A METHOD FOR CALCULATING RAID5 PARITY CODE ON INTERLEAVING AND OUT OF ORDER DATA STREAMS, AND A SYSTEM USING THE SAME

摘要

A storage system for constructing RAID on the basis of flash memory comprises: one or more RAID processors and a plurality of flash memories. The RAID processor comprises a plurality of read-and-write processing units, a data block pointer unit, a data block counter and a parity check code buffer. One read and write processing unit can control one or more flash memory units. A method for constructing RAID in a storage system on the basis of flash memory can realize the function of RAID in a very small logic area and approximately negligible time and realize the unification of the function and performance of a storage system such as an enterprise-level SSD.
