Hello all
From my experience of hosting mail and webservers it's advisable to spread those functions across many servers.
=> Web and SQL on one server.
SQL can create quite a bit of I/O, while PHP can create some CPU load. But for low latency SQL and Web should be on the same physical machine.
=> Mail
Mail with say 10'000 users is very very I/O Intensive and needs an own phyical server with no other tasks to reach some acceptable performance.
=> Spamfiltering
SpamAssassin (especialy when you use OCR Modules to do text recognition in picture attachements) and ClamAv are quite CPU intensive and should be put on a separate server. (quite easy if you use MIMEDefang with Sendmail or the latest postfix).
Can such a setup be achieved using plesk?
Preferably with shared storage so that one service could failover from one physical machine to the other in case of hardware failure?
