Secure Sockets
Layer (SSL)

A common protocol for managing the security of message transmission over the
Internet.
Two SSL-enabled peers use their private and public keys to establish a secure
communication session, with each peer encrypting transmitted data with a
randomly generated and agreed-upon symmetric key.

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.

SNMP

SSD

Solid-state drive

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

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

THP/Smart pool
