Creating a thp/smart pool – HP XP P9000 Command View Advanced Edition Software User Manual
Page 47
You can create virtual volumes (THP/Smart volumes) from physical volumes that are grouped into
THP/Smart pools. You can then allocate those virtual volumes to hosts.
In the illustration below, note that the volumes used to create the THP/Smart pool are called THP/
Smart pool volumes. The THP/Smart pool is then used to provide capacity as needed to allocated
THP/Smart volumes.
THP/Smart pools are created by Device Manager, which automatically selects volumes based on
user-specified conditions. Users can also directly specify a volume to create a THP/Smart pool.
Users can also specify settings such as values for the usage rate threshold and reservation threshold.
If a Tiered Storage Manager license has been registered, user can use the Mobility tab to evaluate
and analyze the operation status that is related to a THP/Smart pool. When you delete an unnecessary
THP/Smart pool, THP/Smart volumes created from that pool are also deleted. For this reason, a
prerequisite to deleting a THP/Smart pool is that no THP/Smart volumes from that pool are allocated
to a host.
Creating a THP/Smart pool
You can create a THP/Smart pool using physical volumes. This provides more efficient use of physical
storage for virtual volumes allocated to hosts from the THP/Smart pool.
Before creating THP/Smart pools, you must:
•
Register the target storage system
•
When defining an external LDEV tier rank, a storage system that has multiple performance levels
must be externally connected
Verify the following when using XP24000/20000 and HP StorageWorks P9500 Disk Array for THP
pools:
•
Only parity groups from which volumes have already been created can be targets
Verfiy the following when using HP StorageWorks P9500 Disk Array for Smart pools:
•
Hardware tier: drive type and drive speed (RPM)
•
Only parity groups for each hardware tier from which volumes have already been created can
be targets
1.
On the Resources tab, select THP Pools under the target storage system.
2.
