okay..I know that most people already knows that running DAG servers on Hyper-V cluster and UM on Hyper-V now is supported… Really Good news.
Microsoft already has a techNet resources covering that but also now we have a white paper for that.
The purpose of this paper is to provide guidance and best practices for deploying Microsoft® Exchange Server 2010 in a virtualized environment with Windows Server® 2008 R2 Hyper V™ technology. This paper has been carefully composed to be relevant to organizations of any size.
Mahmoud Magdy (Ingazat Information Technology) and Mohamed Fawzi (LINK Development) talking about Windows 2008 R2 SP1 and Exchange 2010 SP1 new features in 5 min TechTalk, the first Ch9 Arabic post :)
We are planning to release more video in the next few months.. keep tuned, more to come :)
We all have been tought that Exchange 2010 DAG cannot be installed on a hyper-v Cluster or ESX Cluster (generally any hypervisor clustering), this is a correct statement but not entirely true.
the correct statement that Installing Exchange 2010 DAG is not supported on Hypervisor Clustering only when you confiure the VM that hosts the Exchange as highly available machine, thus you control the High availability of he VM using clustering.
if you Install Hyper-v or ESX clustering, you can Install Exchange 2010 DAG normally on a VM that is hosted on any single host of the Hypervisor cluster as long as this machine is not highly available from the Hypervisor point of view meaning that you cannot move it using live migration or Vmotion.
you can now install the DAG on your Hypervisor Cluster physical server normally, don’t make the VM highly available, size the IOPs and Memory and you are fine.
Hope that this helps you in your virtualization and Exchange Project
