Abstract

The invention provides an on-board SATA hard disk lighting system and method based on IPMI, The system comprises an IPMI module, a substrate management controller BMC, a hard disk backplane, wherein the hard disk backplane is provided with a CPLD, a hard disk indicator light and a SATA interface, and the SATA interface is connected with a SATA controller and a SATA hard disk; METHODS: the IPMI module is used to obtain the working status of SATA hard disk; the IPMI module requests hard disk backplane ID number and SATA hard disk ID number; a substrate management control BMC returns a hard diskbackplane ID numb and a SATA hard disk ID number to that hard disk backplane ID number; the IPMI module sends commands to record the working state of SATA hard disk and control the indicator light ofhard disk; the base board management controller BMC receives the command of the IPMI module, records the working state of the designated SATA hard disk of the designated hard disk backplane, and transmits the control command of the corresponding hard disk indicator lamp to the CPLD. The CPLD controls the indicator light of the hard disk.

Description

technical field [0001] The invention belongs to the field of hard disk lighting, and in particular relates to an IPMI-based onboard SATA hard disk lighting system and method. Background technique [0002] IPMI is the abbreviation of Intelligent Platform management Interface. The intelligent platform management interface realizes the functions of log record, alarm, sensor status, and power on and off by sending commands to BMC. [0003] With the development of big data applications, the scope of use of servers continues to expand. When a server is used for storage, the hard disk is an important part of the server storing data. It is a kind of lighting technology in the server field to visually present the working status of the hard disk for customers to observe. At present, there are two kinds of lighting conditions that we are familiar with: one is when the hard disk is connected to the SAS / RAID card, the SATA or SAS hard disk recognizes the working status of the hard disk...
