T
TapeAlert
A patented technology from
Hewlett-Packard that monitors the status
of a tape device and media, and detects
problems as they occur.
TapeAlert flags
Status and error messages that are
generated by the TapeAlert utility and
display on the host console. The messages
indicate the type of problem and tell how
to resolve it.
tape cartridge
A removable storage device that consists
of a housing containing a belt-driven
magnetic tape wound on a supply reel
and a takeup reel.

target A SCSI device that performs an operation
requested by the initiator. A target can
also be an initiator.
TB Terabyte.

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 used to end a SCSI bus.
(2) A single-port, 75- 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 usually 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.
Total Productivity Center (TPC)
See IBM Total Productivity Center.
touch keys
On the touchscreen of the TS3500 Tape
Library, 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.
