Thank's Jake.
This is the architecture was projected (not by me ... ;) ):
Sun Cluster with Solaris 9 (for Mysql and NFS)
one pop on Solaris 9
on pop on Red Hat EL4-U2
on SMTP on Red Hat EL4-U2
Is it possible to have an architecture like this? Where can I found
some documents for helping me in this setup?
I've never installed qmail on Solaris, so I've never looked for
documents on it.
I do not think there are many documents out there concerning this type
of setup, but google would be your best bet.
I normally use pop and smtp on the same qmail front end machines,
allowing them to be dual purpose. You can load-balance using DNS
(round-robin setup). And make sure your NFS is on a separate out of band
network, but fast equipment (at least 100M network connections, gigabit
preferable). Depending on your load, the filesystem for the NFS may be a
consideration as well - some RAID implementations are slower on the
writes than others, but we're talking loads of 15,000 users or more for
this to be noticeable.
