Glossary

D_ID

Destination ID. A Fibre Channel Address of a frame defining the destination node for that frame.

Diplex Communications

In addition to full duplex communications between a pair of nodes, a node can receive from another node, while simultaneously transmitting to a third node independently.

Domain

See Fibre Channel Address.

Duplex (full)

Operation of a data communication link where transmissions are possible in both directions simultaneously.

Duplex (half)

Operation of a data communication link where transmissions are possible in both directions, but only in one direction at a time.

ELS

Extended Link Services support messaging protocol for discovery and dynamic address partitioning.

EMC

ElectroMagnetic Compatibility.

Embedded Node Agent

An in-band Node Agent conducts automatic discovery and display of SCSI and SES targets, SES enclosures.

Enclosure

The box, rack, or set of boxes containing one or more devices. It can provide power, cooling, and other support functions to the devices.

E_Port

Expansion Port. It specifies the interconnection and initialization for a Fibre Channel switch to create an inter-switch link. It is similar to an N_Port and an F_Port.

Fabric

Fibre Channel-defined interconnection methodology that handles routing in Fibre Channel networks.
