frame

The Fibre Channel structure that transmits data between ports. Consists of a start-of-frame delimiter, header, optional

headers, data payload, cyclic redundancy check (CRC), and end-of-frame delimiter. There are two types of frames:

link control frames (transmission acknowledgements and so forth) and data frames.

FRU

Field-replaceable unit. A component that can be replaced onsite.

FSPF

Fabric shortest path first. The standard routing protocol for Fibre Channel switches.

FSS

Fabric OS state synchronization. The FSS service is related to HA. The primary function of FSS is to deliver state

update messages from active components to their peer standby components. FSS determines whether fabric elements

are synchronized (and thus FSS compliant).

FTP

File Transfer Protocol.

full fabric

The HP software license that allows multiple E_Ports on a switch, making it possible to create multiple ISL links.

full fabric citizenship

A loop device that has an entry in the Simple Name Server.

full-duplex

A mode of communication that allows the same port to simultaneously transmit and receive frames. See also

Fx_Port

A fabric port that can operate as either an F_Port or FL_Port. See also

G_Port

Generic port. A port that can operate as either an E_Port or an F_Port. A port is defined as a G_Port when it is not

yet connected or has not yet assumed a specific function in the fabric.

gateway

Hardware that connects incompatible networks by providing translation for both hardware and software. For

example, an ATM gateway can be used to connect a Fibre Channel link to an ATM connection.

GBIC

Gigabit interface converter. A removable serial transceiver module that allows gigabaud physical-level transport for

Fibre Channel and gigabit Ethernet.

Gbps

Gigabits per second (1,062,500,000 bits/second).

GBps

Gigabytes per second (1,062,500,000 bytes/second).
