Embodiment Construction

[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0045] An all-flash storage system is a storage system that uses all flash memory, that is, SSD (Solid State Drives, solid state drive) disks. However, because the SSD disk cannot be overwritten, it is necessary to find an unwritten location inside the SSD disk to write new data. Then, how to realize efficient data management on the SSD disk is a problem that needs to be solved. An all-flash storage space management method provided by the present ap...

Abstract

The invention discloses a full-flash memory space management method, system and equipment and a computer medium, which are applied to a full-flash memory system, and the method comprises the followingsteps: dividing a full-flash memory space into a preset number of full-flash memory blocks; counting the data use information of each full-flash memory block; For each full flash memory block, the full flash memory block is managed based on the data usage information of the full flash memory block. According to the full-flash memory space management method disclosed by the invention, the full-flash memory space is divided into the preset number of full-flash memory blocks, so that the size of a managed object during each time of management is reduced; due to the fact that the data use information of each full-flash memory block is counted, the data use information of each full-flash memory block is known and clear, then the full-flash memory blocks can be quickly and accurately managed, and the data management efficiency of the SSD disk is improved. The full-flash memory space management system and device and the computer readable storage medium disclosed by the invention also solve the corresponding technical problems.

Description

technical field [0001] The present application relates to the field of storage technology, and more specifically, to an all-flash storage space management method, system, device and computer medium. Background technique [0002] An all-flash storage system is a storage system that uses all flash memory, that is, SSD (Solid State Drives, solid state drive) disks. [0003] However, because the SSD disk cannot be overwritten, it is necessary to find an unwritten location inside the SSD disk to write new data. Then, how to realize efficient data management on the SSD disk is a problem that needs to be solved. [0004] To sum up, how to improve the data management efficiency of SSD disks is an urgent problem to be solved by those skilled in the art. Contents of the invention [0005] The purpose of the present application is to provide an all-flash storage space management method, which can solve the technical problem of how to improve the data management efficiency of SSD dis...
