Abstract

The invention discloses a data processing method based on a solid-state disk array, and the method comprises the following steps: determining the write access frequency of target data when the targetdata is to be written into the solid-state disk array through a memory; determining a popularity level of the target data according to the write access frequency; for each popularity level, when the data of the popularity level form a full stripe, writing the full stripe data into the data block corresponding to the popularity level of the solid-state disk array. By applying the technical scheme provided by the invention, the problem of write amplification in the solid-state disk array can be relieved, data migration in the garbage collection process is reduced, and the performance of the solid-state disk array is improved. The invention further discloses a data processing device and equipment based on the solid-state disk array and a storage medium. The data processing device and equipment have the corresponding technical effects.

Description

technical field [0001] The present application relates to the field of computer application technology, in particular to a data processing method, device, device and storage medium based on a solid-state disk array. Background technique [0002] With the rapid development of computer technology and the reduction of the cost of solid-state disks, the application of solid-state disks in storage systems is becoming more and more extensive. Flash-based SSDs have the advantages of high performance and low energy consumption. In order to further improve storage performance and data reliability, solid-state disks are often used in arrays. [0003] After the solid-state disk is formed into an array, there are two levels of write amplification: one is at the array level, when there is data update, it needs to perform a read-verify calculation-write process, forming a write amplification; the other is inside the solid-state disk, Because the basic reading and writing unit of SSD is ...
