Embodiment Construction

[0030] Embodiments of the method and system for testing the reliability of data stored in a redundant disk array device according to the present invention are disclosed in detail below in conjunction with the attached figures.

[0031] Fig. 1 shows the application mode of the redundant disk array storage data reliability test system (as indicated by the label 40, the part included in the dashed box) of a preferred embodiment of the present invention. In this embodiment, the redundant disk array The level is 1 (RAID Level 1). As shown in the figure, the redundant disk array storage data reliability testing system 40 of the present invention is carried on a computer platform in practical applications, such as a network server 10, and the network server 10 is provided with a redundant disk array ( Redundant Array of Independent Disks, RAID) 20, is used for this redundant type hard disk array 20 and carries out a storage data reliability test program, to test whether the storage d...

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...
