Abstract

The invention discloses a data integrity verification method, which is applied to a storage server, and comprises the following steps: receiving N data copies transmitted by host equipment, and storing the data copies in a nonvolatile storage medium, wherein N is an integer greater than 1; judging whether an integrity check instruction sent by the host equipment is received or not; and if so, respectively calculating the checksum of each data copy in the nonvolatile storage medium, and returning a corresponding data integrity check result to the host equipment according to all the checksums. According to the invention, data integrity verification can be realized on the premise of reducing storage resource consumption. The invention furthermore discloses a data integrity verification system, electronic equipment and a storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of data storage, in particular to a data integrity verification method and system, an electronic device and a storage medium. Background technique [0002] Modern storage systems in today's data centers store data distributed across multiple storage devices. While storage devices are equipped with built-in firmware and hardware logic to perform data integrity checks, data can still be corrupted by various processing errors, such as transferring data over noisy wires or buses. [0003] There are data integrity verification schemes using end-to-end integrity checks in the related art, such as extending the transmission protocol including data integrity extension data and data protection information field data, but the above schemes consume a large amount of storage resources. [0004] Therefore, how to implement data integrity verification under the premise of reducing storage resource consumption i...
