"HA Cluster-In-A-Box" Configuration:
Configuration The "HA Cluster-In-A-Box" allows for failover of users'
applications between hardware partitions (nPars) on a single Superdome system. All providers of
mission critical solutions agree that failover between clustered systems provides the safest
availability-no single points of failures (SPOFs) and no ability to propagate failures between
systems. However, HP supports the configuration of HA cluster software in a single system to allow
the highest possible availability for those users that need the benefits of a non-clustered solution,
such as scalability and manageability. Superdome with this configuration will provide the greatest
single system availability configurable. Since no single-system solution in the industry provides
protection against a SPOF, users that still need this kind of safety and HP's highest availability
should use HA cluster software in a multiple system HA configuration. Multiple Serviceguard or
Serviceguard Extension for RAC clusters can be configured within a single Superdome system (i.e.,
two 4-node clusters configured within a 32-processor Superdome system).
Multi-system High
Availability
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
