Abstract

The embodiment of the invention provides a storage data allocation method and device and a storage system, which are used for allocating data to be stored to at least two magnetic disks for storage. The method comprises the following steps of determining a reference value according to a storage state of each magnetic disk and first performance capacity ratio of each magnetic disk, wherein the first performance capacity ratio of each magnetic disk is ratio between the performance index of each magnetic disk and the maximum capacity of each magnetic disk; determining second performance capacity ratio of each magnetic disk according to the first performance capacity ratio of each magnetic disk and the reference value; determining allocation proportion of each magnetic disk according to the determined second performance capacity ratio of each magnetic disk and the maximum capacity of each magnetic disk; and allocating received first data to each magnetic disk according to the determined allocation proportion of each magnetic disk, so that the first data is written to each magnetic disk. By the method, the comprehensive storage performance of the storage system for allocating the data to be stored and writing the data to be stored in the storage system comprising at least two magnetic discs is improved.

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 expansion, equipment replacement and other reasons, 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 (Terabyte, TB for short) and 2TB disks, 4TB disks allocate more storage data acc...
