Embodiment 1

[0036] A system for realizing the power-on / off function of the smart network card, including a host end and a remote server end, and a BMC communication connection between the host end and the remote server end;

[0037] The host end includes a main board, and the main board is provided with a smart network card and an IO expansion chip; the smart network card is connected to the main board through a PCIE interface;

[0038] The system also includes a power supply, which is used to supply power to the host;

[0039] The BMC on the remote server side is used to obtain the status of the PCIE and judge the obtained status information. If the smart network card fails PCIE, the BMC on the remote server side controls the power on and off of the smart network card through the IO expansion chip.

[0040] The motherboard is connected to the smart network card through the PCIEx16 interface;

[0041] Smart network card includes FPGA module and CX4 module;

[0042] It should be noted th...

Embodiment 2

[0052] Such as figure 1As shown, the technical solution of the present invention also provides a method for realizing the power on and off of the smart network card, including the following steps:

[0053] Communicate and connect the BMC on the remote server side with the host side;

[0054] The PCIEx16 interface is connected to the smart network card so that the two PCIEx8s are respectively connected to the FPGA module and the CX4 module of the smart network card;

[0055] The BMC obtains the status information of the PCIE connected to the smart network card;

[0056] When a PCIE failure is detected, the BMC sends a power-off command to the IO expansion chip;

[0057] The IO chip parses the BMC command and transmits it to the power supply through the SMBUS interface.

[0058] It should be noted that the BMC controls the power on and off of different modules of the smart network card by controlling the four IOs of the IO expansion chip. The I / O chip transmits the power on a...

Abstract

The invention provides a system and a method for realizing power-on and power-off functions of an intelligent network card. The system comprises a host side and a remote server side, and BMC communication connection of the host side and the remote server side is achieved; wherein the host side comprises a main board, and an intelligent network card and an IO expansion chip are arranged on the mainboard. The intelligent network card is connected with the main board through the PCIE interface. The system further comprises a power supply, and the power supply is used for supplying power to the host end. The BMC of the remote server end is used for obtaining the state of the PCIE and judging the obtained state information, and if the intelligent network card has a PCIE fault, the BMC of the remote server end controls the intelligent network card to be powered on and powered off through the IO expansion chip. The method can be operated remotely through the BMC, machine room operation is not needed, and the labor operation and maintenance cost is saved.

Description

technical field [0001] The invention relates to the technical field of smart network cards, in particular to a system and method for realizing the power-on and power-off functions of the smart network cards. Background technique [0002] With the rapid development of the server industry, the application of artificial intelligence is becoming more and more extensive. The application scenarios and needs of customers are becoming more and more diverse. In order to meet customer needs and improve product competitiveness, rapid response and rapid research and development have become the current main development mode. [0003] Smart NICs can improve application and virtualization performance, realize many advantages of software-defined networking (SDN) and network function virtualization (NFV), remove network virtualization, load balancing and other low-level functions from the server CPU, and ensure The application provides maximum processing power. At the same time, the smart ...
