ID Numerical identifier

indexed addressing A menu name. It allows for generic Fibre Channel host bus adapters to access

SCSI devices attached to the 4x50 using a table which is indexed by sequential

LUN values.

initiator A device (usually a host system) that requests an operation to be performed by

another device known as a target (usually a peripheral).

initiator mode Configuration mode of the storage router in which a Fibre Channel initiator

requests operations to be performed by a SCSI target device.

IP Internet Protocol

Link For Fibre Channel, it is a connection between two nodes, each having at least

one N_Port (or the other end could be an F-Port), interconnected by a pair of

optical or copper links, one inbound and one outbound.

Local Area Network

(LAN)

A communications system with dimensions that are typically less than

5 kilometers. Transmissions within a local area network are mostly digital,

carrying data among stations at rates usually above one megabit/sec.

longwave Lasers or LEDs that emit light with wave lengths around 1300 nm. When using

single mode (9 nm) fibre, longwave lasers can be used to achieve lengths

greater than 2Km.

loop address A FC term indicating the unique ID of a node in Fibre Channel loop topology,

sometimes referred to as a Loop ID. Also a status type in the FC Status menu,

showing the FC Loop Address of the 4x50.

Loop Port (L_Port) A FC port that supports loops.

LUN Logical Unit Number or Logical Unit; a subdivision of a SCSI target. For SCSI-

3, each SCSI target supports up to sixteen LUNs (LUN-0 to LUN-16). Using

LUNs, the FC host can address multiple peripheral devices that may share a

common controller.
