Abstract

The invention discloses an RAID 6 hardware acceleration circuit structure, which comprises: a parameter analysis module, which is configured to be used for acquiring a parameter coefficient of an RAID 6 algorithm and calculating an operation coefficient based on the parameter coefficient; a data caching module, which is configured to be used for storing disk data; and a finite field operation module, which is configured to be used for sequentially obtaining the operation coefficient and the disk data corresponding to the current disk, and performing finite field multiplication on the basis of the operation coefficient and the disk data corresponding to the current disk to obtain an intermediate value of the current disk, wherein the finite field operation module is further configured to be used for caching the calculated intermediate value of the first disk to the intermediate value storage module, performing XOR operation on the calculated intermediate values of other disks and values in the intermediate value storage module, caching an operation result to the intermediate value storage module, and if the current disk is the last disk, outputting the value in the intermediate value storage module as a final result. The invention further discloses an RAID 6 hardware acceleration implementation method.

Description

technical field [0001] The invention relates to the technical field of hardware circuits, in particular to a RAID 6 hardware acceleration circuit structure and a RAID 6 hardware acceleration implementation method. Background technique [0002] RAID 5 is a storage solution that balances storage performance, data security, and storage cost. RAID 5 can be understood as a compromise between RAID 0 and RAID 1. RAID 5 can provide data security for the system, but the degree of protection is lower than that of RAID 1 and the utilization rate of disk space is higher than that of RAID 1. RAID 5 has a data reading speed similar to that of RAID 0, except that there is one more parity check information, and the speed of writing data is slightly slower than writing to a single disk. At the same time, because multiple data correspond to one parity check information, RAID 5 has a higher disk space utilization rate than RAID 1, and the storage cost is relatively low, so it is a solution t...
