io size depends on what your application is doing, probably need to look on the array side.

Thanks for the response - powermt display every=10 does give me IO/Sec after the first sample.

How does this equate to throughput or latency?

Is the IO a Linux IO (512-byte) or a standard FC IO (I think 2048 bytes)?

I'm trying to determine the load on these HBAs...

you can try "powermt display dev=all every=10"  ..or powermt display every=10"

Very fast SAN - too much for this environment at the current time.

Looking at potentially removing this DB from this SAN - to what type of storage is the question.

That's why I'm trying to get these stats...

Thanks to your help, this seems to work very well:

powermt display every=5 | grep qla | awk '{now=strftime("%d-%b-%Y,%T"); print now " " $0}'

Thanks.

This is an Oracle DB using ASM.

I would expect the latency to be near 0 (on the order of ~2ms) if the Q-IOs are near or at 0, correct?

to me latency = response time , 2ms is awesome
