HP XP P9000 Performance Advisor Software - Manual (Page 221)

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 Details table.
An informational message on the VVol settings that you configured appears under the Pool
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.
Viewing Smart pool capacity
In addition to the configuration and performance data, you can also view the capacity details for a
Smart pool. Click a record in the Pool Information table to view the following details:
Description Column names
Displays the tier levels for the selected Smart pool. Each tier level can be assigned to one of the
following drive types:
• SSD
• SAS
• SATA
For example, tier level 1 can be assigned to the SSD drive type, tier level 2 can be assigned to
the SAS drive type, and tier level 3 can be assigned to the SATA drive type.
Pool Tier
Displays the total capacity of a tier level. Total Capacity
Displays the amount of tier space that is already utilized. Used Capacity
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 292.
