Raid slow disk screening method and device, equipment and medium

Abstract

The invention discloses a Raid slow disk screening method, which comprises the steps of testing a to-be-tested Raid to obtain a target test result; analyzing the target test result to obtain a targetanalysis result; wherein the target analysis result comprises IOPS, bandwidth and maximum response delay of the Raid to be tested in a test state; comparing the target analysis result with a preset standard to screen out a slow disk of the Raid to be tested; wherein the preset standard is a standard set for IOPS, bandwidth and maximum response delay of the Raid to be tested in advance. Obviously,through the method provided by the invention, the to-be-tested Raid can be analyzed and screened more comprehensively, so that the accuracy of a screening result in the process of screening the slow disks in the to-be-tested Raid can be further improved. Correspondingly, the Raid slow disk screening device, the Raid slow disk screening equipment and the medium provided by the invention also have the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of computer storage, in particular to a Raid slow disk screening method, device, equipment and medium. Background technique [0002] Since Raid (Redundant Arrays of Independent Drives, disk array) can store and read data on multiple disks at the same time, thus making Raid have larger data storage space and data throughput, so Raid has been obtained in practical applications. a very wide range of applications. However, if there is a slow disk in the Raid, it will seriously affect the overall operating performance of the Raid. In the prior art, in order to judge whether there is a slow disk in the Raid, it is usually to use IOPS (Input / Output Operations Per Second, the number of read and write operations per second) to screen the slow disk in the Raid, but this slow disk Due to the simple screening parameters of the screening method, the accuracy of the slow disk screening results in Raid cannot be guarante...

However, if there is a slow disk in Raid, it will seriously affect the overall operating performance of Raid

In the prior art, in order to judge whether there is a slow disk in the Raid, it is usually to use IOPS (Input / Output Operations Per Second, the number of read and write operations per second) to screen the slow disk in the Raid, but this slow disk Due to the simple screening parameters of the screening method, the accuracy of the slow disk screening results in Raid cannot be guaranteed.

At present, there is no effective solution to this technical problem
