fixed port
usage
In Web Tools EZ, fixed port usage means that a set of switch ports is designated to be used as HBA
(host) ports and a set of ports is designated to be used as storage ports.
fixed zoning In Web Tools EZ, fixed zoning is a preconfigured default zoning setup that is set at the factory. It
enforces the rule of one HBA port zoned with one storage port. Fixed zoning is hard zoning; each zone
member is identified by the default switch domain (1) and a port number. Fixed zoning is set up based
on fixed port usage.
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. See also F_Port, Fx_Port.
flash Programmable nonvolatile RAM (NVRAM) memory that maintains its contents without power.
frame The Fibre Channel structure used to transmit 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 Brocade routing protocol for Fibre Channel switches.
FTP File Transfer Protocol.
Fx_Port A fabric port that can operate as either an F_Port or FL_Port. See also F_Port, FL_Port.
G
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.
Gbit/sec Gigabits per second (1,062,500,000 bits/second).
GUI A graphic user interface, such as Brocade Web Tools arbitrated-loop topology and Brocade Fabric
Manager.
H
HA High availability. A set of features in Brocade SilkWorm switches that is designed to provide maximum
reliability and nondisruptive replacement of key hardware and software modules.
header A Fibre Channel frame has a header and a payload. The header contains control and addressing
information associated with the frame.
host A computer system that provides end users with services like computation and storage access.
HTTP Hypertext Transfer Protocol. The standard TCP/IP transfer protocol used on the World Wide Web.
