The Serial Storage Architecture and Fibre Channel-Arbitrated Loop interfaces offer a simple cabling system, higher bandwidth, the ability to connect more than 100 disks, fault tolerance, and fair accesses on the channel. This article investigates the performance of these two emerging serial-storage interfaces for fairness, latency, overhead, and aggregate throughput under various traffic loads.
