Clustered Pairs Configuration

The clustered pairs configuration is a variation on the symmetric configuration. In this configuration, there are two pairs of servers, with each pair operating independently. However, all of the servers are connected by the private interconnects and are under control of the Sun Cluster software.

Clustered pairs can be configured so that you can run a parallel database application on one pair and HA data services on the other. Failover is only possible across a pair.
