HP XP P9000 Performance Advisor Software v5.5 User Guide (T1789-96337, Februrary 2013)

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
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:
DescriptionColumn names
Displays the tier levels for the selected Smart pool. Each tier
level can be assigned to one of the following drive types:
Pool Tier
• SSD
• SAS (15 krpm)
• SAS (10 krpm)
• SAS (7.2 krpm)
• External (Low)
• SATA (7.2 krpm)
• External (High)
• External (Mid)
• Coexistence
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.
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” (page 261).
