Hard disk storage capacity has continued to rise whilst at the same time the cost per megabyte continues to fall. This, combined with increased usage of digital storage for documents, photography and video for both home and business use has led to increased need for reliable data storage system. Redundant arrays of inexpensive disks (RAID) have proven to offer the best characteristics for reliable storage. However, to date RAID based systems have been limited by their support for only single disk erasure tolerance.This paper introduces an efficient hardware RAID 6 controller on an FPGA capable offering support for uninterrupted access during double disk erasures and recovery.
