Dimensions of a drive that meet standard height
full height
requirements, usually 3.25 inches (82.55 mm) for a tape or disk drive
product.
Gigabyte. A unit of measurement equal to 1 million kilobytes.
GB
Gigahertz. A measurement of frequency that equals one thousand
GHz
million Hz, or one thousand MHz. Speeds for computer microprocessors,
buses, and interfaces are often measured in GHz.
Standard drive size equivalent to half the vertical space of a
half height
5.25 inch (133.35 mm) drive.
A drive that reads and writes data on a hard disk. The terms
hard drive
hard drive and hard disk are often used interchangeably.
A data error that persists when the tape is reread, usually
hard error
caused by defects in the physical surface.
The tiny electromagnetic coil and metal pole used to create and
head
read back the magnetic patters on the tape. Also known as the read/write
head.
The length of time a tape drive head will function without
head life
replacement or repair, usually measured in hours of use.
Hierarchical Storage Management (HSM)
amounts of data in tape libraries that allows for easy and rapid recall of
the material. Due to the lowering cost of disk drives, HSM has yet to
reach its full potential.
Hypertext Transfer Protocol. A protocol for exchanging files
HTTP
between computers connected to the Internet.
Hertz. A unit of frequency measurement that equals 1 cycle per
Hz
second. Computers and electronic devices are often measured in
kilohertz (kHz), megahertz (MHz), gigahertz (GHz), or terahertz (THz).
Independent Software Vendor.
ISV
A backup option that takes a "snapshot" of an entire
image backup
system by writing a volume image to tape sector-by-sector, rather than
file-by-file. This method of backup is very fast and allows companies to
backup critical information in a limited backup window.
A hardware or software protocol, contained in the electronics
interface
of the tape controller and tape drive that managed the exchange of data
