Data equalization method, device, and computer-readable storage medium

Abstract

The embodiment of the invention discloses a data equalization method, device and a computer-readable storage medium. The method includes counting the reading and writing times of each solid-state harddisk in the cycle time; detecting whether the reading and writing times of each solid-state disk meet the preset conditions; migrating data from a solid state drive that meets preset conditions to amechanical hard drive. Read and write times reflect the performance of SSDs, and each SSD has its corresponding performance limit. By detecting the read and write times of SSDs, we can determine whether the performance limit of SSDs has been reached or not. The preset conditions contain the basis for evaluating the performance of a solid-state drive, When the reading and writing times of a certainsolid-state disk meet the preset conditions, the data in the solid-state disk can be migrated to a mechanical hard disk to reduce the reading and writing times of the solid-state disk and realize thereasonable control of the reading and writing times of the solid-state disk, so that the solid-state disk can reach a better performance state.

Description

technical field [0001] The present invention relates to the technical field of storage systems, in particular to a data equalization method, device and computer-readable storage medium. Background technique [0002] In the storage industry, as the average data read and write volume increases, the pressure on hard disks becomes greater and greater. Hard disks include solid state drives (Solid State Drives, SSD) and mechanical hard disks (Hard Disk Drive, HDD), wherein the data read rate of SSD is faster than that of HDD. In the traditional method, in order to improve the data reading performance, data is stored in a layered manner, and the data with relatively high access heat is stored in SSD, and the data with relatively low access heat is stored in HDD accordingly. [0003] With the increase of hot data on the SSD, the number of read and write operations per second (Input / OutputOperations Per Second, IOPS) on the SSD often reaches the limit of the SSD, resulting in a decl...

Problems solved by technology

[0003] With the increase of hot data on the SSD, the number of read and write operations per second (Input / OutputOperations Per Second, IOPS) on the SSD often reaches the limit of the SSD, resulting in a decline in the storage performance of the SSD. In severe cases, it will affect the normality of the SSD data. storage
