Overview of Cluster Configuration
In MarkLogic clusters, a common configuration is to have one group defined for the evaluator nodes (hosts that service query requests) and another group defined for the data nodes (hosts to which forests are attached).
The Cluster configuration page found in the Admin Interface enables you to configure FIPS 140-2 mode for a cluster and to couple local and foreign clusters. For a description of each configuration option, see the help tab of the group configuration page in the Admin Interface. For a discussion of how clustering works in MarkLogic Server, see Clustering in MarkLogic Server in the Scalability, Availability, and Failover Guide.
