Metadata storage management method and device for solid state disk, equipment and storage medium

Abstract

The embodiment of the invention discloses a metadata storage management method, device and equipment of a solid state disk and a computer readable storage medium. The method is applied to a solid state disk quota metadata management module. The metadata management module is used for managing metadata of the solid state disk and SLC blocks for storing the metadata. The method comprises the steps that a freeBlock list used for storing the SLC blocks into which data are not written and a usedBlock list used for storing the SLC blocks into which data are fully written are constructed in advance, and the first SLC block used for storing metadata to be written is selected from the freeBlock list; and when it is detected that metadata to be written in is written in, the metadata to be written inis stored in the first SLC block, and management information of the first SLC block is updated, wherein the management information comprises a storage data type, erasure times, a current data write-inpage number and read-write-erasure error information. According to the technical scheme, the accuracy of metadata stored in the solid state disk can be effectively guaranteed, so that the stability of the solid state disk is improved, and the fault probability is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of metadata storage, and in particular, relate to a metadata storage management method, device, device, and computer-readable storage medium of a solid-state hard disk. Background technique [0002] With the rapid development of the Internet and cloud technology, data has shown explosive growth, and the corresponding data storage technology is also facing severe challenges. In the era of big data, the storage of massive data is becoming more and more important. While the speed of computing components such as CPU is getting higher and higher, data storage has become the bottleneck of system performance improvement. Solid State Drives (SSDs) are widely used due to their fast read and write speeds, low energy consumption, and the gradual decline in NAND prices. [0003] As the application scenarios of solid-state drives become wider and more complex, the performance and capacity requireme...

Problems solved by technology

No matter in terms of performance or stability, there are strict standards. The most important aspect is the consistency of performance, that is, during the use of solid-state drives, sudden changes in read and write performance are not allowed, which will cause applications to be unpredictable. The state of the hard disk, which brings unnecessary trouble to the operation of the application
