A user interface includes a graphical topological representation of an information system. Information is collected regarding connections between switches, storage nodes and computer nodes in the information system. Any sub networks in the system are identified based on the collected information and classified as LANs or SANs. Connections between the various components are determined, and a layout of any identified LANs, computer nodes, SANs, and storage nodes is established for generating the topological representation in the user interface. The graphical topological representation of the information system is displayed in the user interface with the LAN icons, computer node icons, SAN icons and storage node icons laid out in a matrix-like arrangement of columns and rows, such that for LANs, computer nodes, SANs and/or storage nodes that are connected to each other, the corresponding icons are located on or near a same row in the graphical topological representation.
