RAID6 coding method and coding circuit

Abstract

The invention discloses an RAID6 coding method and a coding circuit. The method comprises the following steps: determining a first relational expression conforming to GF2 finite field characteristics based on a relationship between a first check code and a second check code in a preset Vandermonde RS coding relationship, wherein a first check code item in the preset Vandermonde RS coding relation is a first data item, a second check code item is a second data item, and a second relational expression of the first check code parameter and the second check code parameter is determined based on the first relational expression; determining a first check code parameter and a second check code parameter corresponding to different data strips in the GF8 finite field based on the first relational expression and the second relational expression, and generating a preset relational table; reading a first check code parameter and a second check code parameter corresponding to each data strip of the to-be-coded data from a preset relation table; and determining a first check code and a second check code corresponding to the to-be-coded data based on each data strip, the corresponding first check code parameter and the corresponding second check code parameter. The RAID 6 coding complexity can be reduced, and the coding efficiency can be improved.

AI Technical Summary

Benefits of technology

This patented describes how two checks are used in order to improve error correction codes (ECCs). One method involves comparing certain values stored within specific fields or blocks with those found outside these areas. If there're any differences indicating potential errors, it suggests modifying some parts of this field or block for better performance. Another approach uses only one set of checking rules instead of all them together. By doing both methods simultaneously, we aim to achieve more efficient ECDC decoding techniques by reducing redundancy across multiple components such as memory controllers and processors.

Problems solved by technology

This patented technical solution described in this patents relates to improving the performance of storing data with multiple disks connected together without losing any important files or even causing damage during power failures.
