Use the Topology Overview to see an overall, high-level view of your storage environment. The topology viewer provides a central location for viewing your storage assets,, and for monitoring, troubleshooting, and performing storage management tasks.
The topology viewer provides a number of functions to help you work with your storage:
Layers of color around an object or group of objects, or small icons, indicating status, health, or other logical attributes for the object or group; overlays can also show the status of connections between objects (see the Connections section below)
Levels of granularity that are consistent across the four primary view categories that are presented in the Topology Overview page. Each level provides a measured level of granularity of detail. For example, the levels for the Computers view are:
The minimap is a small window that is initially located in the upper right corner of any topology view. It provides a miniature representation of the current topology view, and uses color to denote groupings of topology entities. Because topologies can become very large and complex, with many entities and relationships, the minimap shows a small, high-level view of the currently viewed topology. Clicking on the minimap displays a multi-directional cursor that allows you to move the focus of the current topology view in any direction. This makes navigating around complex topologies much easier.
Connections are lines between topology objects. Connections show relationships between objects and also indicate the status of a connection. Between individual objects, the connection status can be shown as healthy (green) or critical (red); connections between group objects, or between an individual object and a group, can also be shown as warning (yellow). Warning status indicates that one or more objects in a group have a health status of critical.
Connections between two individual objects display as a thin line. Connections between group objects, or between a group and an individual object, is a thick line.
In topology and tabular views with many objects and connections, the display can become very cluttered and can make it difficult to determine where problems are occuring. You can use filtering to turn off the display of objects and connections with Normal health status. This will result in just objects and connections with Warning or Critical health to be displayed.
Each topology view, except the initial Topology Overview, includes a tabular version of the topology. The tabular view shows the same information as the graphical topology view, but in a table format. Changes to either view are automatically applied to the other view, keeping both views synchronized.
