Evaluate Hyper-V Server 2012
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. Organizations consolidating servers where no new Windows Server licenses are required or where the servers being consolidated are running an alternative OS may want to consider Microsoft Hyper-V Server.
Microsoft Hyper-V Server 2012 provides a simple and reliable virtualization solution to help organizations improve their server utilization and reduce costs.
