I just wonder why your setup has NO single point of failure.

to me having NAS or NFS on a reliable machine like a clustered
netapp doesn't seems like a SPOF to me + having ALL users on ALL
servers provides the possibility to do "true" loadbalancing.
I want to have ALL my users on ALL my servers, so that if e.g.. 1 out of 5
servers fails, I still have 4 to serve 100% of the requests, NOT 4 serving
only 80% of the users.
