signal, it transmits the hot-plug request of the corresponding VPP address to the CPU through the VPP bus according to the currently supported bandwidth status. After the CPU receives the hot-plug information of the corresponding address, it knows that the corresponding network card device has applied for a hot-plug operation, and will perform relevant unloading and shutdown actions for the device. After the unloading is completed, the controller is notified through the VPP bus to power off the network card. Under the dual X8 bandwidth configuration, the controller will monitor the power-off notifications of the first processor and the second processor respectively. Only after the controller receives the power-off notifications of the two CPUs will it perform subsequent power-off operations. The controller will control the FM_OCP_PERST_N\MAIN_PWR_EN\AUX_PWR_EN signals in sequence to control the internal power-off of the network card. During the power-off period, the CPU will notify the controller through the VPP bus to continuously pull up and down the FM_OCP_PWR_LED_N signal to make the second indicator light flash until the power-off operation is completed and the second indicator light is always off. At this time, the user can unplug the network card. The controller will pull down the FM_P12V_OCP_EN\FM_P3V3_OCP_EN signals to control the power-off of P12V_OCP_STBY and P3V3_OCP_STBY when it detects the unplugging through the FM_OCP_PRSNT_N signal. If any failure occurs in the hot-swap, such as the failure or timeout of the network card uninstallation, the CPU will notify the controller through the VPP bus to pull down the FM_OCP_ATTEN_LED_N signal to light up the first indicator light to inform the user that the hot-swap process is abnormal.

[0173] If the user wants to perform a notification hot-plug of the network card device, the user needs to insert the network card into the network card connector first. At this time, the controller detects that the network card is in place through the FM_OCP_PRSNT_N signal, and will pull up the FM_P12V_OCP_EN\FM_P3V3_OCP_EN signal to control P12V_OCP_STBY and P3V3_OCP_STBY to power on. Then, the user presses the hot-plug trigger to inform the controller to hot-plug the network card device. The controller will set the corresponding VPP address according to the currently supported bandwidth status, and pass the hot-plug request to the CPU through the VPP bus through the corresponding VPP address. The CPU will perform the corresponding hot-plug preparation. After the preparation is completed, it will notify the controller to power on the network card through the VPP bus. Under the dual X8 bandwidth configuration, the controller will monitor the power-on notifications of the first processor and the second processor respectively. Only after the controller receives the power-on notifications of the two CPUs will it perform subsequent power-on operations. The controller will control F according to the timing requirements. M_OCP_PERST_N\MAIN_PWR_EN\AUX_PWR_EN signals are used to enable the network card device. During this period, the CPU will notify the controller through the VPP bus to continuously pull up and down the FM_OCP_PWR_LED_N signal to make the second indicator light flash until the network card is enabled and the second indicator light is always on; if any failure occurs in the hot insertion, such as network card uninstallation failure or timeout, the CPU will notify the controller through the VPP bus to pull down the FM_OCP_ATTEN_LED_N signal to light up the first indicator light to inform the user that the hot insertion process is abnormal.
