Virtualizing storage capacity (THP/Smart)
This module describes how to virtualize storage capacity.
About virtualizing storage capacity
HP StorageWorks P9000 Thin Provisioning (THP) provides virtual volumes to a host and allocates the
actual capacity from a THP pool when a host makes a write request. By using THP pools, you can
allocate more capacity to a host than that allowed by the actual physical configuration of the storage
system.
THP pools provide the following advantages:
• You can reduce system setup and operational costs.
• You can use resources more efficiently.
• You can distribute workload equally among volumes.
Smart Tiers (Smart) improves THP pools storage performance further by taking advantage of
performance differences between hardware tiers.
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 parity groups to create a THP/Smart pool.
