Ed-64M - EMC Connectrix EC-1200 Planning Manual

Glossary
DID Destination ID, the address identifier that indicates the targeted
destination of the transmitted frame.
Director (1) An Enterprise-Class Fibre Channel switch. The Connectrix
ED-64M Director is a fully redundant Fibre Channel switch,
containing: dual power supplies, fan modules, CTP cards, SBARs,
and multiple FPMs, all hot-swappable. (2) A board-level module in
the Symmetrix that provides the interface between host channels (via
an associated adapter module in the Symmetrix) and Symmetrix disk
devices. (This description is presented here only to clarify a term used
in other EMC documents.)
DNS See Domain Name Service Name.
Domain ID A number (1 to 31) that uniquely identifies a switch in a fabric. A
distinct Domain ID is allocated to each switch in the fabric by the
principal switch.
Domain Name Host or node name for a system that is translated to an IP address
Service Name through a Name Server. All DNS names have a host name component
and, if fully qualified, a domain component, such as host1.abcd.com. In
this example, host1 is the host name.
DWDM Dense Wavelength Division Multiplexing, a process in which
different channelsof data are carried at different wavelengths over
one pair of fiber-optic links. This is in contrast with a conventional
fiber-optic system in which only one channel is carried over a single
wavelength traveling through a single fiber.
DS-xxM A general term that represents any or all of these Connectrix models:
DS-16M (1 Gb), DS-32M (1 Gb), DS-16M2 (2 Gb), DS-32M2 (2 Gb).
E
E_D_TOV See Error Detect Time Out Value.
E_Port Expansion Port, a physical interface within the Fibre Channel switch
that attaches to another E_Port on a Fibre Channel switch through an
interswitch link.
Embedded Web A management interface embedded on the switch's code that offers
Server features similar to (but not as robust as) the Connectrix Manager and
Product Manager.
