moderate-sized geographic area (1 to 10 km) such as a single office building, warehouse, or campus.

log sense data. See SCSI log sense data.

loop. (1) A series of instructions that is repeated until a terminating condition is reached. (2) To connect so as to complete a loop.

loop ID. See loop identifier.

loop identifier (LID). In a Fibre Channel topology, the identifier that a device assigns to an Ultrium 2 Tape Drive. An operator uses the LID to set the AL_PA.

loop identifier (LID)/status connector. Located on the Model T400F, the connector that is used to set the Loop ID and provide status about the loop.

loop initialization protocol (LIP). A method by which a device in a Fibre Channel Arbitrated Loop acquires its AL_PA.

loss. In fiber optics technology, the amount of a signal’s power (expressed in dB) that is lost in connectors, splices, or fiber defects.

Low Voltage Differential (LVD). A low-noise,low-power, and low-amplitude electrical signaling system that enables data communication between a supported server and the 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.

L_port. Located on the Ultrium 2 Tape Drive, the Fibre Channel portal that facilitates communication only in an FC-AL topology. An L_port also allows connection to FL_ports and NL_ports.

LTO. See Linear Tape-Open.

LTO cartridge memory (LTO-CM). Within each LTO Ultrium Data Cartridge, an embedded electronics and interface module that can store and retrieve a cartridge’s historical usage and other information.

LTO-CM.See LTO cartridge memory.

LTO-DC.See LTO Data Compression.

LTO Data Compression (LTO-DC). A method that compresses a server’s data before the drive writes it to tape. LTO-DC detects but does not recompress or test record boundaries and file markers (which are encoded as control symbols). It also allows switching between compression and no compression within the data stream, which prevents data from expanding when the drive compresses random or encrypted data.

LVD. See Low Voltage Differential.

M

m.See 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 Ultrium 2 Tape Drive must be before it can run diagnostics, verify write and read operations, verify a suspect tape cartridge, update its own firmware, and perform other diagnostic and maintenance functions.

MB. See megabyte.

media. The plural of medium.

media capacity. See capacity.

medium. A physical material in or on which data may be represented, such as magnetic tape.

megabyte (MB). 1 000 000 bytes.

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.

micrometer. One millionth of a meter (.000001 m). Synonymous with micron. Abbreviated as µm.

micron. One millionth of a meter (.000001 m). Synonymous with micrometer. Abbreviated as µm.

microsecond. One millionth of a second (.000001 s). Abbreviated as µs.

millimeter (mm). One thousandth of a meter (.001 m).

millisecond (ms). One thousandth of a second (.001 s).

mm.See millimeter.

Model T400. The version of the IBM TotalStorage LTO Ultrium 2 Tape Drive that uses the SCSI interface.

Model T400F. The version of the IBM TotalStorage LTO Ultrium 2 Tape Drive that uses the Fibre Channel interface.

ms. See millisecond.

multimode fiber. An optical fiber that has a core that is large enough to propagate more than one electromagnetic wave of light. The typical diameter is 62.5 micrometers.
