SAN, as far as I've read, is sold as a separate dedicated 1 Gbps fiber
network with its own servers and routers. These things are e-Expensive,
not particularly cost-efficient for those of us who might use NAS.
(Buzz-acronyms are: SAN - Storage Area Network, and NAS - Network
Addressed Storage.) SAN is beaucoup faster than NAS so the big iron
guys like it. If you run Oracle you probably want SAN, not NAS. The
network drawings I've seen for SAN all show it as a separate, standalone
network that doesn't rely on any of the hardware in the user's network
(aside from connection points, of course).

Cringely this week has an interesting "take" on getting data across a
network. It's part of his Supercomputer story at

http://www.pbs.org/cringely/pulpit/pulpit20011227.html

Basically he's borrowed the idea of bonding 100 Mbps cards together and
then using QNX to control the thing.
