Cluster Configurations
The following Geographically Dispersed Cluster solutions fully support cluster configurations using
Superdome systems. The existing configuration requirements for non-Superdome systems also apply to
configurations that include Superdome systems. An additional recommendation, when possible, is to
configure the nodes of cluster in each datacenter within multiple cabinets to allow for local failover in the
case of a single cabinet failure. Local failover is always preferred over a remote failover to the other
datacenter. The importance of this recommendation increases as the geographic distance between
datacenters increases.

From an HA perspective, it is always better to have the nodes of an HA cluster spread across as many
system cabinets (Superdome and non Superdome systems) as possible. This approach maximizes
redundancy to further reduce the chance of a failure causing down time.
