- Data Center Network Health Score CalculatorScore a data centre fabric out of 100 on utilisation, oversubscription, availability and drop rate.
- DC Gateway Capacity CalculatorCount the border gateways a data centre needs based on throughput, NAT session scale and redundancy.
- DCI Bandwidth CalculatorSize a data centre interconnect from daily change rate, replication window, RPO and distance latency.
- East-West Traffic CalculatorEstimate server-to-server traffic inside a data centre and how much of it actually crosses the fabric.
- EVPN Route CalculatorEstimate EVPN route-type counts and control-plane memory from VTEPs, MAC addresses, VNIs and prefixes.
- Fabric Bandwidth CalculatorTotal spine capacity, bisection bandwidth and per-leaf share for a data centre fabric.
- Fabric Expansion CalculatorCheck whether new leaves fit the existing spines, and count the spine ports, cables and bandwidth they add.
