Online BIOS (basic input/output system) refreshing method for multi-node server

Abstract

The invention discloses an online BIOS (basic input / output system) refreshing method for a multi-node server. The method comprises steps as follows: a two-stage gating switch circuit comprising a first-stage gating switch and second-stage gating switches is arranged between a BMC (baseboard management controller) and CPU (central processing unit) nodes, after initialization of the BMC is completed, a driver of an SPI (serial peripheral interface) controller is uploaded, an online BIOS refreshing command on a user side is waited, when the online BIOS refreshing command is received, target CPU nodes are determined, the two-stage gating switch circuit is set for gating of BIOS Flash of the target CPU nodes, a BIOS updating file is obtained from the user side, the BIOS updating file is executed for updating, and the state of the two-stage gating switch circuit is restored. With the adoption of the method, the problem about BIOS refreshing of high-density server nodes can be effectively solved, CPUs on a main board can be updated without electrification, the single BMC can manage BIOS refreshing of the multiple CPU nodes, and the method has the advantages that remote operation is realized, the method is simple and convenient, the hardware logic complexity is low, embedded software is simple to realize, the method is convenient to use and the user experience is good.

Description

technical field [0001] The invention relates to a server node BIOS refresh method in the computer field, in particular to an online BIOS refresh method oriented to multi-node servers. Background technique [0002] In modern server design, in order to meet customers' increasingly high requirements on server performance, energy consumption, and space, motherboard design becomes increasingly complex and dense. Generally, multiple (≥2) independent computing nodes are integrated on a single motherboard, and these nodes often need to update the firmware (BasicInput Output System, BIOS) of the nodes during the R&D stage or debugging and maintenance. How to quickly and conveniently Updating the BIOS, especially in high-density servers, undoubtedly puts forward higher requirements. Traditional servers generally use refresh tools to update the firmware under the operating system. There are two problems in this update method: one is that the operating system of the CPU must be able to...

Problems solved by technology

Traditional servers generally use refresh tools to update the firmware under the operating system. There are two problems in this update method: one is that the operating system of the CPU must be able to work, and when updating, you must log in to each node for burning. For high-density node servers, this method is too time-consuming and labor-intensive; second, remote operations cannot be performed, and the refresh tool generally executes the program locally, and it is necessary to use tools such as FTP to download the burning file to the local, which is inconvenient to operate

Currently, servers equipped with Baseboard Management Controller (BMC) are only partially able to refresh the single-node BIOS.
