Method and system for achieving self-adaptive hard disk backboard lighting through CPLD CPLD

Abstract

The invention provides a method and a system for achieving self-adaptive hard disk backboard lighting through a CPLD. The method comprises: respectively controlling a plurality of hard disks to lightthrough reasonably designed circuits and logic language design; the CPLD sending different states through the hard disk; judging a corresponding LED state to be controlled; through the difference of data transmission between the hard disk and the master controller, the CPLD selecting corresponding lighting instructions, if a plurality of back plate modules are used on one machine at the same time,indicating LED state control of the backboard at an accurate position through different dial codes, address information and register information. Multiple types and configurations of multiplexing backboard lighting are realized, the utilization rate of a single board is improved, inventory management is reduced, income is improved, new material number application and material management are saved, original communication and data transmission are ensured, reusability is ensured, and the burden of a whole purchasing and inventory system is reduced.

Description

technical field [0001] The invention relates to the technical field of server design, in particular to a method and system for realizing self-adaptive hard disk backplane lighting by using CPLD. Background technique [0002] In the era of cloud computing, the storage of massive data requires a large amount of storage space, and a large amount of storage needs will be composed of multiple servers. The hard disk is connected to the server through the hard disk backplane to form a storage system. [0003] At present, according to different needs, the hard disk backplane will perform data transmission with the SAS card, RAID card, and PCH. At this time, the lighting link is different. Multiple backplanes are applied to the same model at the same time. To achieve lighting, it will lead to differences in the hard disks used in different application scenarios. If the part number is not differentiated, it will be impossible to distinguish, but if the part number is used to distingu...
