Standards that define I/O buses primarily intended for connecting storage systems
and devices to hosts through host bus adapters.

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.

THP pool volume, and a virtual volume that is created by a THP pool as a THP
volume.
