What is an F-port?

September 9, 2022 Chris Normand

The fabric port (F_port) is a fabric switch port used to connect an N_port to a switch in a fiber channel topology. It uses a fiber channel point-to-point (FC-P2P) topology – a structure connecting two fiber channel devices.

What is F-port in switch?

F-port. Fabric Port Switches. Switch. port used to connect the Fibre Channel fabric to a node.

What are N ports?

Form N-PORT is the reporting form that is to be used for monthly reports of Funds other than money market funds and SBICs under section 30(b) of the Act, as required by rule 30b1-9 under the Act (17 CFR 270.30b1-9).

What is a G port?

A generic port (G_Port) is a port that supports either an E_Port or F_Port in a fiber channel (FC) switch topology. It can be found on Brocade and McData switches. The fiber channel was developed in 1988 and approved by the American National Standards Institute (ANSI) in 1994.

What is a port in SAN?

In SAN environment, every port has to go through initialization process. During that process every port is categorized under specific type. Depends if the port is a device port – it can become N_Port or NL_Port. If it's a switch port – it usually becomes either U_Port, F_Port or E_Port.

What is N port in Fibre Channel?

N_Port—An N_Port is a port on the node of an FC device such as a server or a storage device and is also known as a node port. F_Port—An F_Port is a port on an FC switch that connects to an FC device N_Port in a point-to-point connection. F_Ports are also known as fabric ports.

What protocol does fiber use?

Fibre Channel over TCP/IP (FCIP), defined in IETF RFC 3821, is a pure Fibre Channel encapsulation protocol. It allows the interconnection of islands of Fibre Channel storage area networks through IP-based networks to form a unified storage area network.

What is G port in switch?

Answer. A G-port is one that has negotiated as a generic or universal port. A G-port can be used as either an F-port or E-port but will need to be locked to that mode per documentation for that brand of switch.

What is F port?

The fabric port (F_port) is a fabric switch port used to connect an N_port to a switch in a fiber channel topology. It uses a fiber channel point-to-point (FC-P2P) topology – a structure connecting two fiber channel devices.

What is Fibre Channel used for?

Fibre Channel is a high-speed networking technology primarily used for transmitting data among data centers, computer servers, switches and storage at data rates of up to 128 Gbps.

What is an F port?

What Does Fabric Port (F_Port) Mean? The fabric port (F_port) is a fabric switch port used to connect an N_port to a switch in a fiber channel topology. It uses a fiber channel point-to-point (FC-P2P) topology – a structure connecting two fiber channel devices.

How fast is fiber channel?

Fibre channel supports a transmission speed of 1, 2, 4, 8, 16, 32, and 128 Gbps. While, the speed of optical transceiver used in Ethernet ranges from Fast Ethernet of up to 100 Mbps, Gigabit Ethernet of up to 1000Mbps, 10 Gigabit of up to 10 Gbps to even some 40 or 100 Gbps today.

What is a storage device port directly attached to a fabric called?

Device Ports

N_Port – Node Port – a Fabric device directly attached. Such device can be either an initiator or a target. In storage world targets are storage arrays, and initiators are hosts/servers.

What is a Fibre Channel controller?

A Fibre Channel (FC) adapter is a hardware component that provides connectivity from a server to a storage area network (SAN). An FC adapter, which uses the Peripheral Component Interconnect (PCI) slots on the server, can have one, two or four ports.

What is FC in computer?

A fiber channel (FC) is a computer networking technology that is used to transfer data between one or more computers at very high speeds.

What is a fiber port?

An SFP port is a slot on a network device or computer into which small form-factor pluggable (SFP) transceivers are inserted. An SFP transceiver, also known as an SFP module, is just a hot-swappable, pinky-sized metal component that, when connected to another device using a cable, allows for the transmission of data.

What is G port?

A G-port is one that has negotiated as a generic or universal port. A G-port can be used as either an F-port or E-port but will need to be locked to that mode per documentation for that brand of switch.

What is IP SAN storage?

An IP SAN is a Storage Area Network that uses the iSCSI protocol to transfer block-level data over a network, generally Ethernet. Initiator. In this document the term “initiator” is used interchangeably to refer to a server, host or device driver that initiates (i.e. begins) iSCSI command sequences.

What is Ethernet fiber switch?

Ethernet switch, the most common form of network switch, is a computer networking device used in Ethernet to connect various Ethernet devices. It connects devices together by using packet switching to receive, process, and forward data from one source device to another destination device.

What is the difference between Fibre Channel and Ethernet?

The differences between Fibre Channel- and Ethernet-based storage are significant. Whilst Fibre Channel is a specific storage protocol, Ethernet is a LAN protocol. Ethernet has undergone many changes since its inception, and combined with TCP/IP can be utilized successfully for NAS.

What is an F-port?

What Does Fabric Port (F_Port) Mean? The fabric port (F_port) is a fabric switch port used to connect an N_port to a switch in a fiber channel topology. It uses a fiber channel point-to-point (FC-P2P) topology – a structure connecting two fiber channel devices.
