Standard Cluster model

As described in Cluster models, you can use a Standard Cluster (SC) to provide more capacity than a single SecureTransport Server or to provide a passive standby server to take over processing if an active server fails.

Standard Clustering uses an embedded database in each node. This minimizes external dependencies and overhead and reduces the cost of clustering. SecureTransport synchronizes most configuration changes on all nodes in the cluster.

You can configure a Standard Cluster as an active/active or active/passive (1:1) cluster. You can deploy a maximum of three servers (nodes) in an active/active Standard Cluster. An active/passive Standard Cluster has one active server and one passive standby server.

One node of a Standard Cluster is distinguished as the primary server. The passive node of an active/passive cluster and the one to two other nodes of an active/active cluster are secondary servers. The Administration Tool login screen and banner indicate Primary Server or Secondary Server.

The following topics describe the active/active and active/passive clustering and scheduled tasks, the consolidated log data representation, and the services used for cluster management:
