Embodiment Construction

[0053] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0054] A disk array system with highly reliable configuration information of the present invention, its structure is as follows figure 1 As shown, it includes: a disk array composed of physical disks, a system disk, and a storage operating system.

[0055] The disk array composed of physical disks is based on the X86 structure, and each disk is divided into a 64MB area from the end of the disk to store configuration information and related attributes of the configuration information. This area is called a configuration information storage block.

[0056] The relevant attributes of the configuration information are stored in the header part, including: the number of updates (indicated by the symbol cnt), the data length (indicated by the symbol len) and the data check value (indicated by the symbol mark). Update times The number of ti...

Abstract

The invention relates to a high-reliable disk array system for configuration information. The disk array system comprises a disk array and a system disk, wherein the disk array is composed of physical disks, the system disk is installed in the disk array and connected with the disk array through a universal serial bus (USB) port, the system disk is a USB startup disk format and comprises a storage operating system, an application program and a mirror image of the configuration information, and the storage operating system and the application procedure are used for managing the disk array. The disk array composed of the physical disks is constructed on a basis of an X86 structure, and an area is divided from the tail end of each of the physical disks and used for storing the configuration information and association attributes of the configuration information. According to the high-reliable disk array system for the configuration information, the copied configuration information can be directly saved in the disks and the system disk, double backups are achieved, and the disk array system is reliable.

Description

technical field [0001] The invention relates to a disk array system with highly reliable configuration information, which belongs to the field of computer data storage. Background technique [0002] The disk array system is an important external device for large-capacity data storage. A certain brand of disk array system is generally equipped with a specially developed storage operating system for control and management. Based on the disk array, combined with the storage operating system that manages the array, and various applications running on the storage operating system, it constitutes the basic framework of the data storage system, which is applied to various specific data processing and storage occasion. [0003] In the current common Windows operating system, the basic configuration information of the operating system and application programs are stored in the registry, and these configuration information is an important database to ensure the normal operation of th...
