A ServerNet cluster is a collection of NonStop servers connected together using the ServerNet
protocol. There are two generations of ServerNet clusters:
The first-generation ServerNet cluster is built around the HP NonStop Cluster Switch
(model 6770) and can support up to 24 nodes. It is built using one of the star topologies
(star, split-star, or tri-star).
For information about ServerNet clusters built with the star topologies, see the ServerNet
Cluster Manual, the ServerNet Cluster 6770 Hardware Installation and Support Guide,
and the ServerNet Cluster Supplement for NS-Series Servers.

The second-generation ServerNet cluster is built around the HP NonStop ServerNet
Switch (model 6780) and can support up to 64 nodes. It is built using a layered topology.
For information about ServerNet clusters built with the layered topology, see the
ServerNet Cluster 6780 Planning and Installation Guide , the ServerNet Cluster 6780
Operations Guide, and the ServerNet Cluster Supplement for NS-Series Servers.

Using the OSM Service Connection, you can monitor and maintain the ServerNet cluster
resources. The hardware resources in a cluster differ depending on the topology of the
ServerNet cluster. For details about the resources that make up each type of ServerNet cluster,
