I agree. I actually object to the analysts' persistence in breaking this market into components based on storage network architecture. More appropriately, the market could be divided by the purpose of the storage subsystems. For example, content management/delivery versus centralized storage. This is a little fuzzy, but the nature of the devices appropriate for these applications is pretty clear. Content management/delivery requires techniques to store, retrieve, distribute, and cache information from centralized storage to the edge of the enterprise, where the storage and communications networks intersect. Centralized storage requires techniques to store and retrieve large amounts of data from and to multiple large application serving computers. The architectures of NAS and EMC's direct channel attachment have the fundamental performance characteristics to serve each of these niches, respectively. NTAP's NAS is the gorilla of content management/delivery because it is the p/p leader with bte and the software tools to perform the job. NTAP's filers for storage, content delivery software, and caching appliances fulfill the requirements of this environment. EMC's SAN (Symmetrix) is the king of centralized storage because of its throughput capacity as provided by direct channel attachment to mainframes and UNIX servers, and the capacities of SAN storage network topologies. EMC's NAS offering is an attempt to apply NAS topology to the centralized storage application.
