Problems solved by technology

Therefore, it is generally to query the number of erases and writes of all BLOCKs to determine the data block with the least number of erases and writes, but the query efficiency is extremely low, which increases the use delay of the solid state drive

Abstract

The invention discloses a data block erasing method. The method comprises the following steps: numbering each data block in a solid state disk; determining a serial number range according to the serial number of the data block which is erased last time; performing searching according to the serial number range and the erasing frequency of the data block which is erased last time to obtain a target data block; and erasing the target data block. According to the method and device, the number range is determined through the recorded number of the data block which is erased last time, and then the target data block is obtained by searching according to the number range and the erasing frequency of the data block which is erased last time, namely, the erasing range of the data block is reduced, the query of the whole disk is avoided, the query efficiency of the target data block is improved, the time delay of erasing the data block is further reduced, and the erasing efficiency is improved. The invention further discloses a data block erasing device, a server and a computer readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data block erasing method, a data block erasing device, a server, and a computer-readable storage medium. Background technique [0002] With the continuous development of data storage technology, in order to improve the speed of data processing in the storage device and reduce the processing delay. Generally, SSD (Solid State Disk, solid state drive) is used in the storage device. [0003] In related technologies, SSD uses NAND (NAND flash memory, computer flash memory device) as a storage medium. When a large amount of data needs to be written, the SSD controller receives the command and receives the corresponding data, writes the data to the NAND, and records the LBA (Logical Block Address) information of the data at the same time as the metadata The data is processed in the log module and finally saved in NAND. When the NAND is full, it is necessary to find th...
