Glossary director An intelligent Fibre Channel switching device providing any-to-any port connectivity between nodes (end devices) on a switched fabric. The director sends data transmissions (data frames) between nodes in accordance with the address information present in the frame headers of those transmissions. DNS name Domain name system (or domain name service). Host or node name for a device or managed product that is translated to an internet protocol (IP) address through a domain name server. 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 attribute, blocked connection, connectivity capability, dynamic connectivity, and unblocked connection. dynamic connectivity The capability that allows connections to be established and removed at any time. E_D_TOV See error-detect time-out value. E_Port See expansion port. 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 Product Manager application and supports director configuration, statistics monitoring, and basic operation. error-detect time-out value (E_D_TOV) - User-specified value that defines the time a director or switch waits for an expected response before declaring an error condition. 10 Directors and Edge Switches Glossary
