This procedure creates two clusters: one for the server nodes and one for configuration database nodes. The nodes in the server cluster point to the servers in the configuration database cluster for their configuration data. The nodes in the configuration database cluster replicate their data between each other.
The following diagram illustrates this installation scenario:
To install a separate configuration database, you first install the configuration database on servers in a cluster, then install the server on nodes in a separate cluster. At least one configuration database must be running before you can install the server.
Note: In the case of a separated database configuration cluster setup, as shown here, you can apply load balancing only to the Spectrum server cluster. You cannot apply load balancing to the separated database cluster.
