Assuming 32-port 100GbE switches—a common model as of this writing—you can build a pod topology for a 200-server cluster using five leaf switches (assuming 40 servers per rack) and five spine switches, assuming an oversubscription ratio of 2:1 (two server-facing ports for every uplink port) for a total of 10 switches. |

All of the leaves also compute the area summary routes to announce to the other backbone area routers. S11, which saw the change, sends the new updates to its neighbors in the backbone area, the super-spines. This update propagates through the backbone area until all routers in the backbone area have received it. This includes leaves in other pods. We’re assuming that the spines are not summarizing in this case (see the “Route Summarization in Clos Networks” on page 105 for details on summarization). |
