How are you ensuring that you're choosing the right network storage options? Network World's Deni Connor evaluates the networked storage options.

We tested Visionael's Visionael 6.4, Compuware's EcoPredictor 3.2, Microsoft's Visio Professional 2002 with Enterprise Network Tools, NetRule 4.0 from Analytical Engines and Bert Houtriet's shareware Didyma 1.72. In the last newsletter, we looked at EcoPredictor and NetRule. This time, we turn our attention to the rest, none of which met our criteria for a full-featured network design tool. Visionael is a superior tool for discovering, designing and documenting a network, but it didn't let us simulate application or network activity. Didyma can discover, design and document a network, but it can't simulate the effect of the changes you make. Microsoft's Visio is an excellent network design diagramming tool that, with the Enterprise Network Tools option, can discover and document a network, but it can't simulate application activity within the network. Visionael was the most complex and comprehensive of the products we tested. In the lab, its discovery feature used SNMP-based software probes to gather network layout and device identification data. Optional Microsoft System Management Server and Hewlett-Packard's OpenView software probes can collect data from those respective products. Because Visionael is as much a network and system inventory tool as a design tool, the discovery process collects far more computer and network device detail, such as basic I/O system versions and adapter slot usage, than a network planner needs. During design sessions, the diagramming tool collects this same level of detail about proposed network components. Even while you're designing network changes in Visionael, it continues to monitor the existing network to ensure its baseline data is accurate. In our tests, Visionael stored network component data relationally in an Oracle 8i database. Visionael also offers versions of its product that work with Sybase Adaptive Server or Microsoft SQL Server. Visio's Enterprise Network Tools option collects the same information regardless of whether a network node is a router or a computer. Visio stores its diagramming specifications and network device details in a proprietary binary format. In addition to rendering the network drawing in hard copy or Web page form, Visio can produce Web pages, Visio table shape or XML-based asset reports containing asset types, asset owners, names and manufacturers. Visio can also export data to Microsoft Excel, Microsoft Access or a relational database via Open Database Connectivity. While it doesn't have a simulation feature for modeling the behavior of a proposed network design, Didyma has a monitoring function that can periodically ping existing network devices to detect their health. Its discovery feature updates the current design workspace with only the identities of the devices it finds, which makes for even more data entry effort during the design sessions that follow a discovery operation. Furthermore, as it collects data during a design session, Didyma doesn't distinguish among the various types of network nodes. Whether a node is a computer, router or other device, Didyma, like Visio, asks for the same information. This consists of name, IP address, SNMP community string, interface type (Ethernet, token ring or serial), media access control address, DNS name, whether to monitor the node and whether to include it in reports.
