Abstract

The application provides a method, system and related device for determining a block number in a RAID6 array, and relates to the field of data storage. The method includes: receiving a request for obtaining the number of a target block; judging the RAID6 array according to the disk number and the stripe number Whether the target block number of the target block exists in the hash table; if yes, read the target block number from the hash table and respond to the number acquisition request; if not, judge whether the number of disks in the RAID6 array is an even number; if so, according to the target The symmetric block corresponding to the block determines the target block number. The present application does not need to calculate the block numbers in the RAID6 array one by one, which effectively improves the confirmation efficiency of the block numbers.

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 ...
