Abstract

The present invention provides a method, system, device and storage medium for improving the speed of disk address conversion. The method includes: setting each block of a plurality of stripes on the disk according to a preset rule to generate a random matrix; The disk address and the first disk code of the block, and determine the offset according to the disk address; determine the first block code corresponding to the first disk code in the reference stripe, and determine the first block code according to the first block code, calculating the offset and the stripe width to obtain a second block code; and determining a second disk code corresponding to the second block code in the reference stripe, according to the first disk code and the first disk code The second disk code determines the stripe number of the block to be converted, and outputs the second block code and the stripe number. The invention improves the solution speed of address conversion by realizing the regularization of array logical addresses.

Description

technical field [0001] The present invention relates to the field of magnetic disks, and more specifically refers to a method, system, device and storage medium for improving the speed of disk address translation. Background technique [0002] Redundant arrays composed of independent disks are widely used in storage systems. Redundant disk arrays contain redundant disks, namely hot spare disks. The task replaces the bad disk, and the array containing the hot spare disk is called DRAID. Briefly introduce a way of array space distribution: the disk array consists of 10 disks. Wherein, each stripe is composed of a data block Di and parity disks P and Q. The data block check blocks in the stripe are sorted sequentially. After the first stripe stride 0 is full, continue to arrange the data blocks and check blocks of the next stripe. Among them, the Q verification disk is larger than other disks. This is to meet the requirements of the verification algorithm. Such a spatial di...
