Has anyone had experience (good or bad) with VMWare GSX Server running

Here is the situation. We are planning on rolling out some new boxes
to replace an existing box. Currently this box (Sun V860) is running
web services, database services, mail for students, and is an
instructional box for compiling code, and web scripting among other
things.
We are planning on doing one of two things, either using VMWare and
splitting up the services or using Solaris Zones. The box(s) has to be
able to access data stored on the SAN (Fiber Channel HBA's). The
boxes(VM's), or Zones would be split up accordingly:
Database box: Oracle, Postgres, and MySQL
Mail: Sendmail, POPS, and IMAPS (roughly 25,000 mailboxes)
Web: Apache, PHP, mod_ssl
Interactive Logins: Compilers and such.
Any information about any experiences with VMWare and CentOS, under
similar load would be helpful. I will probably make this same post on
the Sun Solaris Mailing List, and VMWare's forums. Thanks in advance!
I dunno, but I'm curious why you want to run so many VMs' or zones?
the database/mail/web stuff would probably all run most efficiently in
the 'host' OS... I can see some advantages to running student
interactive logins in a VM or zone for security isolation.
its that, or I'd put the infrastructure things (email, school web,
school databases) on a dedicated and secure hardware platform, then put
all the instructional stuff on a seperate hardware platform. I don't
like having too many eggs in one basket.
