This article examines two emerging serial storage interfaces, Serial Storage Architecture and Fibre Channel-Arbitrated Loop. The advantages of these two emerging standards include simple cabling system (serial instead of parallel); higher bandwidth; ability to connect a large number (more than 100) of disks; fault tolerance; and fair accesses on the channel. The authors intend to find the performance limitations and characteristics of these two interfaces. They have investigated the performance of both SSA and FC-AL in terms of fairness, latency, overhead and aggregate throughput under three types of traffic load: light, heavy, and based on a trace log from a database application.
