Hi all,

I've just bought a dedicated server, and I'm looking 4 the best configuration. I need to run Java (Struts2-hibernate+mysql) applications through Tomcat.

Motherboard supports till 8GB RAM
CPU Intel 2,6GHz Pentium Dual Core
4GB RAM DDR2 667 MHz
2HD SATA 500GB 7200rpm in RAID 1 software

I'm thinking to create 4 virtual servers:
1) Developing Environment. It contains repository (svn) and Trac application (a project management web app.)
2) Test Environment. Identical to Production.
3) Production Environment. Must run Struts2+Hibernate apps.
4) Parking Environment. Dedicated to simple static sites and parked domains.
5) Mysql Environment. To be used and not duplicated from the other virtualizations.
I'd create also a virtual shared storage.

I'm going to use XenServer to virtualize, I'm almost sure about it.
Yet, I still don't know which O.S. is better to use on the virtualizations.. over of all, on test and production environments.


Please, tell me some advice about it.. or about the right strategy in virtualizing the system.
Thanx..
ciao ciao
