Implementation method and device of cache-free solid state disk, computer equipment and storage medium

Abstract

The invention relates to an implementation method and device of a cache-free solid state disk, computer equipment and a storage medium. The method comprises the following steps of: performing electrifying and initializing, and creating a cache space for dynamically loading a mapping table in the SRAM; obtaining an HMB space application request sent by the solid state disk; writing all the modulesmarked as dirty in the mapping table in the SRAM into the particles for storage according to the request, and updating the m2p table of the previous level; judging whether the applied HMB space capacity exceeds a preset value or not; if yes, enabling the firmware to execute full mapping, and loading all mapping tables into the cache space; if not, opening up a space in the HMB space to be used formapping table caching. The acceleration of the solid state disk is realized, the DRAM cache of the current mainstream solid state disk is removed, the cost of the solid state disk is reduced, and thecost competitiveness of the product is improved.

Description

technical field [0001] The present invention relates to the technical field of implementing a cache-free solid-state disk, and more specifically refers to a method, a device, a computer device, and a storage medium for implementing a cache-free solid-state disk. Background technique [0002] With the accumulation of technology, the competition of SSD (Solid State Disk) products is becoming more and more sensitive to cost; SSD firmware inevitably needs to maintain the mapping relationship between logical addresses and physical addresses. DRAM space (Dynamic Random Access Memory, that is, dynamic random access memory), and the cost of DRAM occupies a large proportion of SSD hardware, and the high cost reduces the competitiveness of the product. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, and provide a method, device, computer equipment and storage medium for implementing a cache-free solid-state hard di...
