iSR6200 Intelligent Storage Router
Installation Guide
failover path
Software feature that ensures data avail-
ability and system reliability by assigning
alternate path and automatic adapter
failover for device resources. This feature
is available only in Windows
2000/Windows Server 2003/Windows
Vista, Novell NetWare, and Red Hat/SUSE
Linux. (Windows XP and Windows Server
2008 do not support failover.)
FC
See Fibre Channel.
FC-IP mode
Data transportation mode in which the
iSR6200 transports Fibre Channel frames
over a TCP/IP connection using the FCIP
(Fibre Channel over IP) protocol to
connect two iSR6200 routers. In FC-IP
mode, a port pair (one Fibre Channel port
and an IP port on the same router) on local
iSR6200 and another port pair on a remote
router form a FCIP route.
FCIP (Fibre Channel over IP)
Protocol that enables transmission of Fibre
Channel information by tunneling data on
a SAN over IP networks. An alternative to
iSCSI. Also known as Fibre Channel
tunneling.
FCoE
Fibre Channel over Ethernet. A new
technology defined by the T11 standards
body that allows traditional Fibre Channel
storage networking traffic to travel over an
Ethernet link by encapsulating Fibre
Channel frames inside Layer 2 Ethernet
frames. For more information, visit

.
Fibre Channel
A high-speed serial interface technology
that supports other higher layer protocols
such as SCSI and IP.
FL_Port
Fabric loop port. In a Fibre Channel, the
fabric switch is capable of Fibre Channel
arbitrated loop operations and is
connected to one or more NL_Ports by a
Fibre Channel Arbitrated Loop. An
FL_Port becomes a shared entry point for
public NL_Port devices to a Fibre Channel
fabric. FL_Ports are intermediate ports in
virtual point-to-point links between end
ports that do not reside on the same loop,
for example NL_Port to FL_Port to F_Port
to N_Port through a single Fibre Channel
fabric switch.
Flash
Non-volatile memory where the boot code
is saved. At times, Flash and boot code
are used interchangeably.
Flash BIOS
A QLA2xxx adapter's flash programmable
read-only memory (PROM) contains the
code that allows booting from the adapter
at startup.
frame
Data unit consisting of a start-of-frame
(SOF) delimiter, header, data payload,
CRC, and an end-of-frame (EOF) delim-
iter.
FRU
Field replaceable unit. Component that
can be replaced in the field upon failure.
