Fibre Connection An IBM architecture, technology, and set of products and services
introduced in 1999 and based on the Fibre Channel Standard. FICON
technology uses fiber-optic cables as the data transmission medium,
and significantly improves I/O performance. FICON is the successor
to ESCON, butisdesigned tocoexistwith ESCON technology. See also
Enterprise Systems Connection.
fibre port module
card
A printed circuit board (Intrepid 6064 Director only) that provides
four port connections that support 1.0625 Gbps Fibre Channel
communication. Port connectivity is provided through SFP optical
transceivers. Contrast with universal port module card and 10 Gbps port
module card.
fibre shortest path first A standard Dijkstra’s networking algorithm that calculates to
optimum path between switches in a Fibre Channel fabric. The FSPF
algorithm is applied through the optional open trunking feature.
FICON See Fibre Connection.
FICON management
server
An optional feature that enables inband management and host
control of a director or switch through a server attached to a product
port. The server communicates with the product through a FICON
channel. Contrast with open-systems management server.
field-replaceable unit An assembly removed and replaced in its entirety (on site) when any
assembly components fails.
FLOGI See fabric login.
FL_Port See fabric loop port.
FPM card See fibre port module card.
F_Port See fabric port.
FRU See field-replaceable unit.
FSPF See fibre shortest path first.
full-duplex The capability to simultaneously communicate in both directions
over a single connection, with flow control. Synonymous with
bidirectional, contrast with half-duplex.
