Abstract: A storage area network (“SAN”) includes one or more digital data processors that are coupled for communication with one or more storage devices (e.g., LUNs) over an interconnect. The improvement provides a mechanism for hierarchically displaying, e.g., on the administrator console or other output device, portions of the SAN topology. It includes a process that generates for application to the output device a plurality of graphical object that represent “segments” of the SAN and/or components of the SAN, along with the interconnections between them. The process selectively responds to operator/administrator selection of any of the graphical objects that represent a segment by regenerating the display to depict the interconnected segments and/or components that make up that segment.

Abstract: A storage area network (“SAN”) includes one or more digital data processors that are coupled for communication with one or more storage devices (e.g., LUNs) over an interconnect. The improvement provides a mechanism for hierarchically displaying, e.g., on the administrator console or other output device, portions of the SAN topology. It includes a process that generates for application to the output device a plurality of graphical objects that represent “segments” of the SAN and/or components of the SAN, along with the interconnections between them. Thus, for example, a first graphical object displayed on the output device can represent a first segment of the SAN. A second graphical object can represent either a second segment of the SAN or a component (e.g., host or storage device) of the SAN. And, a third graphical object can represent the portion of the interconnect that couples the segments/component represented by the first and second graphical objects.
