WebA 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.
