Example: Merging Two Star Topologies to Create a
Split-Star Topology
Figure 4-5 shows the merging of two three-node ServerNet clusters into a split-star
topology that can support up to 16 nodes. The cluster switches for one of the three-
node clusters are reconfigured as X2 and Y2 in order to construct the new topology. In
addition, the merged cluster uses 1-kilometer four-lane links. Therefore, all nodes must
run G06.11 or a later G-series RVU.

G06.09, G06.10, or G06.11 If the four-lane link is less
than 80 meters, the cluster
can contain G06.09, G06.10,
G06.11, or G06.12 nodes.
If the four-lane link is more
than 80 meters, G06.11 or a
later G-series RVU is
required on all nodes.
