Storage hard disk power supply protection system and protection method

Abstract

The invention relates to the technical field of hard disks, and provides a storage hard disk power supply protection system, which comprises a power supply module, a management module and a pluralityof controllable overcurrent protection devices; the power supply module is used for supplying power to the hard disk interface through the controllable overcurrent protection device; the controllableover-current protection device is used for cutting off the path between the hard disk interface and the power supply module when the hard disk fails, and when the hard disk fault is eliminated, the line between the hard disk interface and the power supply module is controlled; the management module is configured to establish a communication connection with the controllable overcurrent protection device and the hard disk interface, respectively obtain the working state information of the controllable overcurrent protection device and the hard disk interface, and control the controllable overcurrent to protect the line that can be turned on and off between the hard disk interface and power module and display the operating state of hard disk, thereby providing overcurrent protection for the hard disk power supply, online replacement of the failed hard disk, and real-time monitoring and management of the entire power supply circuit.

Description

technical field [0001] The invention belongs to the technical field of hard disks, and in particular relates to a storage hard disk power supply protection system and protection method. Background technique [0002] The advent of the era of big data has made people aware of the important role of data, and as the core component of storing data in the server, the storage hard disk has become very important for its security and reliability. [0003] At present, the implementation manners of the hard disk power supply circuit in the storage module of the server are mainly divided into the following two schemes. Solution 1 is mainly composed of two parts: power supply and storage hard disk module, as follows figure 1 shown. The power supply part mainly plays the role of voltage regulation and overcurrent protection. The power supply outputs 12V and 5V voltage to supply power for the hard disk. By setting OCP parameters, the power supply can be cut off in time when the hard disk...

AI Technical Summary

Problems solved by technology

However, this implementation method also has problems. When it is necessary to replace a hard disk that has a short-circuit fault, it is first necessary to migrate the local service to another server, and then cut off the power supply of the server to replace the blown fuse on the storage backplane. The ease of use is not conducive to later maintenance
