VMware recently released a whitepaper showing the performance scalability of SharePoint Server 2007 on VMware vSphere 4.1. This paper demonstrates that vSphere 4.1 exhibits high performance and includes advanced features that can improve the overall user experience in multi-tier applications such as SharePoint.

Results of the experiments, in which up to 171,600 heavy SharePoint users were supported on a single physical server,  highlight the benefits gained by the ability to easily deploy additional SharePoint virtual machines as needed to satisfy changing demands

This paper also discusses some of the advanced features of VMware vSphere 4.1—such as memory compression, NUMA-aware resource management, and inter-VM communication—that allow vSphere to efficiently virtualize resource-intensive and latency-sensitive applications. The paper concludes with a set of recommended best-practices for achieving optimal SharePoint performance on VMware vSphere 4.1.
