Historian in a Cluster Environment

Historian works with the Microsoft Cluster Service Manager to ensure high availability of the Historian server. If the primary Historian node in the cluster experiences difficulties, Historian is automatically started on another node to take over. Server high availability is managed through the Microsoft Cluster Service Manager.
