What this tool does

The Data Center Designer visualizes network topologies based on user-defined parameters. It generates logical diagrams for Leaf-Spine or 3-Tier architectures and calculates a basic Bill of Materials (BOM) including switch counts and transceiver estimates.

When engineers use this

  • Planning logical topologies and cabling requirements for data center deployments.
  • Estimating hardware quantities (switches, optics) for budget proposals.
  • Visualizing connections between Core, Spine, and Leaf layers.

How to interpret the results

  • Nodes: Represent network devices (e.g., Spines, Leafs).
  • Edges: Represent physical links between devices.
