HP StorageWorks Fabric OS 5.0.0 Command Reference Guide (AA-RW1MA-TE, May 2005)

768 Glossary
FSPF Fabric shortest path first. The HP routing protocol for Fibre Channel switches.
FSS Fabric OS state synchronization. The FSS service is related to high availability (HA). The
primary function of FSS is to deliver state update messages from active components to their
peer standby components. FSS determines if fabric elements are synchronized (and thus FSS
compliant).
FTP File Transfer Protocol.
FTS Fiber Transport Services.
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 half duplex.
Fx_Port A fabric port that can operate as either an F_Port or FL_Port. See also F_Port, FL_Port.
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.
Gb/s Gigabits per second (1,062,500,000 bits/second).
GB/sec Gigabytes per second (1,062,500,000 bytes/second).
GLM Gigabit Link Module. A semitransparent transceiver that incorporates serializing/deserializing
functions.
GMT Greenwich Mean Time. An international time zone. Also known as UTC.
GUI A graphic user interface, such as HP Advanced Web Tools arbitrated-loop topology and HP
Fabric Manager.
HA High availability. A set of features in HP switches that is designed to provide maximum
reliability and nondisruptive replacement of key hardware and software modules.
half duplex A mode of communication that allows a port to either transmit or receive frames at any time
except simultaneously (with the exception of link control frames, which can be transmitted at
any time). See also full duplex.
hard address The AL_PA that an NL_Port attempts to acquire during loop initialization.
Hardware
Translative Mode
A method for achieving address translation. There are two hardware translative modes
available to a QuickLoop enabled switch: Standard Translative Mode and QuickLoop Mode.
HBA Host bus adapter. The interface card between a server or workstation bus and the Fibre
Channel network.
HCPLD High-capacity PLD. Refers to both CPLDs and FPGAs.
header A Fibre Channel frame has a header and a payload. The header contains control and
addressing information associated with the frame.
