Network attached storage (NAS) has proven itself as a versatile storage resource, allowing storage to be quickly and cost effectively added to the local network. NAS appliances are noted for their convenience, offering dedicated internal storage that is relatively straightforward to identify and manage. The biggest issue for NAS appliances is avoiding network bottlenecks and supporting expansion without having to proliferate additional appliances across the network. The product snapshots in this chapter highlight key specifications for a cross section of major NAS appliance products. The following products were selected based on input from industry analysts and SearchStorage.com editors, and specifications are current as of August 2007.

The following specifications have been provided by vendors and are periodically updated. Vendors are welcome to submit their updates and new product specifications to Matt Perkins.
