METHOD AND APPARATUS FOR CACHING BLOCKS OF REDUNDANT ARRAY OF INDEPENDENT DISKS, AND DEVICE AND READABLE MEDIUM

WIPO Patent Application WO/2024/046213

A1

Provided in the present application are a method and apparatus for caching blocks of a redundant array of independent disks, and a device and a readable storage medium. The method comprises: determining the number of blocks in each stripe in a disk array, and constructing stripe cache information structural bodies; applying for an internal memory from a fixed object pool according to the number of blocks in each stripe; in response to the disk array performing a read io process, according to an array address of the read io process, calculating a stripe serial number and a block serial number, where data to be read is located; and calculating a pointer variable of a stripe cache information structural body that corresponds to the block serial number in a cache structure corresponding to the stripe serial number, and reading the data on the basis of the pointer variable. By using the solution of the present application, the internal memory cost of disk arrays can be effectively saved on, the performance of storage systems is improved, and the competitiveness of products is improved.
