DATA WRITING METHOD AND APPARATUS, DATA READING METHOD AND APPARATUS, AND DEVICE, SYSTEM AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/000670
Kind Code:
A1
Abstract:
Disclosed in the present application are a data writing method and apparatus, a data reading method and apparatus, and a device, a system and a medium. The method comprises: a network controller performing erasure code encoding on original data, and writing, into a storage node, a third number of target data blocks of a plurality of obtained target data blocks; the network controller reading, from the storage node, a first number of target data blocks of the third number of target data blocks, and decoding the read target data blocks, wherein the plurality of target data blocks comprise a first number of original data blocks and a second number of parity data blocks, the same version information is contained at two ends of the target data block, and the third number is greater than the first number. By means of the present application, computation overheads, which are originally of a central processing unit, can be offloaded to a network controller, such that the consumption of the central processing unit is reduced, and the data processing efficiency is improved; and version information is contained at two ends of a target data block, such that the data validity is ensured.
