Abstract : Under Windows operating system, existing I/O benchmarking tools does not allow a developer to efficiently define a file access strategy according to the applications' constraints. This is essentially due to the fact that the existing tools do allow only a restricted set of I/O workloads that does not generally correspond to the target applications. To cope with this problem, we designed and implemented a precise I/O simulator allowing to simulate whatever real I/O trace on a given defined architecture, and in which most of file and disk cache strategies, their interactions and the detailed storage system architecture are implemented. Simulation results on different workloads and architectures show a very high degree of precision. In fact, the mean error rate as compared to real measures is of about 6% with a maximum of 10% on global throughput.
