Problems solved by technology
[0003] Since every time data is written, it is written to a new place, and some data is frequently modified during the subsequent garbage collection process, so the space for storing these data needs to be frequently garbage collected and subsequently reused for writing. At the same time, because some data has not been modified for a long time, the number of times the space used to store these data will not change for a long time. Over time, due to the unbalanced use, it will eventually lead to problems in the system. The service life of SSDs is greatly reduced due to uneven wear, resulting in waste

The invention discloses a data storage method of a storage system, and the method comprises the steps: dividing a storage pool of the storage system into a plurality of storage intervals, and recording the use frequency of each storage interval; determining available storage intervals in an available state in all the storage intervals; generating an interval chain table according to the use frequency of the available storage interval; when a disk dropping space application is received, selecting an available storage interval with the highest priority from the interval linked list as a target storage interval, so as to execute a disk dropping operation on the target storage interval according to the disk dropping space application; wherein the smaller the use frequency is, the higher the priority of the available storage interval is. The storage space distribution mode can be optimized, the storage space is abraded evenly, and the service life of the storage medium in the storage systemis prolonged. The invention also discloses a data storage system of the storage system, a computer readable storage medium and electronic equipment, which have the above beneficial effects.
Description
technical field [0001] The present application relates to the technical field of data storage, and in particular to a data storage method and system of a storage system, a computer-readable storage medium, and an electronic device. Background technique [0002] All-flash storage is an important direction of storage development. With the gradual decline of SSD prices, all-flash storage products will further seize the market share of traditional storage in the future and become the main product in the storage field. Compared with traditional storage, all-flash storage has an absolute advantage in performance, and the main difference in data organization is that the data storage method of traditional storage is an overwrite method, that is, when writing data to the same logical address, each time It is written in the same place and overwrites the old data, while the all-flash storage adopts the append writing method, that is, when writing data to the same logical address, it is...
