got ya, so sorry, It's been so many years since I've done any kind of
benchmark, we used a tool back in the day that generated data, then read
that data back over and over, the problem today, is I don't think
there's so much control over the DASD subsystem as there was when I was
benchmark spinning DASD or RVA's
we'd make sure we'd clear cache, turn off cache, DFW and run some
benchmarks, then do the same on the new subsystem(s)
maybe someone here still performs DASD benchmarks and can offer a solution

Not so much as to where to find the statistics. Rather, a set of benchmarks to
produce the statistics. Thanks.

IIRC - the RMF/SMF record type 74-5 can you provide the I/O rates, Cache
Statistics.....etc

I have been asked for ideas in regards to DASD benchmark testing. We would like
to compare IBM DS88xx's against competitors. Something that would generate
statistics for I/O rate, response time, and exercise track change rate
(replication performance).
Something free of course. Thanks in advance.
