Abstract
In order to understand the fundamental performance of storage subsystem, an analytical model for the serial storage interfaces with the spatial reuse feature is derived. Based on this model, the maximum aggregate throughput from different system configurations and load distributions is investigated. Result shows how the number of disks needed to saturate a loop varies with different number of hosts and different load scenarios. It also shows how the load balancing by uniformly distributing the load to all the disks on a loop may incur high overhead. These results show the achievable throughput may be reduced by more than half in some cases.
