Abstract

The invention relates to an SSD storage data error processing method and device, equipment and a storage medium, and the method comprises the steps: obtaining error information of SSD NAND flash to complete error collection; performing data management and scheduling on the collected errors to obtain a management scheduling command; and processing the SSD storage data according to the management scheduling command. According to the method, the business layer and user layer characteristics of the data can be associated, the data importance and the system influence can be better reflected, and risk control and preprocessing can be carried out on the associated data as soon as possible, so that the loss or damage to core data can be better avoided, the scheduling with the main process of the storage equipment is well coordinated, and the scheduling efficiency is improved. And error data processing management is completed orderly.

Description

Technical field [0001] The present invention relates to the technical field of SSD storage data error handling, in particular refers to the SSD storage data error processing methods, devices, devices and storage media. Background [0002] With the application and development of SSDs in large-scale data storage systems, low latency, high performance, low write amplification, and efficient physical storage utilization have become the main technical goals of next-generation data center architecture. Open Channel (OC Open Channel) SSDs and the consequent evolution of Zone Namespace (ZNS partition namespace) SSDs are constantly being practiced and productized by enterprise SSD vendors, and the corresponding NVMe standards are gradually improved and promoted. [0003] The existing error handling of SSD storage data is often only a simple protection of data physical damage, and it is impossible to achieve risk control and pre-processing. Contents of the Invention [0004] Object of th...
