The general idea seems to be that since Exchange/SQL can be so heavy on CPU and/or I/O that you may not be able to get any other VM on the box aside from Exchange or SQL itself. This will all depend on the working environment for those applications and the type of storage you use for VMware. That being said, there is a lot to be said about the DR that is offered by VMware (or virtualization in general), even if you can only get 1 VM on a physical box. That VM is now hardware independent, makes for much quicker bare metal restores from image level backups, resource scheduling advantages, etc. From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Patrick Sent: Friday, January 30, 2009 8:30 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Exchange and virtualization Thanks. So it would be recommended to install both on physical boxes?

Note: If you have any problem with Exchange, Microsoft PSS will not support you J Thanks and Regards PRABHAKAR KAMUNI | ECG- De Beers Project | Tech Lead Unisys Global Services India | 135/1 Residency Road | Bangalore | Business Phone +91 4159 4828|Net 759 4828 Mobile: 0091-9945333367 THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

I am sure I have read somewhere that it is not adviceable to run either Exchange or Sql on VM's. Anyone got any documentaion / whitepaper to back that up, or have I got it wrong. Thanks Patrick
