Problems solved by technology

The KCS interface is currently the main bridge between the BMC and BIOS. Due to a large amount of data transmission, the KCS interface and the BMC IPMI are very busy. Therefore, during the BIOS startup process, errors caused by the busy KCS or IPMI often cause the BIOS to hang.
[0003] The currently used communication interface KCS between BMC and BIOS is limited by the ipmi protocol, and there is a bottleneck in data transmission speed. The efficiency and stability are not very reliable in the process of large data transmission, resulting in data exchange between BIOS and BMC. Error, so the BIOS has to increase the retry mechanism to transmit data, thus affecting the BIOS startup time

Abstract

The invention discloses a server and a method for data exchange between a BMC and a BIOS. The method comprises the following steps that: a reserved memory space is allocated in a memory space of the BMC of the server; and the BMC and the BIOS exchange data by sharing the reserved memory space. By means of the technical scheme, efficient and reliable big data exchange between the BMC and the BIOS can be achieved.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a server and a data exchange method between a BMC and a BIOS. Background technique [0002] At present, customers have more and more demands for server customization. As the health monitoring module of the server, BMC not only monitors various health states of the server, but also displays various software and hardware asset information of the server as a remote interface. Due to the limitations of hardware design, a lot of relevant information needs to be obtained by the BMC from the BIOS, or the BIOS from the BMC. In this way, there is a large amount of data exchange between the BMC and the BIOS during the BIOS startup process. The KCS interface is currently the main bridge between BMC and BIOS. Due to a large amount of data transmission, the KCS interface and BMC IPMI are very busy. Therefore, during the BIOS startup process, errors caused by busy KCS or IPMI often cause BIOS ...
