Abstract: This paper analyzes the net topology of FC-SW Storage Area Network(SAN), advances the I/O addressing flow in FC-SW SAN, and predicts the performance of storage subsystem in FC-SW SAN based on queue theory. It describes the impact on I/O response time made by disk cache hit rate, probability of read/write disk, and network FC switch performance.
