Abstract

The present application discloses a data storage method, which is applied to the technical field of coding, and includes: receiving data to be coded; determining a coding matrix for RS coding and a Galois field GF(2m) used; Each element is replaced with the corresponding matrix, and a coded sparse matrix including only 1 and 0 is obtained; the replacement satisfies: the four operations performed by elements a and b in the Galois field and the matrix H(a) and H(b) are in the Galois field. The four operations performed in Luo Huayu are equivalent; the encoding of the data to be encoded is performed by encoding the sparse matrix, and the encoded data is obtained, so that the encoding is completed by the XOR circuit and the selection circuit in the circuit; the encoded data and the to-be-encoded data are combined into a encoded data. By applying the solution of the present application, data encoding can be performed, and the hardware implementation has high speed. The present application also discloses a data storage system, device and storage medium, which have corresponding effects.

Description

technical field [0001] The present invention relates to the technical field of coding, and in particular, to a data storage method, system, device and storage medium. Background technique [0002] At present, in the face of the storage requirements of massive data, distributed storage has been widely used. The number of nodes in a distributed storage system is large, and the reliability of a single node is usually not very high, and due to software and hardware failures, human errors and other reasons, the system often has node failures. Therefore, in order to improve the data reliability of the distributed storage system and realize the reconstruction of the original file, a certain amount of data redundancy will be stored on the basis of storing the original data, so that in the case of some node failures, it is still possible to The original file is decoded and restored to ensure the normal operation of the system. [0003] EC (Erasure Code, Erasure Code) is a forward e...
