Configuring VVol settings
You can configure the following VVol settings:
•
The maximum number of VVol records you want to view.
NOTE: HP recommends viewing a maximum of 150 records at a time, so that there is no
performance impact.
•
The metrics based on which you want to sort the records. You can sort records based on the
IOPS, MBPS, Backend Tracks, and the Avg Read/Write Resp Time metrics.
By default, the VVol records are sorted based on the Avg Read/Write Resp Time values.
To configure the above-mentioned settings, click V-vols Settings in the Pool <Pool ID> Details table.
An informational message on the VVol settings that you configured appears under the Pool <Pool
ID> Details table header. For example, if you selected a maximum number of 30 VVol records and
the sorting to be based on the IOPS, the following informational message appears: Top 30 Pool
