Any Superdome partition with PA-RISC processors that is protected by Serviceguard or Serviceguard Extension for RAC can
be configured in a cluster with:
Another Superdome with PA-RISC processors
One or more standalone non Superdome systems with PA-RISC processors
Another partition within the same single cabinet Superdome (refer to "HA Cluster-in-a-Box" above for specific
requirements)
Separate partitions within the same Superdome system can be configured as part of different Serviceguard clusters.
Please note that when you add nodes or initially create a cluster, all nodes must be at the same version of the operating
system and Serviceguard. This means that you may have to load an operating system update for hardware enablement of
the newer hardware, even on older systems. Please refer to the "Compatibility and Feature Matrix" at
http://docs.hp.com/hpux/onlinedocs/4076/SG%20SGeRAC%20EMS%20Support%20Matrix_10 3 03.htm

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.
