Script to simulate I/O on HP-UX

roadrunner_1 — Thu, 20 Jul 2006 04:07:19 GMT

I am performing tests to evaluate both HP and EMC storage arrays.
I need a script to simulate or generate random I/O activity upto 10000 IOPS with the following profile - 50% reads/50% writes and 80% reads/20writes.

Can somebody please provide me with a script, which will do the above? I will be glad to share the test results. Test are being performed this Monday 7/24.

Hi,

Try with IOMeter, http://www.iometer.org/

As there is no port for HP-UX, you need to do it by yourself.

Shalom,

This can totally be simulated with the dd command.

IOzone is another good tool for this:

I'll second Duncan's advice. I've used iozone before. its fairly painless, and can produce some nice excel-formatted graphs.
