library. These tools are identical to those
tools provided by the IBM TS3000 system
console (TSSC), an externally
rack-mounted system console.
target A SCSI device that performs an operation
that is requested by the initiator. A target
can also be an initiator.
TB Terabyte.
TCP/IP
See transmission control protocol/Internet
protocol .
terabyte
1 000 000 000 000 bytes.
terminate, termination
To prevent unwanted electrical signal
reflections by applying a device (a
terminator) that absorbs the energy from
the transmission line.
terminator
(1) A part that is used to end a SCSI bus.
(2) A single-port, 75-
Ω
device that is used
to absorb energy from a transmission line.
Terminators prevent energy from
reflecting back into a cable plant by
absorbing the radio frequency signals. A
terminator is shielded, which prevents
unwanted signals from entering or valid
signals from leaving the cable system.
tier The depth of a cartridge location in an
HD slot.
Tivoli Storage Manager (TSM)
An IBM client/server product that
provides storage management and data
access services in a heterogeneous
environment. TSM supports various
communication methods, provides
administrative facilities to manage the
backup and storage of files, and provides
facilities for scheduling backups.
Tivoli Storage Productivity Center (TPC)
A software solution that manages storage
infrastructures in Open Systems
environments.
topology
In communications, the physical or logical
arrangement of nodes in a network,
especially the relationships among nodes
and the links between them.

touch keys
On the touchscreen of the , an array of
small, touch-sensitive keypads that lets
you select and navigate through menus.
To acknowledge that it has been pressed,
a touch key initiates an audible beep (if
enabled) whenever you press it. The
audible beep is the default.
touchscreen

TPC See IBM Total Productivity Center .
track A linear or angled pattern of data written
on a tape surface.
transfer rate
See data transfer rate .
transmission control protocol/Internet protocol
(TCP/IP)
(1) The Transmission Control Protocol and
the Internet Protocol, which together
provide reliable end-to-end connections
between applications over interconnected
networks of different types.
(2) The suite of transport and application
protocols that run over the Internet
Protocol.
TS4500 management GUI
A web-based interface that allows users to
configure, administer, monitor, and
manage the TS4500 tape library locally
from the IMC or from a remote location.

console (IMC) .
TSM See Tivoli Storage Manager .
TSSA See Tape System Service Application .
two-node arbitrated loop
In Fibre Channel technology, the
connection of two nodes that
communicate directly (without the use of
a switch) and use the same protocol.
two-node switched fabric loop
In Fibre Channel technology, the
connection of two or more nodes that
might not use the same protocol and
communicate by using a switch.
two-phase power
Pertaining to the TS4500 tape library,
electricity that is transmitted via three
wires (line, line, and ground), with a
