The best way to configure the Development environment

Hello,

I would appreciate if you can share some thoughts
about what components and on what physical boxes need to be
installed on the wM development environment.

I am planning to have three Sun Servers and one WinIntel.
The plan is to have one server as a Development IS
Another one for the clean deployment.
The third server will be dedicated for the wM DBs
and we also planning to use Win Intel server for the Siebel Adapter and
wM Monitoring.

Please advise if you see any pitfalls in this infrastructure.
