place, by means of a robotic device, a tape
cartridge into a storage slot, drive, or I/O
station.
Q
quiesce
To put a device into a temporarily
inactive or inhibited state, but not remove
it from the system.
R
RABF See recursive accumulating backhitchless
flush.
radio frequency identification labels
An adhesive bar code label with an
embedded radio frequency identification
tag that can be used to track tape
cartridges.
rail system
Within the TS3500 Tape Library, the
support structure over which the
cartridge accessor moves.
read To acquire or interpret data from a
storage device, from a data medium, or
from another source.
ready The operating condition that the TS3500
Tape Library is in when the host
applications can interact with it.
recursive accumulating backhitchless flush
(RABF)
A non-volatile caching technique used by
the 3592 tape drives.
rekey In cryptography, the process of encrypting
a data key a second time by using the
public key of another party to create an
additional externally encrypted data key.
The cartridge can then be shipped to a
business partner that holds the
corresponding private key which allows
the data key to be unwrapped and the
tape decrypted on a different TS1120 Tape
Drive or TS1130 Tape Drive.
relative humidity
The ratio of the amount of water vapor
actually present in the air to the greatest
amount possible at the same temperature.
remote support
See Call Home.
Remote Technical Assistance Information
Network (RETAIN
®
)
Used by IBM Service Representatives, an
internal host-based software application
that contains records of service problems
with IBM hardware and software, as well
as tips on how to deal with the problems.
remove
Pertaining to the TS3500 Tape Library, a
term used to describe the act of taking a
tape cartridge out of an I/O station.
repeater
A device that regenerates signals to
extend the range of transmission between
data stations or to interconnect two
branches. A repeater is a node of a local
area network.
RETAIN
See Remote Technical Assistance Information
Network.
RFID See radio frequency identification labels.
robotics
The cartridge accessor and any associated
mechanisms that move a tape cartridge
within the TS3500 Tape Library.
RS-422 interface
An electrical interface standard approved
by the Electronic Industries Association
(EIA) for connecting serial devices. The
RS-422 standard, which supports higher
data rates and greater immunity to
electrical interference, is an alternative to
the older RS-232 interface and uses
individual differential signal pairs for
data transmission. Depending on data
transmission rates, RS-422 can be used at
distances to 1,275 m (4,000 ft). The RS-422
interface also supports multi-point
connections.

SAN See Storage Area Network.
SARS See Statistical Analysis and Reporting
System.
SC1 Model SC1. See Shuttle connection.
scratch cartridge
A labeled cartridge that is blank or
contains no valid data, that is not
currently defined, and that is available for
use.
