EMI Electromagnetic interference. Any electromagnetic disturbance that interrupts,
obstructs, or otherwise degrades or limits the effective performance of
electronics/electrical equipm ent.
Emulex A brand of host bus adapter (HBA) .
enabled zone con -
figuration
The currently enabled config uration of zones. Only one configuration can be
enabled at a time, but since multiple configurations can be defined in the
database, a new configuration can be e asily enabled.
See also defined zone configuration and zone configuration.
end-to-end flow
control
Aprocessthatgovernsflow of Class 1 and 2 frames between N_Ports.
See also EE_C redit.
entry fabric The basic HP software license that allows one E_Port per switch.
EOF Endofframe.Agroupoforderedse
ts used to mark the end of a frame.
E_Por t Expansion port. A type of switch p ort that can be connected to an E_Port on
anotherswitchtocreateanISL.
See also ISL and isolated E_Por t.
EPPID Dynamic identifier for the chassis in which a por t card resides. The identifier is
written to the card each time the c ard 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).
See also loop failure.
ESCON Enterprise Systems CONnection. An IBM S / 390 fiber-optic channel that
transfers 17 M bps over distances up to 60 km depending on connection type.
ESCON allows peripheral devices to be located across large c a mpuses and
metropolitan areas.
See FICON
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 m anagement 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 t ype of E_Port that conne cts an MP Router to an edge fabric. EX_Ports limit

exported device A device that has been mapped between fabrics. A host or storage por t 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 a nd storage.
Also called switched fabric.
See also cascade, SAN,andtopology.
fabric application
platform
A device that enables fabric-based storage applications such as mirroring, data
migra tion, 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 Ma n ager is a GUI
that allows for fabric-wide administration and m anagement. Switches can be
treated as groups, and actions such as firmware downloads can be performed
simultaneously.
