Description:
The Juniper QFX5100 Series is a family of high‑performance data center switches built for top‑of‑rack (ToR), leaf/spine, and aggregation layers in modern data center fabrics. They deliver low‑latency, high‑throughput Layer 2 and Layer 3 switching, making them ideal for performance‑sensitive environments such as cloud deployments, virtualization, and distributed applications. The QFX5100 supports industry‑standard architectures like spine‑and‑leaf and EVPN‑VXLAN fabrics and includes automation and orchestration capabilities for simplified deployment and operation.
