The Juniper QFX5700 and QFX5700E Switches are next‑generation, modular and fabric‑less spine‑and‑leaf switches that offer flexibility, cost efficiency with lower‑per‑bit, high‑density 400GbE, 100GbE, 50GbE, 40GbE, 25GbE, 10GbE, and 1GbE interfaces for server and intra‑fabric connectivity. A versatile, future‑proven solution for today’s data centers, the QFX5700 and QFX5700E switches support and deliver a diverse set of use cases. The line supports advanced Layer 2, Layer 3, and Ethernet VPN (EVPN)—Virtual Extensible LAN (VXLAN) features. For large public cloud providers—early adopters of servers to meet explosive workload growth‑the QFX5700 and QFX5700E switches support very large, dense, and fast 400GbE IP fabrics based on proven internet scale technology. For enterprise data center customers seeking investment protection as they transition their server farms from 1GbE to 10GbE to 25GbE, the switches also provide a high radix‑native 100GbE/400GbE EVPN‑VXLAN spine option at reduced power and a smaller footprint.
