This paper discusses an I/O architecture and key techniques of RAID controller.The main target is insert the request of the RAID module which have split user request into single disk R/D into corresponding I/O disk queue.According the priority and read/write characteristic,we adjust the requests order in response request queue or combination the fore-and-aft small requests into a big request,consequently we implemented the scheduler policy of I/O requests.
