FC Port
An opening at the back of the PowerVault 35F that provides a fiber optic connection between the FC
adapter and the FC host.
FC-SCSI Hardware Path ID
A FC term describing a list of values showing the physical hardware path of the FC host to the target
device.
Format: Bus_Converter/Adapter_Address.Protocol_Type.Area.Port.Bus.Target.LUN
Example: 8/4.8.0.0.2.4.0
Fiber
The fiber optic cable made from thin strands of glass through which data in the form of light pulses is
transmitted (LASER, LED). It is used for high-speed transmission over medium (200m) to long
(10km)distances.
Fibre
A generic FC term used to cover all transmission media types specified in the Fibre Channel Physical
Layer standard (FC-PH), such as optical fiber, copper twisted pair, and copper coaxial cable.
Fibre Channel (FC)
Logically, the Fibre Channel is a bidirectional, full-duplex, point-to-point, serial data channel structured
for high performance data communication. Physically, the Fibre Channel is an interconnection of multiple
communication ports, called N_Ports, interconnected by a switching network, called a fabric, a point-to-
point link, or an arbitrated loop. Fibre Channel is a generalized transport mechanism that has no protocol
of its own or native input/output command set, but can transport any existing Upper Level Protocols
(ULPs) such as SCSI and IP.
Fibre Channel - Arbitrated Loop (FC-AL)
One of three existing Fibre Channel topologies, in which 2 to 126 devices are interconnected serially in a
single loop circuit. The arbitrated loop topology supports all classes of service and guarantees in order
delivery of frames when the source and destination are on the same loop.
Fibre Channel Protocol for SCSI (FCP)
FCP defines a Fibre Channel mapping layer (FC-4) that uses FC-PH services to transmit SCSI command,
data, and status information between a SCSI initiator and a SCSI target. Using FCP enables transmission
and receipt of SCSI commands, data and status, across the Fibre Channel using the standard Fibre Channel
frame and sequence formats.
Frame
The smallest, indivisible unit of information transfer used by Fibre Channel. Frames are used for
transferring data associated with a sequence. Frame size depends on the hardware implementation and is
independent of the ULP or the application software.
Gigabaud Interface Converter (GBIC)
A physical component that manages the functions of the FC-0 layer, which is the physical characteristic of
