Leaf-and-Spine Fabric Architectures | Ivan Pepelnjak

Every major networking vendor is busy promoting its own (usually proprietary) Data Center Fabric. While they're debating the architectures and proprietary nature of competitors' offerings, and solving dubious problems like large-scale bridging with pre-standard implementations, the data center users still face the problem succinctly expressed by James Hamilton: "Data Center Networks are in my Way".

It turns out we don't need rocket-science data center fabric solutions to solve that problem - it's possible to build large all-point-equidistant networks with no constraints on workload placement with existing gear from numerous vendors using decades-old Clos architectures.

The Leaf-and-Spine Fabric Architectures webinar describes the Clos architecture concepts used to build leaf-and-spine architectures, and single- and multistage designs that can be used to build large layer-2 or layer-3 all-point-equidistant Data Center networks.
