Title:
DISK ARRAY WRITE PROCESSING METHOD AND APPARATUS, DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/098885
Kind Code:
A1
Abstract:
The present application discloses a disk array write processing method and apparatus, a device, and a medium, which are applied to the technical field of data storage. The method comprises: on the basis of an IO write request, determining a target stride to which data is to be written in DRAID5 and write location information of a target data block to which data is to be written in the target stride; respectively recording the write location information of the target data block in each target stride to a corresponding information record; on the basis of the information record, determining total location information, of a check block in each target stride, on which data updating is to be performed; when any target stride meets a check data reading condition, performing primary data reading from a corresponding check block on the basis of current total location information so as to obtain old check data corresponding to the current total location information; performing calculation on the basis of the old check data to obtain new check data; and writing the new check data to the corresponding check block on the basis of the total location information. The time spent processing check data can be reduced, so that the storage performance is improved.
