DiskSim is a *(resource), The DiskSim Simulation Environment.
From the home page:
<blockquote>
DiskSim is an efficient, accurate, highly-configurable disk system simulator
developed at the University of Michigan and enhanced at CMU to support research
into various aspects of storage subsystem architecture. It is written in C and
requires no special system software (just basic _(POSIX) interfaces). DiskSim
includes modules for most secondary storage components of interest, including
device drivers, buses, controllers, adapters, and disk drives. DiskSim also
includes support for a number of externally-provided trace formats and
internally-generated synthetic workloads, and includes hooks for inclusion in a
larger scale system-level simulator.
