[Disksim-users] simple disk approximation ...

[Greg Ganger]

Disk specs can be created by manipulating the parameters, as described
in the manual.  The "duplication" you mention relates to two independent
regions of parameters: one relates to the disk model and the other to
the synthetic workload generator.

Good luck,

Greg
