Red Hat OpenStack Platform has a composable network architecture that you can use to adapt your networking to the routed spine-leaf data center topology. In a practical application of routed spine-leaf, a leaf is represented as a composable Compute or Storage role usually in a data center rack, as shown in Figure 1.1, "Routed spine-leaf example". Sep 28, 2023 · The spine-leaf architecture establishes a robust connection between servers and the core network, offering greater flexibility in hyper-scale data centers. By deploying the leaf switch as a bridge between servers and the core network, each leaf switch connects to all spine switches, forming a sizable non-blocking fabric.

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.
