EMI Electromagnetic interference. Any electromagnetic disturbance that interrupts,
obstructs, or otherwise degrades or limits the effective performance of
electronics/electrical equipment.
Emulex A brand of host bus adapter (HBA).
enabled zone con- The currently enabled configuration of zones. Only one configuration can be
figuration enabled at a time, but since multiple configurations can be defined in the
database, a new configuration can be easily enabled.

end-to-end flow A process that governs flow of Class 1 and 2 frames between N_Ports.
control See also EE_Credit.
entry fabric The basic HP software license that allows one E_Port per switch.
EOF End of frame. A group of ordered sets used to mark the end of a frame.
E_Port Expansion port. A type of switch port that can be connected to an E_Port on
another switch to create an ISL.

EPPID Dynamic identifier for the chassis in which a port card resides. The identifier is
written to the card each time the card is inserted into a chassis.
error As it applies to the Fibre Channel industry, a missing or corrupted frame,
timeout, loss of synchronization, or loss of signal (link error).

ESCON Enterprise Systems CONnection. An IBM S/390 fiber-optic channel that
transfers 17 Mbps over distances up to 60 km depending on connection type.
ESCON allows peripheral devices to be located across large campuses and
metropolitan areas.

Ethernet The most widely used LAN access method, defined by the Institute of Electrical
and Electronics Engineers (IEEE) as the 802.3 standard.
EVMd Event management database. Delivers FDMI-related events.
exchange The highest-level Fibre Channel mechanism used for communication between
N_Ports. Composed of one or more related sequences, it can work in either
one or both directions.
EX_Port A type of E_Port that connects an MP Router to an edge fabric. EX_Ports limit
the scope of fabric services scope but provide device connectivity using FC-NAT.
exported device A device that has been mapped between fabrics. A host or storage port in one
edge fabric can be exported to any other fabric by using LSAN zoning.
fabric A collection of Fibre Channel switches and devices, such as hosts and storage.
Also called switched fabric.
See also cascade, SAN, and topology.
fabric application A device that enables fabric-based storage applications such as mirroring, data
platform migration, snapshots, and virtual tape. The HP StorageWorks Fabric Application
Platform can run in a central location, process data at wire speed, and reside
in existing data paths.
Fabric Manager Optionally licensed HP StorageWorks software. Fabric Manager is a GUI
that allows for fabric-wide administration and management. Switches can be
treated as groups, and actions such as firmware downloads can be performed
simultaneously.
