Operating Manual
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.
