Glossary
Fiber optics The branch of optical technology concerned with the transmission of
radiant power through fibers made of transparent materials such as
glass, fused silica, and plastic.
Either a single discrete fiber or a nonspatially aligned fiber bundle
can be used for each information channel. Such fibers are often called
optical fibers to differentiate them from fibers used in
non-communication applications.
Fibre Channel The general name of an integrated set of ANSI standards that define
new protocols for flexible information transfer. Logically, Fibre
Channel is a high-performance serial data channel.
Firmware
The program code (embedded software) that resides and executes on
a connectivity device, such as a Connectrix switch, a Symmetrix Fibre
Channel director, or a host bus adapter (HBA).
Flash Memory A computer chip with a read-only memory that retains its data when
the power is turned off, and that can be erased and reprogrammed
without being removed from the circuit board.
F_Port
Fabric Port, a physical interface within the fabric. An F_Port attaches
to an N_Port through a point-to-point full-duplex link connection.
Frame The smallest indivisible packet of data that is sent on a link.
Frame Header Control information placed before data when encapsulating data for
network transmission.
FRU Field-Replaceable Unit, a hardware component that can be replaced
as an entire unit. The Connectrix switch Product Manager can display
status for the FRUs installed in the unit.
G
Gateway Address In TCP/IP, a device that connects two systems that use the same
or different protocols.
G_Port A physical interface within the fabric capable of acting either as an
F_Port or an E_Port (extension port) depending on the port type at
the other end of the link.
GUI
Graphical user interface.
