This paper examines the performance implications of scaling up an Exchange Server 2010 mailbox server virtual machine in vSphere 5 in comparison to vSphere 4.1 (increasing the number of virtual CPUs in the virtual machine) and scaling out with multiple Exchange Server 2010 virtual machines (increasing the number of virtual machines to the host). This paper includes data showing significant performance improvements of vMotion and Storage vMotion in vSphere 5.
