Abstract

The invention relates to a system and method for controlling the restart of a single hard disk by using a BMC. The system comprises a BMC chip and a CPLD chip, wherein the BMC chip is connected with aPCIE expansion chip; a CPLD chip is connected with a cold restart controlling chip and a hard disk interface; the PCIE expansion chip is connected with the hard disk interface to receive instructionsfrom the BMC chip and conduct different kind of controls after judging the instruction information; the CPLD chip is connected with the PCIE expansion chip, a hard disk is connected with the hard disk interface; and a power supply module is connected with the cold restart controlling chip. By the communication between the BMC chip and the PCIE expansion chip, which transmits the information to the rear panel of the hard disk to conduct controls on cold and hot restarts of the hard disk, the monitoring ability of the BMC is improved, the ability of controlling the single hard disk is improved,the insufficient support for the cold start and hot restart function of the single hard disk is compensated, the maintainability of the hard disk is improved and the data protection of the hard diskis enhanced.

Description

technical field [0001] The invention belongs to the technical field of server design, and in particular relates to a system and method for controlling restart of a single hard disk by using a BMC. Background technique [0002] The development of big data is inseparable from storage media. Based on the rapid development of big data, mainstream manufacturers in the industry currently provide NVMe hard disks as storage media. This NVMe hard disk is a high-speed storage medium based on PCIE signals, and its storage speed and response speed are much higher than ordinary SATA / SAS hard disks. [0003] In the current server design, the design of the NVMe hard disk backplane is very mature, and the related function support for NVMe is gradually perfected and matured. The existing technical solutions for NVMe hard disks are all based on Intel's architecture and implementation methods. They are NVMe hard disk management methods for CPUs, but power-on / off control (cold restart) and hot...
