Abstract

Embodiments of the present invention provide a method, device and storage system for allocating stored data, which are used for allocating data to be stored to at least two disks for storage. The method includes: determining a reference value according to the storage state of each disk and the first performance-capacity ratio of each disk, the first performance-capacity ratio of each disk being the ratio of the performance index of each disk to the maximum capacity of each disk; The first performance-capacity ratio and the reference value determine the second performance-capacity ratio of each disk; determine the allocation share of each disk according to the determined second performance-capacity ratio of each disk and the maximum capacity of each disk; and, according to the determined Allocating shares, allocating the received first data to each disk, so as to write the first data to each disk, improves the overall storage performance of allocating the data to be stored to be written into the storage system including at least two disks.

Description

technical field [0001] The present invention relates to the field of data storage, in particular to a storage data distribution method, device and storage system. Background technique [0002] In a distributed storage system composed of Ethernet, in a long-running environment, due to capacity expansion, equipment replacement, etc., there are disks with different performance and capacity. The performance and capacity of each disk affect the performance and capacity of the entire system. It is worth studying to make full use of the performance and capacity of each disk to ensure the maximum performance and capacity of the distributed storage system. [0003] In the prior art, a distributed storage system usually allocates storage data according to the capacity ratio of each disk. The larger the disk capacity, the more storage data is allocated. For example, for a system with a capacity of 4 Terabytes (TB for short) and 2TB disks, 4TB disks are distributed according to the cap...
