13 Cluster Resources
A ServerNet cluster is built using one of several topologies. The resource objects displayed in the
OSM Service Connection for 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.

Resource Objects in the BladeCluster Topology
For NonStop BladeSystems and NS16000 series servers only, the BladeCluster Solution topology
provides a clustering topology that permits connectivity directly through the ServerNet switches in
the Blade enclosure or P-switches, without need for additional cluster switches. The objects displayed
in the OSM Service Connection when the system is a member of a BladeCluster include:
BladeCluster
Local Node
Remote Node
6770 Switch Module
A hardware assembly that provides connectivity for multiple nodes of a ServerNet cluster. The
6770 switch module is used in star, split-star, and tri-star topologies. The subcomponents of the
6770 switch module are the ServerNet II Switch, the AC Transfer Switch, and the Uninterruptible
Power Supply (UPS).
Location in OSM tree: Under the External ServerNet Fabric (X and Y) objects.
Example: SwitchModule $ZZSMN.Y1
