D DLT
Digital Linear Tape technology is owned, developed, and
manufactured by Quantum Corporation. DLT tape drives use half-
inch wide tape. DLT 8000 tape drives record on 208 tracks
(uncompressed).
E Elements
SCSI designation for any device or bin in the library
that can hold a cartridge. SCSI elements include storage bins, tape
drives, load port bins, and the gripper.
EMI
Electro-Magnetic Interference refers to unwanted electrical
noise 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.
ESD
Electro-Static Discharge
G Gripper
A mechanical component of the extension axis assembly
(robotics) which grips and holds a tape cartridge in transit
GUI
An ATL touch screen Graphical User Interface is made up of
bit-mapped graphics displays resembling tabs and buttons,
designed to act as the library’s main console for receiving
information and inputting commands.
HHost
The device or devices to which the library is connected.
HVD
High Voltage Differential or HVD (also called Differential
SCSI). The benefit of using HVD cabling is that it works well in
noisy areas and can reach up to 25 meters in distance. Quantum
DLT8000 and SDLT tape drives can be HVD or LVD devices.
I IEC
The International Electrotechnical Commission is based in
Geneva, Switzerland.
L Load port
The revolving assembly on a front door of ATL
enterprise libraries that incoporates a revolving drum and tape
