Hardware virtualisation support for Exchange UM Announced

Microsoft have announced support for the Exchange 2010 SP1 Unified Messaging role on hardware virtualisation. The Technet blog article is here and the official Exchange 2010 system requirements are available here.

Specifically, the UM role has the following requirements -

• Four virtual processors are required for the virtual machine. Memory should be sized using standard best practices guidance.
  
• Four physical processor cores are available for use at all times by each Unified Messaging role virtual machine. This requirement means that no processor oversubscription can be in use. This requirement affects the ability of the Unified Messaging role virtual machine to utilize physical processor resources.
