Last I heard, DCE (hence DFS) is licensed per node whereas Transarc
only charges for server licenses. Neither are really cost effective
for a small shop.
AFS (and/or DCE/DFS) can be configured as ONE GIANT server, but that
is not the way most shops set it up. You can replicate the various
distributed services, thus improving your availability, reliability
and performance. The caching seems to cut down on a lot of network
traffic; I'm sure there are studies (somewhere) out there.
There is a problem with putting too much data on the client machines.
It is called backups! Backups are easier to do from a few centralized
file servers (or groups of centralized file servers). This technique
can also help to reduce network load.
Later,
