Abstract

The invention provides a method, a system and a related device for determining a block number in an RAID6 array, and relates to the field of data storage, the method comprises the following steps: receiving a number acquisition request of a target block; judging whether a target block number of a target block exists in a hash table corresponding to the RAID6 array or not according to the disk number and the strip number; if yes, reading the number of the target block from the hash table and responding to the number acquisition request; if not, judging whether the number of disks of the RAID6 array is an even number or not; and if yes, determining a target block number according to the symmetric blocks corresponding to the target block. According to the method, the block numbers in the RAID6 array do not need to be calculated one by one, so that the confirmation efficiency of the block numbers is effectively improved.

Description

technical field [0001] The present application relates to the field of data storage, in particular to a method, system and related device for determining a block number in a RAID6 array. Background technique [0002] The typical representative of RAID (Redundant Array of Independent Disks) is RAID6. RAID6 is an array composed of 4-16 disks, and there are two hot spare disks in the array. Data integrity is maintained when two disks are removed from the array at the same time. However, when it is necessary to determine the block number in the array, it is necessary to give the disk number and the stripe number each time, and calculate the block number once, which makes the process of determining the block number complex and time-consuming. Contents of the invention [0003] The purpose of this application is to provide a method for determining block numbering in a RAID6 array, a system for determining block numbering in a RAID6 array, a computer-readable storage medium and ...
