Failover Example Using Sun Cluster Software

The following figure shows an example of failover strategy for Calendar Server back-end and Messaging Server messaging store. The Calendar Server back-end and messaging store are replicated on separate hardware servers and configured for failover with Sun Cluster software. The number of CPUs and corresponding memory are replicated on each server in the Sun Cluster.
