Abstract

The present disclosure provides a capacity expansion method for a storage system, the method comprising: a management server receiving a storage system capacity expansion instruction; the management server determining a preset first threshold for data block allocation; and the management server regenerating the original data Allocation, the data blocks whose access frequency exceeds the preset first threshold are scattered and written in the solid-state disk, and the difference between the total access frequency and the space occupancy ratio of the data blocks between each solid-state disk is lower than the preset second threshold. and, the management server writes data blocks whose access frequency is lower than the preset first threshold into the mechanical hard disks in a scattered manner, and the total access frequency of the data blocks between each mechanical hard disk and the space occupancy ratio are equal to each other. The difference is below a preset third threshold. The present invention effectively improves the overall I / O performance of the system.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a storage system expansion method, a readable storage medium and a computing device. Background technique [0002] With the development of information technology, digital assets have become the core assets of enterprises and institutions. During the operation process, enterprises and institutions continue to collect and generate a large amount of data. These data are of great value and require medium and long-term storage. Therefore, for There is strong demand for storage capacity. In business scenarios, these data also include some hot data, which need to be accessed frequently, which will also cause certain pressure on the I / O of the storage system. [0003] Solid-state drives are revolutionary products in the storage field in recent years, and their I / O efficiency is several times or even dozens of times that of traditional mechanical hard drives, making them w...
