Cluster support overview

To share configuration information between appliances and provide failover for services, we can configure your ISAM appliances into clusters.

Every cluster has a primary master and up to three back-up masters, known as the secondary, tertiary and quaternary masters for high availability of cluster services.

By default, an individual appliance is configured as the primary master of a stand-alone cluster. We can configure other appliances to join the cluster as nodes. When an appliance is configured as a node, it can access and share the configuration information of the primary master.
