Embodiment 1

[0033] The client includes a webpage display interface, and the webpage display interface is used to display the lighting status of the hard disk. There can be multiple hard disk slots on the backplane, and there can be multiple hard disk lights corresponding to one hard disk. The webpage display interface displays the status of the hard disk lights in partitions according to the hard disk slots. The operator can upload the lighting command to the web terminal by modifying the information on the web page display interface, and then issue it to the BMC through the web terminal. The server is also configured with a DBS and a buffer (buffer). The DBS is used to store the lighting state of the hard disk, and the buffer is used to store the full-duplex serial bus (12C) command for lighting sent by the BMC.

[0034] In the present invention, the BMC-based backplane hard disk lighting method specifically includes the following steps:

Abstract

The invention provides a backboard hard disk lighting method based on a BMC, and the method comprises the following steps: the BMC sends a full-duplex serial bus command for obtaining the state of a hard disk lamp to an expansion chip regularly, the BMC obtains the state data of the hard disk lamp, and updates the state data to a client; the client sends a lighting command to the BMC, and the BMCsends a corresponding lighting full-duplex serial bus command to the expansion chip; the expansion chip analyzes a lighting full-duplex serial bus command sent by the BMC, and outputs an SGPIO signalto the CPLD device; and the CPLD device controls the lighting state of the hard disk lamp according to the SGPIO signal. According to the backboard hard disk lighting method, an operator can conveniently and rapidly locate a faulted hard disk, the time required for eliminating the hard disk fault is shortened, and the technical requirement of the operator is reduced.

Description

technical field [0001] The invention relates to the technical field of hard disk lighting, in particular to a BMC-based backplane hard disk lighting method. [0002] technical background [0003] A large number of hard disks are used in the server system, and each hard disk requires a corresponding hard disk indicator light to indicate various states of the hard disk. [0004] An existing method for pointing hard disk lights on an expander backplane (expander backplane, hereinafter referred to as the backplane) is to send commands to the backplane through the SES protocol (SCSI Enclosure Services, a chassis management protocol) through the sg_ses tool under the system. On the expansion chip (expander) of the board. The expansion chip analyzes the data, and outputs standard SGPIO (serial General-Purpose IO ports, serial general-purpose input and output interface) data to CPLD (Complex Programmable Logic Device, complex programmable logic device). CPLD analyzes the SGPIO data...
