Abstract

The invention discloses a storage space management method. The method comprises the steps of querying a target storage sub-interval of which a storage state is converted from a non-available state toan available state; judging whether adjacent storage sub-intervals exist or not; wherein the adjacent storage sub-intervals are adjacent to the physical address of the target storage sub-interval, andthe storage state of the adjacent storage sub-intervals is an available state; and if so, combining the target storage sub-interval and the adjacent storage sub-interval into an available storage sub-interval so as to write data into the available storage sub-interval. According to the invention, a continuous storage space can be provided, and the continuity of data writing is improved. The invention further discloses a storage space management system, a 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 storage space management method and system, an electronic device, and a storage medium. 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 overwriting, that is, when writing data to the same logical address, each time They are all written in the same place and overwrite 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 written in a new place ever...
