hi,
its always advisable to run on separate machines since you can add and
remove servers for each service
as per load.
NFS is problematic on linux :-)) Probably you havent done enough fine
tuning on the O/s.. anyways.. its your call.
Just FYI, we have tested reliability and performance and we managed to
achieve a very high reliability
rate of writes on simultaneous user performance - close to 99.996 % :-)
it is pretty good for this load i guess.. anyways for your comfort go to
Netapps instead of depending on a
compaq solution if u dont trust Redhat or Suse:-)
Also clustering would never be the solution for scalability beyond millions
of subs until u think of a NAS solution
in messaging scalability.. since single server locking of users always
results in downtime of users when that
server is down, and clustering multiple servers is never a cost effective
and good technical option specially
when the application doesnt support the same, and u r dependant on the O/s
or hardware for the same.
Thanx and Rgds

Do you run pop3d on separate machines, or all together?
Also I will never run NFS, it's too problematic and error
prone (especially on Linux). GFS is million times better of a solution,
and Compaq is working on SSI clustering for Linux
