Glossary
A one-byte value used to identify a port in an Arbitrated Loop topology.
The value of the AL_PA corresponds to bits 7:0 of the 24-bit Native
Address Identifier.
The process of selecting one respondent from a group requesting
service at the same time.
An Arbitrated Loop protocol used to terminate a loop circuit.
The fill word that the Loop Port State Machine uses when a fill word is to
be transmitted.
Two fibers in one cable suitable for duplex transmission.
Light transmission through optical fibers for communication or signaling
Fibre Channel is a data transfer interface technology that maps several
common transport protocols including IP and SCSI, allowing it to merge
high-speed I/O and networking functionality in a single connectivity
technology. Fibre channel is an open standard as defined by ANSI and
OSI standards and operates over copper and fiber optic cabling at
distances of up to 10 Kilometers. It is unique in its support of multiple
interoperable topologies including point-to-point, arbitrated-loop and
switching and it offers several qualities of service for network
optimization. With its large packet sizes, Fibre Channel is ideal for
storage, video, graphic and mass data transfer applications.
Light-Emitting Diode. A status indicator on a switch.
Gigabits per second.
An entity with one or more N_Ports or NL_Ports.
An Arbitrated Loop protocol used to establish a loop circuit.
A data transmission convention which may include timing, control,
formatting, error detection with correction and data representation.
Small Computer System Interface. Standard interface for storage
modules.
Small Form-Factor Pluggable transceiver. These transceivers are fully
compliant with FC-PI and MSA standards and occupy less than half the
board space of the existing GBIC products.
The logical and/or physical arrangement of stations on a network. Fibre
Channel topologies include point-to-point, Arbitrated Loop, and switched
fabric.
A device that converts one form of signaling to another for both
transmission and reception. SFPs and GBICs are transceivers.
