Abstract
A RAID controller includes a cache memory in which write cache blocks (WCBs) are protected by a RAID-5 (striping plus parity) scheme while read cache blocks (RCBs) are not protected in such a manner. If a received cache block is an RCB, the RAID controller stores it in the cache memory without storing any corresponding parity information. When a sufficient number of WCBs to constitute a full stripe have been received but not yet stored in the cache memory, the RAID controller computes a corresponding parity block and stores the RCBs and parity block in the cache memory as a single stripe.
