Highly Available Virtualization With Microsoft Hyper-V and SCV MM 2008
Virtualization solutions can offer significant benefits, helping boost IT efficiency and capacity and providing a robust, simplified environment while also helping significantly reduce costs. However, virtualization can also create single points of failure in critical environments: for example, if an enterprise is running 10 production workloads on 10 separate physical servers, the failure of a single server would likely be inconvenient but not disastrous. However, in a virtualized environment with 10 production workloads running in 10 Virtual Machines (VMs) on a single physical server, the failure of that server could be catastrophic. In addition, computing systems have become such an integral part of enterprise environments that severe consequences can occur when the systems become unavailable.
