NAND control method, device and apparatus based on wear state

Abstract

The invention discloses an NAND control method, device and apparatus based on a wear state and a computer readable storage medium, and the method comprises the steps: monitoring the NAND wear state of a solid state disk based on a solid state disk controller, and obtaining an NAND wear state monitoring result; when the solid state disk is in the repair stage, updating the NAND control parameters of the solid state disk by utilizing the NAND wear state monitoring result at the current moment, so that maintenance personnel do not need to detect the NAND wear condition of the solid state disk, the manual maintenance task load is reduced, and the maintenance efficiency of the solid state disk is improved; and the inheritance of the repaired solid state disk on the NAND wear state before repair can be ensured, and the NAND control parameters corresponding to the actual NAND wear condition of the solid state disk are used for controlling the NAND particles of the solid state disk, so that the quality and the service life of the repaired solid state disk are ensured.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to a wear state-based NAND control method, device, equipment and computer-readable storage medium. Background technique [0002] With the development of technologies such as the Internet, cloud computing, and the Internet of Things, solid-state drives are widely used as a new generation of storage. As the bottom end of the data center, solid-state drives carry the key task of storing data. When the solid-state hard disk fails and needs to be returned to the factory for repair, the wear of the NAND particles on the solid-state hard disk itself has a great impact on the formulation of maintenance strategies. If the wear of the NAND particles is not considered, it will directly affect the health of the solid-state hard disk after repair. . In the prior art, maintenance personnel need to test the repaired solid-state hard disk to obtain the wear condition of the NAND particle...

When the solid-state hard disk fails and needs to be returned to the factory for repair, the wear of the NAND particles on the solid-state hard disk itself has a great impact on the formulation of maintenance strategies. If the wear of the NAND particles is not considered, it will directly affect the health of the solid-state hard disk after repair.

In the prior art, maintenance personnel need to test the repaired solid-state hard disk to obtain the wear condition of NAND particles, so as to formulate maintenance strategies with reference to the wear condition of NAND particles, resulting in heavy maintenance tasks for maintenance personnel
