A ServerNet cluster is a collection of NonStop S-series 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).

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

.

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,
see

Cluster Resources

.

For information about ServerNet clusters built with the layered topology, see the ServerNet
Cluster 6780 Planning and Installation Guide
or the ServerNet Cluster 6780 Operations Guide.

For differences in managing ServerNet clusters built with the star topologies, see
