Problems solved by technology

During the reconstruction process, user I / O requests and reconstruction requests will compete for limited disk bandwidth, and the two will affect each other, which greatly affects the reconstruction efficiency and system response. The disk array reconstruction time is too long, and the stability of the storage system lower

Abstract

The invention discloses a disk array reconstruction optimization method and device. The method comprises: acquiring all write data and hot data in a storage system, wherein the hot data is data read twice at least in the whole reconstruction period of a disk array; reconstructing the disk array so that the reconstructed disk array enters a redirected state, and migrating the write data and the hot data in the reconstruction process to an idle storage device, wherein the idle storage device is a storage agent device; and when the reconstruction of the disk array is accomplished, migrating the write data and the hot data from the idle storage device to the reconstructed disk array. The method improves the stability of the storage system.

Description

technical field [0001] The invention relates to the technical field of disk arrays, in particular to a disk array reconstruction optimization method and device. Background technique [0002] At present, with the advancement of informatization, the amount of information that needs to be stored is increasing explosively, and the growing scale of storage systems has brought huge challenges to data security and reliability, especially for applications such as finance, military affairs, and large enterprises. In the field of storage systems, once an unrecoverable catastrophic failure occurs in the storage system, the enterprise will face unbearable huge losses. Reliability has become an important factor to measure the overall performance of the storage system. [0003] The disk array uses redundancy technology to improve the reliability of the storage system, but the reliability of the disk array is still faced with serious problems during reconstruction, which is mainly reflecte...
