Glossary

Indexed Addressing

It allows for generic Fibre Channel host bus adapters to access SCSI devices attached to the PSFR-CP41 using a table which is indexed by sequential LUN values.

Initiator

A SCSI device (usually a host system) that requests an operation to be performed by another SCSI device known as the target (for example, a SCSI disk or tape drive).

Link

For Fibre Channel, it is a connection between two nodes, each having at least one N_Port, interconnected by a pair of optical or copper links, one inbound and one outbound.

Longwave

Lasers or LEDs that emit light with wave lengths around 1300 nm. Long wave lasers are used for long Fibre Channel links, from ~700 to 2000 m. They are typically used with single-mode fiber of a 9-micron core size.

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 PSFR-CP41.

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.

Management Information Base (MIB)

A structured set of data variables, called objects, in which each variable represents some resource to be managed. A related collection of resources to be managed.
