Dell PowerVault 110T LTO2 (Tape Drive) - Manual (Page 3)

dc. See direct current.
degauss. To make a magnetic tape nonmagnetic by exposing the tape to electrical coils which carry currents that neutralize the magnetism of the tape.
device. Any hardware component or peripheral, such as a tape drive or tape library, that can receive and send data.
device driver. A file that contains the firmware that is needed to use an attached device.
diagnostic. A software program that is designed to recognize, locate, and explain faults in equipment or errors in programs.
direct current (dc). An electric current flowing in one direction only and substantially constant in value.
drive. A data-storage device that controls the movement of the magnetic tape in a tape cartridge. The drive houses the mechanism (drive head) that reads and writes data to
the tape.
drive dump. The recording, at a particular instant, of the contents of all or part of one storage device into another storage device, usually as a safeguard against faults or
errors, or in connection with debugging.
drive head. The component that records an electrical signal onto magnetic tape, or reads a signal from tape into an electrical signal.
drive sense data. See SCSI drive sense data.
dump. See drive dump.
E
eject. To remove or force out from within.
enclosure. A device, such as a desktop unit, tape cartridge autoloader, or tape library, into which you can install the tape drive.
error log. Maintained by the tape drive, a list that contains the ten most recent error codes. The codes identify errors that pertain to the drive.
F
file. A named set of records that are stored or processed as a unit.
firmware. The proprietary code that is usually delivered as part of an operating system. Firmware is more efficient than software that is loaded from an alterable medium, and
is more adaptable to change than pure hardware circuitry. An example of firmware is the Basic Input/Output System (BIOS) in read-only memory (ROM) on a PC
motherboard.
G
GB. See gigabyte.
Generation 1. The informal name for the Ultrium tape drive, which is the predecessor of the tape drive (Generation 2). The Generation 1 drive has a native storage capacity of
up to 100 GB per cartridge and a native sustained data transfer rate of 15 MB per second.
Generation 2. The informal name for the Ultrium 2 Tape Drive, which is the second-generation version of the Ultrium tape drive (Generation 1). The Generation 2 drive has a
native storage capacity of up to 200 GB per cartridge and a native sustained data transfer rate of 35 MB per second.
gigabyte. 1 000 000 000 bytes.
ground. An object that makes an electrical connection with the earth.
H
hardware. The physical equipment or devices that form a computer.
head. See drive head.
Head Resistance Measurements test. Part of the Test Head diagnostic, a procedure that determines whether the tape drive's head works correctly. The test measures the
head's ability to withstand cracks and other defects.
host. The controlling or highest-level system in a data communication configuration. Synonymous with server.
I
ID. Identifier.
in. See inch.
