SummitStack nodes should be connected to each other in a ring topology. In a ring topology, one link is used to connect to a node and the other link is used to connect to another node. The result forms a physical ring connection. This topology is highly recommended for normal operation.
The following figure represents a maximal ring topology of eight active nodes.
The following figure shows what the same ring topology would look in actual practice. Each switch in the rack is connected to the switch above it and the switch below it. To complete the ring, a longer cable connects Switch 1 with Switch 8.
Note that, while a physical ring connection may be present, a ring active topology exists only when all nodes in the stack are active nodes.
