Creating a THP/Smart pool
You can create an THP or Smart pool, which provides more efficient use of physical storage for virtual
volumes that are allocated to hosts from the THP/Smart pool.
Prerequisites
• Register the target storage system.
• When defining an external LDEV tier rank, externally connect a storage system that has multiple
performance levels.
• Verify the following when using HP XP24000/20000 and HP XP P9500 Storage for THP pools:
• Parity groups from which volumes have already been created can be added
• Drive type characteristics (for example: drive type and drive speed) in parity groups and RAID
level
NOTE:
In Smart pools, if different drive types and/or RAID levels are mixed in a single tier, they will all be
considered equal for data placement regardless of page access frequency. As a result, I/O performance
will be dependent on the drive type characteristics and RAID level on which any given page resides.
NOTE:
In THP pools, if different drive types and/or RAID levels are mixed in an THP pool, I/O performance
will be dependent on the drive type characteristics and RAID level on which any given page resides.
1. On the Resources tab, expand the storage system, list existing THP Pools, and click Create Pool.
NOTE:
You can also click General Tasks > Create Pool.
2. In the Create Pool dialog box, add a pool name, and optionally select Reflect this pool name to
the storage system.
3. To configure an THP or Smart pool, select THP and configure the following:
1. In Additional Parity Groups, click Add Parity Groups.
2. Select one or more parity groups, click Add to Pool, and then click Close. The Pool Summary
is updated.
3. (Optional) Click Advanced Options to configure Pool ID, Used Threshold, and Subscription
Thresholds as needed.
