Digital Linear Tape technology is owned, developed, and
DLT
manufactured by Quantum Corporation. DLT tape drives use half-inch
wide tape. DLT 8000 tape drives record on 208 tracks (uncompressed).
SCSI designation for any device or bin in the library that can
Elements
hold a cartridge. SCSI elements include storage bins, tape drives, load
port bins, and the gripper.
Electro-Magnetic Interference refers to unwanted electrical noise
EMI
present on a power line. This noise may "leak" from the power lines and
affect equipment that isn't even connected to the power line. Such
"leakage" is called a magnetic field. Magnetic fields are formed when
unwanted noise voltages give rise to noise currents. Such noise signals
may adversely affect electronic equipment and cause intermittent data
problems.
Electrostatic Discharge
ESD
A mechanical component of the extension axis assembly
Gripper
(robotics) which grips and holds a tape cartridge in transit
An touch screen Graphical User Interface is made up of bit-mapped
GUI
graphics displays resembling tabs and buttons, designed to act as the
library's main console for receiving information and inputting
commands.
The device or devices to which the library is connected.
Host
High Voltage Differential or HVD (also called Differential SCSI).
HVD
The benefit of using HVD cabling is that it works well in noisy areas and
can reach up to 25 meters in distance. Quantum DLT 8000, SDLT 220, and
SDLT 320 tape drives can be HVD or LVD devices.
The International Electrotechnical Commission is based in Geneva,
IEC
Switzerland.
The revolving assembly on a front door of enterprise libraries
Load port
that incorporates a revolving drum and tape cartridge bins (stationary or
removable) for loading and unloading tape cartridges.
Linear Tape-Open is a tape drive specification backed by IBM,
LTO
Hewlett-Packard, and Certance.
