Intelligent network card BMC (Baseboard Management Controller) communication structure and method with high universality

Abstract

The invention relates to an intelligent network card BMC communication structure with high universality which comprises a communication unit, the communication unit comprises a first interface control module, and the first interface control module is connected with a network card BMC through a bus. The first interface control module is connected with a first FIFO cache and a second FIFO cache; the first FIFO cache is connected with an Ethernet framing module, the Ethernet framing module is connected with a second interface control module, and the second interface control module is connected with a local server or other terminals through a network port; the second interface control module is connected with an Ethernet deframing module, and the Ethernet deframing module is connected with the second FIFO cache. The network card BMC is further connected with a server BMC through an I2C bus. The invention provides an intelligent network card BMC (Baseboard Management Controller) communication method with high universality. The intelligent network card BMC communication method is used for controlling a communication unit to convert communication data of a network card BMC into an Ethernet frame form, and controlling I2C communication to be formed between the network card BMC and the server BMC. The intelligent network card has the advantages of being low in complexity, high in adaptability and easy to test and maintain.

Description

technical field [0001] The present application relates to the field of smart network cards, in particular to a BMC communication structure and method of a highly versatile smart network card. Background technique [0002] The core of the smart network card is to assist the server CPU to handle the network load and program the network interface function through the FPGA. The smart network card supports the customization of data plane and control plane functions through FPGA localization programming, and assists the CPU in handling network load; it uses multiple ports and internal switches to quickly forward data and intelligently map to the network based on network data packets, application sockets, etc. related applications. The application of the smart network card in the server replaces the CPU for related network processing, which greatly liberates the performance of the server CPU. [0003] When the smart network card is applied to the server, how to better monitor and...

Problems solved by technology

It can be said that in order to achieve full intercommunication with the motherboard, the existing smart network card needs to design many additional interfaces, which increases the design complexity of the smart network card, makes the size of the smart network card larger, and increases the design cost; the complex interface design makes the smart network card span The versatility of the platform is poor, and the additional interface requires the server BMC to be configured with a matching communication path and corresponding interface. Once the server BMC does not have a corresponding interface, the smart network card cannot be adapted

Moreover, to realize the communication between the BMC of the smart network card and the BMC of the server, the BMC of the smart network card and the BMC of the server often need to use the BMC of the same manufacturer to ensure that the BMC interconnection codes are compatible, which limits the source of hardware supply and easily increases production costs. ; The network card BMC of the existing smart network card can only be accessed point-to-point through the BMC of the server where it is located, and the testability of the network card is poor
