A ServerNet cluster is built using one of several topologies. The hardware resources in a cluster
differ depending on the topology of the ServerNet cluster.
ServerNet clusters using one of the star topologies are built with the HP NonStop Cluster
Switch (model 6770) and can support up to 24 nodes.
ServerNet clusters using the layered topology are built around the HP NonStop ServerNet
Switch (model 6780) and can support up to 64 nodes.
