Server virtualization, also known as hardware virtualization, is a hot topic in the Information Technology (IT) world because of the potential for serious economic benefits. Server virtualization enables multiple operating systems to run on a single physical machine as Virtual Machines. With server virtualization, one can consolidate workloads across multiple underutilized server machines onto a smaller number of machines. Fewer physical machines can lead to reduced costs through lower hardware, energy, and management overhead, plus the creation of a more dynamic IT infrastructure. This paper briefly touches upon Hyper-V and Cluster Extension (CLX) key features, functionality, best practices and various use cases. It also objectively describes the various scenarios in which Hyper-V and CLX complement each other to achieve the highest level of disaster tolerance.
