ABSTRACT:
A performance optimized RAID Level3storage access controller with a unique XOR engine placement at the host
etwork side of the cache. The invention utilizes multiple data communications channels and a centralized cache memory in conjunction with this unique XOR placement to maximize performance and fault tolerance between a host network and data storage. Positioning the XOR engine at the host
etwork side of the cache allows the storage devices to be fully independent. Since the XOR engine is placed in the data path and the parity is generated in real-time during cache write transfers, the bandwidth overhead is reduced to zero. For high performance RAID controller applications, a system architecture with minimal bandwidth overhead provides superior performance.
