【Abstract】 I/O response time is an important parameter to evaluate the storage system’s performance. Based of FC- RAID in SAN en- vironment, this paper evaluates the effect of different prefetch policies on the I/O response time of RAID by queue theory, and put forward the technique to improve the performance of storage system.更多还原
