Storage array configuration preservation and arbitration method

Abstract

The invention relates to a storage array configuration preservation and arbitration method and belongs to the technical field of computer storage. The preservation method comprises the following steps: firstly dividing a configuration area and a configuration metadata area from a single disc; then obtaining system configuration data, compressing and packing the system configuration data and calculating configuration metadata from the compressed and packed system configuration data; successively, writing the configuration metadata into configuration metadata areas of all discs in a storage array; finally, writing the configuration data into configuration areas of all of the discs in the storage array. The arbitration method comprises the following steps: firstly reading the configuration metadata of all of the discs; then selecting candidate export discs according to system serial numbers and certain rules; successively, ruling out the export disc from the candidate export discs according to MD5 and a sequence; then exporting the configuration data from the export disc, decompressing, and preserving for later use of a system. Compared with a traditional configuration management method, the storage array configuration preservation and arbitration method has the benefits that storage configuration can be furthest restored; a storage system without configuration management is subjected to forward compatibility, so that system upgrade is facilitated.

Description

technical field [0001] The invention relates to a method for managing configuration information of a storage array, in particular to a storage and arbitration method for configuration information of a storage array, and belongs to the technical field of computer storage. Background technique [0002] With the emergence of broadband, mobile Internet, Internet of Things, social networks, and cloud computing, the era of big data is coming quietly. The US Internet Data Center pointed out that the data on the Internet will increase by 50% every year, and it will double every two years. At present, more than 90% of the data in the world have only been generated in recent years. [0003] With the development of big data, large-scale storage arrays are increasingly used to store and manage enterprises and data due to their high-capacity, high-performance, and high-reliability characteristics of organizing multiple single disks. Huge data in centers and computing centers. Usually, ...
