Estimate IOPs capacity with OnCommand Performance

Where can I view the IOPs capacity of a volume within OnCommand Performance?  I don't want to know how many IOPs are being served, but how many IOPS CAN be served for a specific volume.

Ryan -


There is no metric for estimated IOs on an aggr, but you can compute it.

See my reply to IOs on a volume:



Given that disk drive utilization on the aggr may be the key metric to monitor.

(<50% average is the Best Practice)

I hope this response has been helpful to you.

Re: Estimate IOPs capacity with OnCommand Performance

In OPM 7.0, there is a metric "Available IOPS" for node and aggr. which indicates the number of IOPS that can be added to the resource before reaching the maximum performance capacity.
