Embodiment Construction

[0052] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0053] Currently, RAID 5 allows a maximum of 1 block error on a stripe, and RAID 6 allows a maximum of 2 block errors on a stripe. It can be seen that the prior art allows at most two data blocks in one stripe to have errors, and the fault tolerance rate needs to be improved. To this end, the present application provides a RAID encoding and decoding solution, which can improve the RAID fault tolerance rate.

Abstract

The application discloses a RAID encoding and decoding method, device, equipment and readable storage medium in the field of computer technology. The present application first sets an initial position array including n mutually unequal position marker values, and then determines 3 unknown data blocks based on the initial position array when solving 3 unknown data blocks. This scheme can solve 3 unknown data blocks, so at most 3 data blocks in a stripe can be allowed to have errors, which is stronger than RAID 5 and RAID 6 in terms of data recovery capability and higher fault tolerance rate. Also, using a simple array can improve the operation efficiency. This scheme is both an encoding process and a decoding process, and RAID encoding and RAID decoding can be completed based on the same logic. Correspondingly, a RAID codec device, device, and readable storage medium provided by the present application also have the above-mentioned technical effects.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a RAID encoding and decoding method, apparatus, device, and readable storage medium. Background technique [0002] At present, a large-capacity disk group can be formed by using multiple disks, which is called Redundant Arrays of Independent Disks (RAID). Based on this, technologies such as RAID 0, RAID 1, RAID 5, and RAID 6 are derived. Currently, RAID 5 and RAID 6 are commonly used. [0003] RAID 5 allows a maximum of 1 block error on a stripe, and RAID 6 allows a maximum of 2 block errors on a stripe. It can be seen that the prior art allows at most two data blocks in one stripe to have errors, and the fault tolerance rate needs to be improved. [0004] Therefore, how to improve the RAID fault tolerance rate is a problem to be solved by those skilled in the art. SUMMARY OF THE INVENTION [0005] In view of this, the purpose of the present application is t...
