ABSTRACT::
  We implemented a detailed model of the HP 97560 disk drive, to
replicate a model devised by Ruemmler and Wilkes (both of
Hewlett-Packard, HP).  Our model simulates one or more disk drives
attached to one or more SCSI buses.  The design is broken into three
components: a test driver, the disk model itself, and the
discrete-event simulation support.  Thus, the disk model can be easily
extracted and used in other simulation environments.  We validated our
model using traces obtained from HP, using the same "demerit" measure
as Ruemmler and Wilkes.  We obtained a demerit percentage of 3.9%,
indicating that our model was extremely accurate.  This paper
describes our implementation, and is meant for those wishing to use
our model, see our validation, or understand our code.
