Hyper-V can enable high-availability using Windows Server Failover Cluster Manager. This allows you to create a virtual infrastructure which is resilient to server failures.
A typical Hyper-V failover cluster setup consists of 2 or more servers, which share clustered network and clustered storage resources. In the event of a server failure, the clustered resources are seemlessly failed over to the next available server. To the end user, there is generally no impact on services running on the server.
Failover is an automated process which is managed by the Operating System. Hyper-V enables you to create clustered storage and clustered networking which are an infrastructure requirement for cluster failover manager. (more…)
