HP-UX 11i v2:

Any Superdome partition that is protected by Serviceguard or Serviceguard Extension for RAC can be configured in a cluster
with:

Another Superdome with Itanium 2 processors
One or more standalone non Superdome systems with Itanium 2 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.

HP-UX 11i v2:

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.

Windows Server 2003

Any Superdome partition that is protected by Microsoft Cluster Service for Windows Server 2003, Datacenter Edition can be
configured in a cluster of up to 8 nodes with:

Another Superdome complex
Another partition within the same single cabinet Superdome with an identical hardware configuration

Furthermore, geographically dispersed clusters are supported utilizing a single quorum resource (Cluster Extension XP for
Windows). Specific Superdome Windows Server 2003 cluster configurations will be announced later in 2003.

Linux

Support of Serviceguard on Linux and Cluster Extension on Linux should be available in late 2003.

Supportability Features

Superdome now supports the Console and Support Management Station in one device.

The optimal configuration of console device(s) depends on a number of factors, including the customer's data center
layout, console security needs, customer engineer access needs, and the degree with which an operator must interact with
server or peripheral hardware and a partition (i.e. changing disks, tapes). This section provides a few guidelines. However
the configuration that makes best sense should be designed as part of site preparation, after consulting with the customer's
system administration staff and the field engineering staff.

Customer data centers exhibit a wide range of configurations in terms of the preferred physical location of the console
device. (The term "console device" refers to the physical screen/keyboard/mouse that administrators and field engineers use
to access and control the server.) The Superdome server enables many different configurations by its flexible configuration of
