Generation 3
The informal name for the
third-generation version of the IBM
Ultrium Tape Drive. The Generation 3
drive has a native storage capacity of up
to 400 GB per cartridge and a native
sustained data transfer rate of 135 MB per
second.
Generation 4
The informal name for the
fourth-generation version of the IBM
Ultrium Tape Drive. The Generation 4
drive has a native storage capacity of up
to 800 GB per cartridge and a native
sustained data transfer rate of 135 MB per
second.
Generation 5
The informal name for the fifth-generation
version of the IBM Ultrium Tape Drive.
The Generation 5 drive has a native
storage capacity of up to 1500 GB per
cartridge and a native sustained data
transfer rate of 140 MB per second.
Generation 6
The informal name for the
sixth-generation version of the IBM
Ultrium Tape Drive. The Generation 6
drive has a native storage capacity of up
to 2500 GB per cartridge and a native
sustained data transfer rate of 160 MB per
second.
Generation 7
The informal name for the
seventh-generation version of the IBM
Ultrium Tape Drive. The Generation 7
drive has a native storage capacity of up
to 6000 GB per cartridge and a native
sustained data transfer rate of 300 MB per
second.
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.
