Viewing performance charts to compare volumes or LUNs that are in the same QoS policy group

You can view the volumes and LUNs that are in the same QoS policy groups and then compare the performance on a single IOPS, MB/s, or IOPS/TB chart to identify any issues.

1. In the left navigation pane, click Storage > Volumes.
   The Health: All Volumes view is displayed by default.
2. In the View menu, select Performance: Volumes in QoS Policy Group.
3. Click the name of the volume that you want to review.
   The Performance Explorer page is displayed for the volume.
4. In the View and Compare menu, select Volumes in same QoS Policy Group.
   The other volumes that share the same QoS policy are listed in the table below.
5. Click the Add button to add those volumes to the charts so that you can compare the IOPS, MB/s, IOPS/TB, and other performance counters for all the selected volumes in the charts.
   You can change the time range to view the performance over different time intervals other than the default of 72 hours.
