Redundance type magnetic disc array storage data reliability test method and system

Abstract

A storage data reliability testing method and system of a redundant array of independent disks (RAID) can be used in executing a storage data reliability testing program for a Redundant Array of Independent Disks (RAID) so as to test whether the storage data of the disk array has reliability; moreover, the invention is characterized in that three items of testing programs are executed for the disk array, i.e. a redundant storage data testing program, a disk abridgment testing program and a disk adding testing program; therefore, the operating reliability of a RAID Level 1 reflection storage mode can be tested completely.

Description

technical field [0001] The invention relates to a computer information technology, in particular to a method and system for testing reliability of data stored in a disk array device, which can be applied to a redundant array of independent disks (RAID). Background technique [0002] Redundant Array of Independent Disks (RAID) is a computer storage data device with two or more physical hard disks, which is usually used to connect to a network server to store a very large number of computer networks data. In addition, since the redundant disk array has multiple physical hard disks, it is usually used to provide high-reliability data fault tolerance and backup functions. [0003] For data fault tolerance and backup functions, the RAID standard specifies multiple storage data modes, and these storage data modes are expressed in different levels; for example, the primary RAID storage mode (RAID Level 0) represents the storage of data in Interleaved storage on two or more physic...
