Post subject:  Discrepency between System Performance IOPS and All VVs IOPS

Hi,

I have created an Exported Volumes Compare by Performance report based on all objects.

You can see the result here.

As you can see the current IOPS for all the object is about 12500 IOs/Sec.

I was expecting this figure to be match with the figure I get in the dashboard's IOPS Performance widget but it is not !
Can someone explain to me why ?

Thanks

At a guess the system performance might include backend IO like RAID, rcopy target volumes and background rebalancing etc tasks.

The exported volume performance will exclude those numbers, also you're looking at averaged for the day data from volumes vs hires single day system data.
