exchange The highest level Fibre Channel mechanism used for communication between
N_Ports. Composed of one or more related sequences, and can work in either one
or both directions.
F_Port Fabric port. A port that is able to transmit under fabric protocol and interface over
links. Can be used to connect an N_Port to a switch.
fabric A Fibre Channel network containing two or more switches in addition to hosts and
devices. May also be referred to as a switched fabric.
fabric name The unique identifier assigned to a fabric and communicated during login and port
discovery.
FCIA Fibre Channel Industry Association. An international organization of Fibre Channel
industry professionals. Among other things, provides oversight of ANSI and industry
developed standards.
FCP Fibre Channel Protocol. Mapping of protocols onto the Fibre Channel standard
protocols. For example, SCSI FCP maps SCSI-3 onto Fibre Channel.
FCS switch Fabric Configuration Server Switch. One or more designated HP switches that store
and manage the configuration and security parameters for all switches in the fabric.
FCS switches are designated by WWN, and the list of designated switches is
communicated fabric-wide.
fill word An IDLE or ARB ordered set that is transmitted during breaks between data frames
to keep the Fibre Channel link active.
FL_Port Fabric loop port. A port that is able to transmit under fabric protocol and also has
arbitrated loop capabilities. Can be used to connect an NL_Port to a switch.
FRU Field-Replaceable Unit. A component that can be replaced on site.
FS Fibre Channel Service. A service that is defined by Fibre Channel standards and
exists at a well-known address. For example, the Simple Name Server is a Fibre
Channel service.
FSP Fibre Channel service protocol. The common protocol for all fabric services,
transparent to the fabric type or topology.
FSPF Fabric shortest path first. HP's routing protocol for Fibre Channel switches.
Fx_Port A fabric port that can operate as either an F_Port or FL_Port.
G_Port Generic port. A port that can operate as either an E_Port or F_Port. A port is
defined as a G_Port when it is not yet connected or has not yet assumed a specific
function in the fabric.
