SLPR Storage Local Partition
Smart Tiers (Smart) In addition to Thin Provisioning functionality, this functionality places data on a
tier according to the I/O load. A data area that has a high I/O load is placed
in a high-speed hardware tier, and a data area that has a low I/O load is placed
in a low-speed hardware tier.
This document refers to the storage area that is created by using Smart as a
Smart pool, an actual volume that is one of the volumes making up a Smart pool
as a Smart pool volume, and a virtual volume that is created by a Smart pool
as a Smart volume.

Thin Provisioning
(THP) Functionality that allocates virtual volumes to a host, and uses the physical
capacity this is necessary according to the data write request.
This manual refers to the storage area that is created by using THP as a THP
pool, an actual volume that is one of the volumes making up a THP pool as a
THP pool volume, and a virtual volume that is created by a THP pool as a THP
volume.
THP/Smart pool An area where THP/Smart pool volumes (actual volumes) are registered. When
a THP/Smart volume (virtual volume) has a write operation from a host, that data
is stored in a THP/Smart pool volume.
THP/Smart pool
volume An actual volume that is one of the volumes making up a THP/Smart pool.
THP/Smart volume A virtual volume created from a THP/Smart pool (that is, is associated with a
THP/Smart pool).
