@dan_nanni: Data center network topologies are designed to optimize scalability, fault tolerance, and efficient data flow between servers and devices Here are well-known network topologies deployed in today’s data centers 😎👆 ✅ Three-Tier: Classic enterprise design with core, aggregation, and access layers; hierarchical and familiar. ✅ Spine-Leaf: Modern cloud layout where every leaf switch connects to every spine for predictable latency and bandwidth. ✅ Fat-Tree: Hyperscale/HPC variant with many equal-cost paths between layers to improve throughput and scalability. ✅ Dragonfly: HPC-focused topology combining local clusters (meshes) with selective high-speed global links to scale efficiently.
