ServerNet Cluster Description

Three Network Topologies Supported
Split-Star Topology
The split-star topology, introduced with the G06.12 RVU, supports from 2 to 16 nodes
and uses up to four cluster switches—two for the X fabric and two for the Y fabric.
The two cluster switches on each fabric can have a position ID of either 1 or 2.
Consequently, the cluster switches on the X fabric are named X1 and X2, and the
cluster switches on the Y fabric are named Y1 and Y2.
The first cluster switch on a fabric (X1 or Y1) supports ServerNet nodes 1 through 8.
The second cluster switch on the same fabric (X2 or Y2) supports ServerNet nodes 9
through 16.
Figure 1-3 shows both fabrics of a 16-node ServerNet cluster connected in a split-star
topology.
