That is exactly my point. Most people have a common definition of the terms. Just like I hear many people say something like "Do you have OpenView?" I know that they usually mean OpenView Network Node Manager but OpenView is a suite of products and Network Node Manager is but one product in that suite. People have their common terminology and use it even though it is not quite accurate.

Network Appliance makes NAS devices that connect via ethernet. However, they also sell fibre channel HBAs for their Filers to allow direct attach via SAN. Conversely, there are all kinds of SAN disk arrays out there that attach via fibre channel but you can easily buy a NAS head and connect via ethernet and call it a NAS device.

This type of stuff really confuses people and that is why I offered two definitions and said that most people refer to SANs as their fibre channel network and the arrays on it. It is not fair to say they have nothing to do with each other because they do coexist with each other.
