Problems solved by technology

[0002] At present, in the process of using smart devices such as servers, the host (Host) of the smart device needs to perform data communication with the BMC (baseboard management controller) of the smart device, and the current communication method is under the IPMI protocol, by using the interface of the BMC (such as KCS interface) enables the host to communicate with the BMC, but the data transmission rate of this communication method is extremely slow, and due to the limitation of the transmission protocol, large files cannot be transferred between the host and the BMC, so smart devices such as servers The functions are limited (for example, the BMC upgrade operation involving a large upgrade package cannot be performed), which is inconvenient for users to use

Abstract

The invention discloses a method and device for a host to write and read data to and from a BMC. The method includes: creating a mirror image file in a storage device of the BMC; virtualizing the mirror image file into a virtual memory; The virtual storage is mounted on the host, so that the host writes data into the virtual storage; the BMC reads data from the virtual storage. The invention enables high-speed data interaction between the host and the BMC of intelligent devices such as servers, and can transmit relatively large files between the host and the BMC, while achieving convenience, low cost, and good user experience.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method for a host to write data to a BMC, a method for a host to read data to the BMC, and a device for the host to write data to the BMC. Background technique [0002] At present, during the use of smart devices such as servers, the host (Host) of the smart device needs to communicate with the BMC (Baseboard Management Controller) of the smart device. The current communication method is under the IPMI protocol, by using the BMC interface. (such as KCS interface) enables the host to communicate with the BMC, but the data transmission rate of this communication method is extremely slow, and due to the limitation of the transmission protocol, large files cannot be transmitted between the host and the BMC, so the server and other intelligent devices Its functions are limited (for example, BMC upgrade operations involving larger upgrade packages cannot be performed), which is inconve...
