FC_SB Fibre Channel single bytes.
FC_VI Fibre Channel virtual interface.
FCA Flow-control acknowledgement (DLSW).
FCIA Fibre Channel Industry Association. An international organization of Fibre Channel industry
professionals. Provides oversight of ANSI and industry-developed standards, among other tasks.
FCIP
Tunneling
Service
The Brocade Multiprotocol SAN Routing Service that enables SANs to span longer distances than
could be supported with native Fibre Channel links. FCIP is a TCP/IP-based tunneling protocol that
allows the transparent interconnection of geographically distributed SAN islands through an IP-based
network.
FCLC Fibre Channel Loop Community.
FCP Fibre Channel Protocol. Mapping of protocols onto the Fibre Channel standard protocols. For example,
SCSI FCP maps SCSI-3 onto Fibre Channel.
FCRP Fibre Channel Router Protocol. A Brocade-authored protocol that enables LSAN switches to perform
routing between different edge fabrics, optionally across a backbone fabric.
FCRS Fibre Channel Routing Service. The Brocade Multiprotocol SAN Routing Service that extends
hierarchical networking capabilities to Fibre Channel fabrics. Sometimes called “FC-to-FC routing,”
FCRS enables devices located on separate fabrics to communicate without merging the fabrics. It also
enables the creation of LSANs.
FCS Fibre Channel switch; alternatively, Fabric Configuration Server.
FCS switch Relates to the Brocade Secure Fabric OS feature. One or more designated switches that store and
manage security parameters and configuration data for all switches in the fabric. They also act as a set
of backup switches to the primary FCS switch. See also backbone fabric, primary FCS switch.
FC-SW-2 The second-generation Fibre Channel Switch Fabric standard defined by ANSI. Specifies tools and
algorithms for the interconnection and initialization of Fibre Channel switches to create a multiswitch
Fibre Channel fabric.
FDDI Fibre Distributed Data Interface. An ANSI architecture for a metropolitan area network (MAN); a
network based on the use of fiber-optic cable to transmit data at 100 Mbit/sec.
FDMI Fabric-Device Management Interface. FDMI is a database service provided by the fabric for Nx_Ports.
The primary use is by HBA devices that register information about themselves and their ports.
FFFFF5 Well-known Fibre Channel address for a Class 6 multicast server.
FFFFF6 Well-known Fibre Channel address for a clock synchronization server.
FFFFF7 Well-known Fibre Channel address for a security key distribution server.
FFFFF8 Well-known Fibre Channel address for an alias server.
FFFFF9 Well-known Fibre Channel address for a QoS facilitator.
