Abstract

According to the efficient data migration method under the RAID provided by the invention, the RAID0, the RAID1, the RAID5 and the RAID6 are planned respectively, a uniform scheduling scheme is used for a data migration part, the method is simple and effective for hardware and firmware, and load balance can be ensured. After data migration, verification and updating need to be carried out in RAID5 and RAID6, at the moment, an updating algorithm provided for a scheduling scheme does not need to carry out operation on all data, the simplest data updating operation method is provided for different scenes, operation can be effectively reduced, and the data migration efficiency is improved.

Description

technical field [0001] The invention relates to the field of electronic digital data processing, in particular to an efficient data migration method under RAID. Background technique [0002] With the rapid development of communication technology and network technology, digital information is growing exponentially, and data storage technology is therefore facing huge challenges. The reliability of data in the storage system and the energy consumption of the storage system are more and more concerned by people. Nowadays, in the face of such a huge data scale, the reliability of the data in the storage system is inversely proportional to the number of components contained in the storage system, that is, the more components in the storage system, the lower the reliability of the data in the storage system. According to relevant surveys, in an Internet data center composed of 600 disks, about 30 disks will be damaged every month. In a large-scale storage system, the decline in d...
