Model L23 - IBM TotalStorage Ultrium 3580 L23 Setup And Operator Manual

system that enables data communication between a
supported server and another device, such as the 3580
Ultrium 2 Tape Drive. LVD signaling uses two wires to
drive one signal over copper wire. The use of wire
pairs reduces electrical noise and crosstalk.
LTO. Linear Tape-Open.
LTO-CM. LTO cartridge memory.
LTO cartridge memory (LTO-CM). Within each IBM
LTO Ultrium Data Cartridge, an embedded electronics
and interface module that can store and retrieve a
cartridge's historical usage and other information.
LVD. Low voltage differential.
M
m. Meter.
magnetic tape. A tape with a magnetizable surface
layer on which data can be stored by magnetic
recording.
maintenance mode. The state of operation in which
the 3580 Ultrium 2 Tape Drive must be before it can
run tape drive diagnostics or maintenance procedures.
MB. Megabyte.
MBps. Megabytes per second.
media. The plural of medium.
media capacity. See capacity.
medium. A physical material (such as magnetic tape)
in or on which data may be represented.
megabyte (MB). 1 000 000 bytes.
message display. Located on the front of the 3580
Ultrium 2 Tape Drive, an LCD display that provides
information about the status of the tape drive and any
error conditions.
metal particle tape. In the LTO Ultrium Tape
Cartridge, tape that uses very small, pure metal
particles (rather than oxide coatings) in the magnetic
layer.
meter. In the Metric System, the basic unit of length;
equal to approximately 39.37 inches.
Model L23. One of two versions of the 3580 Ultrium 2
Tape Drive. The Model L23 uses the Ultra2, Low
Voltage Differential (LVD) SCSI interface. Contrast with
Model H23.
Model H23. One of two versions of the 3580 Ultrium
2 Tape Drive. The Model H23 uses the Ultra, High
Voltage Differential (HVD) SCSI interface. Contrast
with Model L23.

N
native data capacity. The amount of data that can be
stored without compression on a tape cartridge.
O
oersted. The unit of magnetic field strength in the
unrationalized centimeter-gram-second (cgs)
electromagnetic system. The oersted is the magnetic
field strength in the interior of an elongated, uniformly
wound solenoid that is excited with a linear current
density in its winding of one abamper per 4
centimeters of axial length.
operating environment. The temperature, relative
humidity rate, and wet bulb temperature of the room
in which the 3580 Ultrium 2 Tape Drive routinely
conducts processing.
operating system. The master computer control
program that translates the user's commands and
allows software application programs to interact with
the computer's hardware.
P
PDF. Portable Document Format.
Portable Document Format (PDF). A standard
specified by Adobe Systems, Incorporated, for the
electronic distribution of documents. PDF files are
compact, can be distributed globally (by e-mail, the
web, intranets, or CD-ROM), and can be viewed with
the Acrobat Reader, which is software from Adobe
Systems that can be downloaded at no cost from the
Adobe Systems home page.
POST. Power-On Self Test.
PostScript. A standard specified by Adobe Systems,
Incorporated, that defines how text and graphics are
presented on printers and display devices.
pot-setting tool. Normally used on a potentiometer to
adjust resistance, a tool that slides over the shaft of the
loader motor gear in the 3580 Ultrium 2 Tape Drive
and holds the shaft for easy turning.
power cord. A cable that connects a device to a source
of electrical power.
power-off. To remove electrical power from a device.
power-on. To apply electrical power to a device.
Power-On Self Test (POST). A series of diagnostic
tests that are run automatically by a device when the
power to that device is turned on.
