FC-AL
See arbitr
ated loop.
FCoE
Fibr
e Channel o
ver Ethernet. An encapsulation of Fibr
e Channel frames over Ethernet
networks. This allows Fibre Channel to use 10-gigabit Ethernet networks (or higher speeds)
while preserving the Fibre Channel protocol.
Fibre Channel (FC)
A technology for transmitting data between computer devices at a data rate of up to 4 Gbps. It
is especially suited for attaching computer servers to shared storage devices and for
interconnecting storage controllers and drives.
rmware
Software embedded into a storage device. It may also be referred to as microcode.
ash module (FMD)
A high speed data storage device that includes a custom ash controller and several ash
memory sub-modules on a single PCB.
full-duplex
Transmission of data in two directions simultaneously. For example, a telephone is a full-
duplex device because both parties can talk at the same time.
Gbps
Gigabit per second.
gigabit ethernet
A version of ethernet that supports data transfer speeds of 1 gigabit per second. The cables
and equipment are very similar to previous ethernet standards.
GUI
graphical user interface
HA
High availability.
half-duplex
Transmission of data in just one direction at a time. For example, a walkie-talkie is a half-
duplex device because only one party can talk at a time.
HBA
See host bus adapter.
host
One or more host bus adapter (HBA) world wide names (WWN).
