Why are IOPS higher or lower compared to other volumes in last 30 days vs 180 days?

Last Updated:

Applies to

  • ONTAP 9
  • Active IQ Unified Manager (AIQUM)


  • A limitation of Active IQ Unified Manager (AIQUM) is that viewing a range greater than 30 days has hourly averages instead of 5-minute averages
  • That loss of granularity means a spike lasting a few minutes would show a higher maximum IOPS, but would show less since the IOPS average out for that hour
  • The maximum for 30 days would be the highest 5-minute average, but the maximum of 180 days would be the highest of the hourly averages
  • Any identification of where the IOPS are coming from must happen from the user, application, or client side and not the storage
