gigabit (Gbit)
1 000 000 000 bits.
gigabyte (GB)
1 000 000 000 bytes.
Gigabit Interface Converter (GBIC)
Converts copper interface to optic interface.
gnd
Ground.
H
hertz (Hz)
Unit of frequency. One hertz equals one cycle per second.
hex
Hexadecimal.
High Voltage Differential (HVD)
A logic-signaling system that enables data communication between a supported host and the library. HVD signaling uses a paired plus and minus signal level
to reduce the effects of noise on the SCSI bus. Any noise that is injected into the signal is present in both a plus and minus state, and is canceled.
Synonymous with differential.
HVD
SCSI Bus High Voltage Differential
Hz
Hertz (cycles per second).
I
IBM Spectrum Archive
Formerly known as Linear Tape File System (LTFS). A file system that works with LTO Generation tape technology to access data stored on an IBM tape
cartridge.
IBM Ultrium Tape Drive
Located within the library, a data-storage device that controls the movement of the magnetic tape in an IBM LTO Ultrium Tape Cartridge. The drive houses
the mechanism (drive head) that reads and writes data to the tape.
ID
Identifier.
identifier (ID)
(1) In programming languages, a lexical unit that names a language object; for example, the names of variables, arrays, records, labels, or procedures. An
identifier usually consists of a letter optionally followed by letters, digits, or other characters. (2) One or more characters that are used to identify or name
data element and possibly to indicate certain properties of that data element. (3) A sequence of bits or characters that identifies a program, device, or
system to another program, device, or system.
IML
Initial microprogram load.
initial microprogram load (IML)
The action of loading a microprogram from an external storage to writable control storage.
