With Hyper-V, it is now easier than ever for organisations to take advantage of the cost savings of virtualisation, and make the optimum use of server hardware investments by consolidating multiple server roles as separate virtual machines that are running on a single physical machine. Use Hyper-V to efficiently run multiple operating systems, Windows, Linux, and others, in parallel, on a single server. Windows Server 2012 RC extends this with more features, greater scalability and further inbuilt reliability mechanisms.
Significant improvements have been made across the board, with Hyper-V now supporting increased cluster sizes, a significantly higher number of active virtual machines per host, and additionally, more advanced performance features such as in-guest Non-Uniform Memory Access (NUMA). This ensures customers can achieve the highest levels of scalability, performance and density for their mission-critical workloads.
This paper will focus on comparing Windows Server 2012 Release Candidate (RC) Hyper-V, with the standalone VMware vSphere Hypervisor, also known as ESXi, and vSphere 5.0, across 4 key areas:
