Glossary
duplex connector An optical fiber component that terminates jumper cable fibers in one
housing and provides physical keying for attachment to a duplex
receptacle (D).
duplex receptacle A fixed or stationary optical fiber component that provides a keyed
attachment method for a duplex connector (D).
dynamic connection A connection between two ports, established or removed by the
directors and that, when active, appears as one continuous link. See
connectivity attribute. See also allowed connection; blocked connec-
tion; connectivity capability; dynamic connectivity; unblocked con-
nection.
dynamic connectivity The capability that allows connections to be established and removed
at any time.
dynamic random
access memory DRAM. Random access memory that resides in a cell comprised of a
capacitor and transistor. DRAM data deteriorates (that is, is dynamic)
unless the capacitor is periodically recharged by the controlling
microprocessor. DRAM is slow, but relatively inexpensive (D). Con-
trast with static random access memory.

EAF See enhanced availability feature.
EDI See electronic data interchange.
E_D_TOV See error-detect time-out value.
EE-PROM See electronically erasable programmable read-only memory.
EFC Enterprise Fabric Connectivity. The Fibre Channel protocol infra-
structure made up of switches and directors in an enterprise. EFC is
used to describe products such as EFC Management, EFC Manager
application, or EFC Server.
EFC Audit Log Enterprise Fabric Connectivity Audit Log. Log displayed though the
EFC Manager application that provides a history of user actions per-
formed at the EFC Server through the EFC Manager application. This
information is useful for system administrators and users. See also
Audit Log; EFC Event Log; EFC Product Status Log; EFC Session Log.
