Data processing method, device and equipment and readable storage medium

Abstract

The invention discloses a data processing method and device, equipment and a readable storage medium. According to the method, the EC algorithm is used for performing data reliability protection on the solid state disk, and the number m of the verification data blocks in the EC algorithm is configurable, so that the method can tolerate more DIE faults in the disk, is not easy to lose data, has enough flexibility, and is suitable for protecting a large-capacity storage disk. Meanwhile, according to the arrangement sequence of the n user data blocks and the m verification data blocks in the currently available data block group, the data is correspondingly placed in the disk, the randomness of the verification data in the disk can be guaranteed, that is, the verification data can be possibly stored in each DIE in the disk, and therefore the data is further protected from being lost. Correspondingly, the invention provides a data processing device and equipment and a readable storage medium, which also have the above technical effects.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a data processing method, device, equipment and readable storage medium. Background technique [0002] At present, commonly used data reliability protection methods can only tolerate up to two DIE failures in the storage disk. If there are more DIE failures, the data will not be recoverable and data will be easily lost. Common data reliability protection methods such as: XOR algorithm, RAID (Redundant Arrays of Independent Disks, disk array) 5, RAID6, etc. Among them, the XOR algorithm and RAID5 can only tolerate one DIE failure in the disk, and RAID6 can only tolerate two DIE failures in the disk. Among them, DIE is also called LUN, which is a technical term in nand flash, and DIE / LUN is the basic unit for receiving and executing flash memory commands. [0003] Currently, with the increase of disk storage capacity, the number of DIEs in the disk is increasing, ...

AI Technical Summary

Problems solved by technology

[0003]At present, with the increase of the storage capacity of the disk, the number of DIEs in the disk is increasing, and the probability of causing a faulty DIE is also increasing.

Once one or two DIE failures occur, data recovery is required, which will consume a lot of storage computing power

It can be seen that the existing data reliability protection methods are not flexible enough. When used to protect large-capacity storage disks, it is easy to cause data loss, and the data recovery process that is easy to be executed frequently will consume a lot of storage computing power.
