Optimizing data placement in a THP pool
Data placement can be optimized in a THP pool.
Follow this procedure to optimize your data placement:
1. From the tree view of the Mobility tab, select THP Pools.
2. Expand the THP Pools tree to check for THP pools whose usage rate, reservation rate, or
performance usage rate is high.
3. If a THP pool does not meet the expectations for capacity or performance, click the link of the
logical group name in the ranking.
4. Check the usage status of the THP pools. For Smart Tiers Software pools, also check the usage
status and performance for each hardware tier. Select the THP volumes that have a problem and
optimize the data placement by clicking any the following buttons:
• Migrate Data
• Edit Tiering Policy
• Expand Pool
• Reclaim Zero Pages
5. Select THP Pools from the Mobility tab to check optimization of the data placement.
Setting the schedule for executing the monitoring and relocation of Smart Tiers pools
Monitoring and relocating of Smart Tiers Software pools can be scheduled by:
1. From the Mobility tab, select THP Pools.
2. Expand the tree view and select the target storage system. Then from the list of THP pools, select
the Smart Tiers Software pool for which the schedule is to be set.
3. Click the Edit Pool button.
4. In Smart Tiers Software Settings in Tier Management select the Custom radio button and click the
Create Template button. If templates have already been created, select a template.
5. Specify the necessary items by following the instructions in the window and create and execute
the plan.
6. View a list of tasks to make sure that all tasks completed.
7. In the Mobility tab select the Smart Tiers Software pool. Then from Tier Management in Summary
confirm the template names.
Data migration
This module describes data migration.
About data migration
Data migration involves moving data from one set of volumes to another set of volumes or THP pools,
including those in externally-connected storage systems. For example, you can migrate data when
your volume performance decreases or your environment changes. When relocating data based on
the results of performance monitoring for volumes being used by servers and applications, or when
migrating data from an old storage system to a newly set-up storage system, the data in multiple
volumes can be migrated to other volumes or pools.
