Hard disk state monitoring system

Abstract

The invention discloses a hard disk state indicator lamp control system. The system comprises a hard disk, a programmable logic controller and an indicator lamp; the hard disk is provided with an output interface and a hard disk controller; the output interface is connected with the programmable logic controller, and the programmable logic controller is connected with the indicator lamp; the programmable logic controller samples output signals of the hard disk controller and controls the indicator lamp to act according to the level fluctuation frequency of the signals to indicate the states of the hard disk. The programmable logic controller is connected with a host CPU, and the CPU can control the indication state of a hard disk failure indicator lamp through the programmable logic controller according to the actual hard disk detection conditions. According to the hard disk state indicator lamp control system, the running states of the hard disk are collected through the hard disk controller, Active signals with different levels are output to the programmable logic controller for the different states, and the programmable logic controller analyzes the Active signals to control the indication states of the hard disk indicator lamp and the states of the hard disk failure indicator lamp. By observing the indicator lamps of the hard disk, the health state of the hard disk can be judged.

Description

technical field [0001] The invention relates to the technical field of computer hard disks, in particular to a hard disk state monitoring system. Background technique [0002] With the rise of cloud computing and big data technology, there are more and more scenarios for building large-scale computing and storage clusters on ordinary commercial machines. With the increase of storage capacity, there are more and more cases of hard disk failure. . [0003] The real-time and intuitive display of the hard disk status can effectively reflect the working status of the hard disk, so that the staff can promptly and effectively find the faulty hard disk, improve the stability of the system and the timeliness of processing the problem hard disk, and ensure the normal operation of the system. [0004] It is known that there are roughly two methods for monitoring the hard disk. One is to periodically scan the health status of the hard disk through software. This method requires a certa...
