【Abstract】 In this paper, a synthesized trace & I/O request generator are designed and implemented to measure,simulate and evaluate computer storage subsystem. The characteristics of I/O workload are discussed and be used to synthesize the trace. Additionally, the Dual-clock design method is introuduced to implement I/O generation timing & I/O response time counting . The results of measuring SSD-HD-MO storage subsystem are also given in this paper.更多还原
