Hello,

I believe this topic should shed some light on the observed behavior > utilization >1hr flattening min/max/avg values

Let me know if that helps!

You can justify that by the number of alarms triggered for IOPs, also you can suggest to review the trend, since in your case it is going up. On a side note, can you please tell us what is the reason for this spike? Any scheduled activity?

Hi jingtai,
As described in the linked topic you should have 2-hours averages for the historical periods. If those values are high during working hours and you have lots of alarms triggered, you can explain your boss that you need an upgrade. But if those averages are not that high and you just had some spikes I would try to find out the reason to balance them in future.
Thanks!

i am manage the citrix xendesktop (300 active users ), boot storm and login storm may cause this spike. reboot cause 500-600 IOPS per vm guest.

Ok, this explains it, any user-related activity (such as massive log in/backup) or a reboot can cause resource usage spikes, but during the normal activity this should not cause any issues, right?
