iSR6152 Intelligent Storage Router
Installation Guide
FC-IP mode
Data transportation mode in which the
iSR6152 transports Fibre Channel frames
over a TCP/IP connection using the FCIP
protocol to connect two iSR6152 routers.
In FC-IP mode, a port pair (one Fibre
Channel port and an IP port on the same
router) on local iSR6152 and another port
pair on a remote router form an FCIP
route.
FCIP
Fibre Channel over IP. Protocol that
enables transmission of Fibre Channel
information by tunneling data on a SAN
over IP networks.
FCP
Fibre Channel protocol. SCSI to Fibre
Channel mapping.
Fibre Channel
A high-speed serial interface technology
that supports other higher layer protocols
such as SCSI and IP.
Fibre Channel over IP
See FCIP.
field replaceable unit
See FRU.
FL_Port
Fabric loop port. In 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.
G_Port
Generic port. A port that can operate as
either an E_Port or an F_Port. A G_Port
can determine operating mode at switch
port initialization, F_Port when an N_Port
attachment is determined, E_Port when an
E_Port attachment is determined. See
E_Port, F_Port, FL_Port, L_Port, N_Port,
NL_Port.
