tape drive
Glossary-7
put
An activity in which a robot places a cartridge into a slot or drive.
RE
See redundant electronics (RE) .
RIM
See robotics interface module (RIM) .
rail
(1) That portion of the upper robot track assembly that provides power and
communication to the robot. (2) All of the cartridge slots and drives accessible through
a rail.
redundant electronics (RE)
A feature that provides failover protection in enterprise libraries. RE uses a two sets of
library controller cards. At any given time, one set is active and the other set is
standby. The active library controller can failover to the standby in response to a
command from ACSLS or the SLC. Automatic failover can be initiated by the library if
a library card failure.
robot
A mechanism that moves horizontally along a track to transport tape cartridges to and
from other locations in the library.
robotics interface module (RIM)
The module containing the curved rails and pass-thru port (PTP) assemblies.
selected slot
A storage slot that cannot currently be used for cartridge storage, but will be made
active automatically by the library controller when activated capacity is increased.
service area
An area between the access doors of the customer interface module and the safety
barrier. In the service area, a redundant or inoperable robot can be stored for service
and other mechanisms can be repaired or replaced.
service safety door
A motor-driven barrier that lowers and raises. This door separates the service areas of
the front interface assembly from the rest of the library. The SSD allows service
personnel to safely repair or replace library mechanisms while the front access door is
opened and closed., without interference with most library operations.
slot
A storage location for a cartridge with the library.
TTI
See tape transport interface (TTI) .
tape drive
An electromechanical device that moves magnetic tape and includes mechanisms for
writing and reading data to and from the tape.
