A Stochastic Disk I/O Simulation Technique

In this paper, we describe a technique to construct accurate stochastic simulation models from acquired trace data. The resulting simulation models accept input trace data and return estimates of disk request service times. In addition, we describe a trace collection technique capable of collecting accurate trace data from Novell Netware servers. These traces are used to construct a simulation model of a Novell Netware I/O subsystem that is used to study the impact of disk data reorganization on I/O performance.
