Optimizing data placement in a THP/Smart pool
Data placement can be optimized in a THP/Smart pool.
Prerequisites
•
A Tiered Storage Manager license must be registered.
•
An HP XP7 Performance Advisor license must be registered (when referencing performance inform-
ation).
•
Ensure that Smart pools are being monitored (when referencing Performance Utilization, IOPS for
a hardware tier, or View Tier Properties).
1.
From the tree view of the Mobility tab, select THP Pools.
2.
Select THP Pool to check for THP/Smart pools whose usage rate, reservation rate, or performance
usage rate is high.
3.
If a THP/Smart pool does not meet the expectations for capacity or performance, click the link
of the THP/Smart pool in the ranking.
4.
Check the usage status and performance of each hardware tier in the THP/Smart pools by
performing the following:
• To check if the usage capacity of the THP pool is appropriate, from the Actions menu, select
Show Trend Chart, and then check the IOPS and usage capacity of each pool.
• To check if the configuration and performance of each hardware tier in the Smart pool is
appropriate, from the Actions menu (or from the Capacity & Performance Utilization link),
select Show Trend Chart, and then check the capacity and performance of each hardware
tier. To save the contents of the Trend Chart as a report, click Export to CSV and save the
contents as a CSV file to a location of your choice.
• To check page access distribution per average number of I/O operations, from the Actions
menu, select View Tier Properties.
5.
Select the THP/Smart volumes that have a problem and optimize the data placement by clicking:
• Migrate Data
• Edit Tiering Policy
• Expand THP Volume, or one of the other buttons

On the Mobility tab, select THP Pools to confirm data placement optimization.
