A leaf spine network architecture is highly scalable and redundant. Leaf spine network deployments can have a minimum of two leaf switches and one spine switch. For small to medium clusters in a single rack, this back-end network consists of two redundant top-of-rack (ToR) switches rather than implementing a leaf-spine deployment. The backbone of this network architecture is called the spine, from which each leaf is connected to further extend network resources. The network can grow uniformly by simply adding more spine or leaf switches, and without changing the network performance. The spine section of the network grows horizontally which restricts the layers of the ...
