Glossary
domain
A Fibre Channel term describing the most significant byte in the node port (N_Port) identifier
for the Fibre Channel device. It is not used in the Fibre Channel small computer system
interface (FC-SCSI) hardware path ID. It is required to be the same for all SCSI targets
logically connected to a Fibre Channel adapter.
domain ID
Number (1 through 31) that uniquely identifies a switch in a multiswitch fabric. A distinct
domain ID is automatically allocated to each switch in the fabric by the principal switch.
domain name service
See DNS name.
dynamic connection
A connection between two ports, established or removed by the directors and, when active,
displays as one continuous link. See also
connectivity capability,
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. Contrast with
random access memory.
E_D_TOV
See error-detect time-out
electronic data interchange
EDI. The electronic transfer of preformatted business documents, such as purchase orders and
bills of lading, between trading partners.
Electronic Industries Association
EIA. The governing body that publishes recommended standards for physical devices and
associated interfaces. For example, RS-232 is the EIA standard that defines computer serial port
connectivity.
Embedded Web Server
(EWS) — Web-based interface that allows administrators or operators with a browser-capable
PC and Internet connection to monitor and manage a director. The interface provides a GUI
similar to the Element Manager application and supports director configuration, statistics
monitoring, and basic operation.
