E
ESD
Electro-Static Discharge
G
Robot
A mechanical component of the extension axis assembly
(robotics) which grips and holds a tape cartridge in transit
H
Host
The device or devices to which the library is connected.
I
In-Line
A process (like de-duplication) is running while the data is
ingested.
IEC
The International Electrotechnical Commission is based in
Geneva, Switzerland.
L
LTO
Linear Tape-Open (LTO) technology was developed jointly by
HP, IBM and Quantum to provide a clear and viable choice in an
increasingly complex array of tape storage options.
LTO technology is an "open format" technology, which means
that users will have multiple sources of product and media. The
"open" nature of LTO technology also provides a means of
enabling compatibility between different vendors' offerings.
The Ultrium format is the "high capacity" implementation of LTO
technology.
M
MSBF
Mean Swaps Before Failure
MTBF
Mean Time Between Failures
MTTR
Mean Time To Repair
N
Namespace
A namespace file contains all of the deduplicated tags for a
replication set
Nearline
Nealine indicates a secondary process and not running as data
is received.
NEMA
National Electrical Manufacturers Association
P
PCI
The PCI bus typically runs at speeds of 33 MHz or 66 MHz and is
usually 32 bits wide. This means that it passes 32 bits of data
simultaneously as if down 32 separate wires. Some of the most
recent computers include "wider" 64-bit PCI buses, and already
