Device for realizing disk array and method therefor

Abstract

The invention provides a device for realizing disk array and a method therefor. The method consists of the following steps: monitoring health of the discs in the array, adjusting the strategy in accordance with shifts of preinstallation, adjusting the discs in the array in a rotating manner. When the disc in operation is detected to be in the sub-healthy condition, the device starts to adjust the disc and update the data. The method can effectively prolong the life of the discs in the array on the basis of data security, thus improving the service life of the whole array.

Description

technical field [0001] The invention relates to the field of disk arrays, in particular to a disk array realization device and method. Background technique [0002] Currently, network applications are becoming more and more popular, and more and more servers, which are network core devices, are also used. As the core equipment, the server needs to run 7*24 hours (7 days a week*24 hours, which means uninterrupted operation). For customers, their data is often very important. In order to ensure data security, most servers have introduced RAID (Redundant Array of Independent Disks, Redundant Array of Independent Disk). [0003] Traditional disk arrays, in applications, ensure data security through data redundancy on different disks. For example, RAID1 uses two disks, and the data is completely consistent to achieve complete redundancy. For another example, RAID5 uses multiple disks, and writes corresponding data or parity bits on different disks. [0004] In order to ensur...

AI Technical Summary

Problems solved by technology

[0004] In order to ensure data security, traditional disk arrays require all disks in the array to run in real time, such as figure 1 The schematic diagram of the operation of the disk array shown in the first, second, and third weeks, and the server is required to be able to run 7*24, all of which have a great impact on the disks in the array, the life of the disks, and even the entire array life expectancy, causing a lot of stress
