I'm currently implementing this setup for our web hosting company, and

better if you have your applications using some sort of directory
structure for authentication, like LDAP or MySQL, (such as vpopmail,
proftpd, apache auth, etc.) If I need additional throughput, then
probably upgrade to Gigabit ethernet between the app servers and the
file server, and add more app servers. Also, eventually I'll be
a redundant file server that mirrors the main one..
I'm just planning the same thing, but I'm not sure about reliability
What about using something like AFS or Coda? These fs supports ACL,
caching, and also file replication.
I researched these a little bit before deciding on NFS. Coda didn't
have a production/stable version out when I researched, so that ended
that relationship for me.
AFS seemed like it was better suited for disconnected networks, such as
laptops that can come on and offline, and can sync their files up when
they're online. Although it would probably work in this situation, I
didn't trust it enough to run it in such a mission-critical portion of
NFS, while being older, having issues with locking, etc., still seemed
to me the best choice, just because of its longevity. I can work
around the locking issues(use LDAP directories for distributed info,
Maildir for mailboxes, etc.)
Now if MySQL would only offer multiple-master replication, we'll be
