Tech Note 98: How to Set Up a Wonderware Historian Cluster

This tech note walks through the setup of Wonderware Historian 9.0 running on a Microsoft Windows 2003 cluster for high availability and failover purposes. By implementing a two or more node cluster, it allows avoiding extended downtime due to hardware failure by allowing the software to failover to a secondary node or other node in the case of failure of the active node.

Please note that this allows for high availability of the server and software but by itself does not provide true data redundancy.
