Microsoft Clustering Services is a topic we get many questions on. Specifically, we spend time talking about the configurations that are possible when deploying MSCS on vSphere and what is and isn't supported. After talking to many customers it became apparent that there was a good amount of confusion as to what was supported by VMware.
To try and clear things up we decided it would be best to lay out, as clearly as possible, the configurations that are supported by VMware. KB 1037959 provides clear guidelines and vSphere support status for running various Microsoft clustering solutions and configurations.
