HP StorageWorks P9000 Performance Advisor Software v5.3 User and Troubleshooting Guide (T1789-96322, August 2011)

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 V-volumes

sort by IOPS.

Displays the maximum storage that is accepted on a particular tier level. You will have set this

capacity threshold value on the P9000 disk array.

Capacity Threshold

To understand how different tiers are utilized by a Smart pool, compare the utilization of individual

RAID groups that constitute the Smart pool. You can see the utilization of individual RAID groups and

also the overall utilization of all the RAID groups. You must determine the drive types of the individual

Raid groups that constitute the Smart pool. Also, you need to know the RAID group for which you

want to determine the drive type. The RAID groups are listed under Pool Volumes in the Pool Details

table. For more information on identifying the drive type for a RAID group, see “Drive types navigation

path” on page 296.
