Problems solved by technology

As far as this approach is concerned, the CPU may often be rate-limiting the data store since the processing related to ECC can be variable and time-consuming
In other words, processing in the CPU can cause bottlenecks and increase latency

Abstract

A redundant array of independent disks (RAID) system comprises N storage arrays. Each of the N storage arrays comprise a target processing module and 1 to M hard disk drives, where M and N are integers greater than 1. A data processing module assigns a first data storage request for a first data block to one of the target processing modules for processing of error checking and correcting (ECC) data for the first data block. The one of the target processing modules sends a first portion of the first data block and ECC data associated with the first data block to another of the target processingmodules.
