Glossary
Indexed Addressing
It allowsfor generic Fibre Channel host bus adapters to access SCSI
devicesattached to the PSFR-CP41 using a table which is indexed by
sequentialLU N values.
Initiator
A SCSI device(usually a host system) that requests an operation to be
performedby another SCSI device known as the target (forexample, a SCSI
disk or tape drive).
Link
ForFibre Channel, it is a connection between two nodes, each having at
leastone N_Port, interconnected by a pair of optical or copper links, one
inbound and one outbound.
Longwave
Lasers or LEDs that emit lightwith wave lengths around 1300 nm. Long
wavelasers are used for long Fibre Channel links, from ~700 to 2000 m.
Theyare typically used with single-mode fiber of a 9-micron core size.
Loop Address
AFC term indicating the unique ID of a node inFibre Channel loop topology,
sometimesr eferredto as a Loop ID. Also a status type in the FC Status
Menu, showingthe FC Loop Address of the PSFR-CP41.
Loop Port (L_Port)
A FC port that supports loops.
LUN
Logical UnitNumber or Logical Unit; a subdivision of a SCSI target.For
SCSI-3,each SCSI target suppor tsup 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
representssome resource to be managed. A related collection of resources
to be managed.
