Abstract: Combined with the application of the storage array, the RAID system is achieved based on the Intel 80321 I/O processor. And the optimization of RAID5 system is put forward as follow: the implication of the application accelerator unit and the management strategy of the cache. It is proved that the performance of the system meets the expectations.
