cartridges to a logical library by using
beginning and ending volume serial
number ranges that are set by the user.
cartridge cache
Non-HD slots (Tier 0) selected as
preferred locations for frequently used
cartridges. The library firmware tracks the
most recent usage of each cartridge as a
means to arbitrate which cartridges
should be maintained in the cartridge
cache.
cartridge gripper
An electromechanical device on the
cartridge accessor of the TS3500 Tape
Library that gets or puts cartridges from
or to a storage slot, tape drive, or I/O
station. Two grippers (Gripper 1 and
Gripper 2) are located on the pivot
assembly of the accessor. One gripper can
grip a single cartridge.
cartridge inventory time
The amount of time required for the
TS3500 Tape Library to determine
whether each cartridge storage slot in the
library is empty or full.
cartridge manual rewind tool
A device that can be fitted into the reel of
a cartridge and used to rewind tape into
or out of the cartridge.
cartridge memory
See LTO cartridge memory .
cartridge move time
The time required for a cartridge accessor
to pick a cartridge from a slot (or drive),
move the cartridge to a drive (or slot),
pivot (if required), and insert the
cartridge into the drive (or slot).
cartridge storage slot
One of several containers that are
mounted inside the frames of the TS3500
Tape Library and are used to store tape
cartridges. See also
HD slot .
caster One of four wheels that are mounted in
swivel frames and used to support the
weight of the TS3500 Tape Library.
CETool
CETool is a software program that is used
by IBM Service personnel (also known as
customer engineers or CEs) to update
library and drive firmware, configure the
Call Home program for the TS3500 Tape
Library, collect library and drive logs,
backup and restore the configuration for
non-volatile random access memory
(NVRAM), and perform other
service-related tasks.
cell top cap
Located on each column of storage slots
within the TS3500 Tape Library, a plastic
component to which a bar code label
holder can be attached. The library uses
the bar code label to establish the
boundary of a logical library.
circuit board
A thin plate on which chips and other
electronic components are placed.
Computers consist of one or more boards,
often called cards or adapters.
cleaning cartridge
A tape cartridge that is used to clean the
heads of a tape drive. Contrast with
data
cartridge .
clearance
The distance by which one object clears
another or the clear space between them.
compression
The process of eliminating gaps, empty
fields, redundancies, and unnecessary
data to shorten the length of records or
blocks.
configure
To describe to a system the devices,
optional features, and programs installed
on the system.
controller
A device that coordinates and controls the
operation of one or more input/output
devices (such as sensors and actuators),
and synchronizes the operation of such
devices with the operation of the system
as a whole.
control path
(1) Designated by the operator of the
TS3500 Tape Library, a logical path into
the library through which a server sends
standard SCSI Medium Changer
commands to control a specific logical
library.
(2) A tape drive that is designated by the
operator of the TS3500 Tape Library to
manage communication to and from a
server and the library.
