| Abstract: | With an embedded processor, I/O controller can offload the major I/O processing workload form the CPU, and increase the I/O performance. This paper addresses the essential issue in the design of parallel disk scheduling for RAID-10 devices. This paper explores multi-disk scheduling for I/O requests, using a novel fuzzy function. The new scheduling method can improves the response times of the request, and also improves the load balance performance of the system |
