A Method of Obtaining Hard Disk Status Out of Band

Abstract

The invention discloses a method for acquiring the state of a hard disk out of band, including a remote host, BMC, Expander and a hard disk, wherein the remote host accesses the BMC through a LAN or Serial interface, the Expander connects to the hard disk through sas and sata, and the BMC and the Expander physically pass through I2C connection, IPMB protocol is used for data communication. When requesting data, BMC performs Write operation as Master, and Expander performs Read operation as Slave; when data is returned, Expander performs Write operation as Master, and BMC performs Read operation as Slave. Physically connect the Expander to the BMC through I2C, a commonly used communication method, to transmit the status of the hard disk, and then perform effective remote monitoring through the BMC, providing a method for remote / out-of-band monitoring of the operating status of the hard disk.

Description

technical field [0001] The invention relates to the field of monitoring the operating status of servers and storage devices, and provides a method for remotely / out-of-band monitoring the operating status of a hard disk. [0002] technical background [0003] System running status monitoring is an important technology in the server and storage fields. The industry generally uses BMC (baseboard controller) to conduct unified out-of-band monitoring and control such as CPU status, power supply, fan, motherboard temperature, etc. This monitoring method It can be carried out independently and not controlled by the operating system. The remote administrator uses the IPMI protocol to access the BMC for remote monitoring. [0004] However, there is no uniform standard for hard disk status monitoring. On the one hand, there is no effective out-of-band monitoring of hard disk status; on the other hand, there is no solution for remotely obtaining hard disk status; Users' requirements fo...

Problems solved by technology

[0004] However, there is no uniform standard for hard disk status monitoring. On the one hand, there is no effective out-of-band monitoring of hard disk status; on the other hand, there is no solution for remotely obtaining hard disk status; Users' needs for data security and reliability are further strengthened, and the necessity of hard disk status monitoring is getting more and more attention; therefore, it is imminent to form a standard for out-of-band and remote monitoring of hard disk status
