Microsoft Hyper-V Server is a dedicated stand-alone product that contains the hypervisor, Windows Server driver model, virtualization capabilities, and supporting components such as failover clustering, but does not contain the robust set of features and roles as the Windows Server operating system. As a result, Microsoft Hyper-V Server produces a small footprint and requires minimal overhead.

Hyper-V Server 2012 R2 is a hypervisor-based server virtualization product that enables you to consolidate workloads, helping your organization improve server utilization and reduce costs.
