Planning the Fabric
Hyper Messaging Protocol (HMP)
Chapter 2
34
There are many variables that can impact HyperFabric performance. If you are
considering a configuration that is beyond the scope of the following HP supported
configurations, contact your HP representative.
Point to Point
Large servers like HP’s Superdome can be interconnected to run Oracle RAC 9i and
enterprise resource planning applications. These applications are typically consolidated
on large servers.
Point to point connections between servers support the performance benefits of HMP
without investing in HyperFabric switches. This is a good solution in small
configurations where the benefits of a switched HyperFabric cluster might not be
required (see configurations A and B in Figure 2-4).
If an HMP application is running over the HyperFabric and another node is added to
either of the point to point configurations illustrated in Figure 2-4, it will be necessary to
also add a HyperFabric switch to the cluster.
