In this last part of three Aaron Denton shares his experiences after ther upgrade from Hyper-V 1.0 to Hyper-V 2.0.
In the previous posts for this series, I discussed why we decided to upgrade our virtual machine host servers from Windows Server 2008 to revision 2. I also outlined the implementation plan.

Cluster Shared Volumes
While there may not be any performance or high availability gains from this feature, I consider it a great one from an administrative standpoint.
To illustrate my point, consider the number of disks needed to have clustered Exchange 2007 servers running as VMs in revision 1. For each server one disk for Windows, a disk for each database, and a disk for each set of transaction logs is needed. With just one mailbox store, six iSCSI disks are needed. When you add in the disks you need to run Hub Transport and Client Access servers you easily need 8-10 disks just for email.
