Title:
SSD DATA STORAGE NODE MANAGEMENT METHOD AND APPARATUS, AND COMPUTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/062981
Kind Code:
A1
Abstract:
An SSD data storage node management method and apparatus, and a computer device. The method comprises: S1, defining a mapping table, wherein the mapping table is filled with mapping data of physical continuous addresses of buffer areas; S2, marking a head pointer and a tail pointer in the mapping table, wherein the head pointer is used for representing a buffer area that is first used, and the tail pointer is used for representing a buffer area that is last used; S3, acquiring a data storage request; S4, releasing an idle buffer area according to the data storage request and the mapping table, so as to form a target buffer area; and S5, storing data in the data storage request in the target buffer area. According to the method, linked list pointer information does not need to be maintained, such that the resource occupation of a hardware memory is reduced, a released storage node can further be re-applied for use in a timely manner, and the utilization efficiency of a data storage node is improved.
