Glossary
G
gigabit interface connector
(GBIC)
A physical component that manages the functions of the FC-0
layer, which is the physical characteristic of the media and
interface, including drivers, transceivers, connectors, and cables.
Mounts on a FC adapter card and connects the VT5900-SA to a
FC host. Also referred to as a Physical Link Module (PLM).
H
hardware path See FC-SCSI Hardware Path ID.
host bus adapter (HBA) See FC Adapter.
HVD High Voltage Differential
I
ID Numerical identifier
indexed addressing A menu name. It allows for generic Fibre Channel host bus
adapters to access SCSI devices attached to the VT5900-SA
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 router in which a Fibre Channel
initiator requests operations to be performed by a SCSI target
device.
IP Internet protocol
L
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.
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 2 km.
