Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings. These implementation examples are described in sufficient detail to enable those skilled in the art to practice the invention. Logical, implementation and other changes may be made in the implementation without departing from the spirit and scope of the invention.

[0017] figure 1 It is a schematic diagram of the hardware architecture of the disk array of the present invention.

[0018] The user equipment can communicate with the disk array through a storage area network (SAN, Storage Area Network). The disk array includes multiple hardware components, such as power supply, fan, controller, host adapter, controller management module, etc. The hardware system of the disk array includes a master device and a backup slave device, and redundant resources are used to prevent or eliminate Fault. If a fault occurs, the fault handling process can be triggered to a...

Abstract

The invention provides a high availability system of a disk array. The high availability system comprises a hardware system of the disk array and a software system operating on the hardware system of the disk array. Hardware in the hardware system comprises a main device and backup auxiliary devices. When faults happen, a fault dealing process is triggered to replace faulted hardware. The software system supports fault detection and recovery, data mirroring, cache redundancy and RAID (Redundant Array of Independent Disks) fault tolerance. According to high availability system, the hardware is backed up so that system reliability is improved. In addition, the software supports data imaging, cache redundancy and RAID fault tolerance so that stable and reliable operation of the disk array is ensured, data consistency is complete, and the high availability of the whole storage system is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a high-availability system of a disk array (RAID, Redundant Arrays of independent Disks). Background technique [0002] High Availability (HA, High Availability) usually describes a system that has been specially designed to reduce downtime while maintaining high availability of its services. [0003] In the era of rapid development of modern information, the value of data far exceeds expectations, and data security and high availability of data storage systems are particularly important. Unexpected failures of storage systems or data damage will bring huge economic losses to enterprises or countries. Therefore, it is imperative to improve the high availability of the storage system disk array. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a high availability system of a disk array, which can improve ...
