Estimate IOPs Capacity

What is the best way to estimate the IOPS capacity of a given volume, assuming I don't have OnCommand tools available?

Cloud Miner -

No, but it can be calculated on an aggregate basis.

IOs on the aggr are shared by all vols on the aggr.

IOs Per Disk X # of Data Drives in the aggr.

Random IOs per disk type at 50% utilization:

SATA 75

FC/SAS 10K RPM 140

" 15K RPM 175

20 SAS @ 15k RPM = 3500 IOs on the aggr.

I hope this response has been helpful to you.

Just to add something to this. for some reason Microsoft work out IOPs in a different manner, normally IOPs per GB. Is there a way I can translate our NetApp storage from IOPs to IOPs/GB?

Thanks
