Hello all
I'm currently trying to understand a performance problem I encountered this morning on my 7200C
the 7200C has 42FC disks , and should be able to run around 5500IOPS
This morning, service time was not good at all, and I had 10.000iops , max 12.000
This increase of IOPS was caused by a high total bandwith : around 200MBPS

Then, I'm trying to find which VV was responsible for a high bandwith and I tought the report "Exported Volumes Compare by Performance" could help :

unfortunately , the sum of the bandwith of each exported volume is around 100MB, when I expect 200MB
Am I doing something wrong ?
My goal is to find which host, or which exported volume can be the responsible of the high total BW
with CLI, statvlun -hostsum could help me to find the BW for each host. But now the problem is over, and I suppose we cannot check in the past with CLI
