The next test, Iometer, was added to benchmark the multi user environment and simply stated; it is both a workload generator and a measurement tool. Iometer measures performance under a controlled load measuring I/Os at varying depths. Iometer will be used with two of the better known scenarios, the File Server and Database patterns. A lot of information can be extrapolated from this such as Total MB/s, Average I/O Response times, and more. The patterns of File Server and Database will be run at a depth of 1 – 128 I/Os in a doubling fashion (1, 2, 4, 8, 16, 32, 64, and 128).
