I really doubt AFS's storage usage profile will be any different than any
other disk-intensive service at that level.  I would go with whatever you
would use for any other disk-intensive service, such as a database server.

I personally doubt you're going to see significant performance differences
at the AFS level between FC and Ethernet, since I don't think the AFS
server is going to be able to saturate either channel.
