Spine-leaf design for data centers

“

(soft music) - [Instructor] In this video, we want to talk about a network topology that we often see in today's data centers. And we know that in an enterprise network we might have a three-tier design or we might have a collapsed core design. But let's think about the data center for a moment. In the data center, we typically have a Spine-Leaf design or some literature, we'll call that a leaf spine topology. Here's how I want you to think about this. Imagine that in a data center we've got all these cabinets, and these cabinets might be filled with different servers. Well, in many data center designs in the top of those racks, we have a couple of switches for redundancy. And since they live at the top of the rack and the servers are plugging into the switches, oftentimes those are called Top-of-Tack or ToR Switches because they're physically located at the top of the rack. And these Top-of-Rack switches, they can act as leaves in this spine and leaf topology. And the ports on that…
