We’ve been virtualising Exchange Server 2007 since it was first released but this week Microsoft has announced their official support policies for virtualised Exchange environments.  It is a bit heavy on the Hyper-V but also references the list of support partners for non-Microsoft hardware virtualisation.  When I checked this earlier in the week VMWare was a notable absence but today Dugie confirmed for me that they’ve been added to the list, which now stands as follows:

• Cisco Systems, Inc.
• Citrix Systems, Inc.
• Novell, Inc.
• Sun Microsystems
• Unisys Corp.
• Virtual Iron Software
• VMware, Inc.

If you’re planning an Exchange Server 2007 deployment using a virtualisation platform be sure to read Microsoft’s recommendations for sizing virtual machines.
