FIFO
First in, first out. A storage method that retrieves the item stored for the longest time.
FL_Port
Fabric loop port. A port that is able to transmit under fabric protocol and also has arbitrated loop
capabilities. Can be used to connect an NL_Port to a switch.
frame
The Fibre Channel structure used to transmit data between ports. Consists of a start-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 on site.
FSP

or topology.
FSPF
Fabric shortest path first. The HP StorageWorks routing protocol for Fibre Channel switches.

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.
HA
High availability. A set of features in HP StorageWorks switches that provides maximum reliability and
nondisruptive replacement of key hardware and software modules.
HTTP
Hypertext Transfer Protocol. The standard TCP/IP transfer protocol used on the World Wide Web.
ID_ID
Insistent domain ID. A parameter of the configure command in the HP Fabric OS.

failovers, and fabric reconfigurations.
IOCTL
