The Juniper Networks QFX5220 Switch is a next-generation, fixed-configuration spine-and-leaf switch. It offers flexible, cost-effective, high-density 400GbE, 200GbE, 100GbE, 50GbE, 40GbE, 25GbE, and 10GbE interfaces for server and intra-fabric connectivity, and delivers a versatile, future-proofed solution for today’s data centers.

QFX5220 switches support advanced Layer 2, Layer 3, and MPLS features. For large public cloud providers—early adopters of high-performance servers to meet explosive workload growth—the QFX5220 supports very large, dense, and fast 400GbE IP fabrics based on proven internet-scale technology. For enterprise customers seeking investment protection as they transition their server farms from 10GbE to 25GbE, the QFX5220 switch also provides a high radix-native 100GbE lean-spine option at reduced power and a smaller footprint.

Two QFX5220 models are available, supporting different configurations and use cases. Delivering 25.6 Tbps (bidirectional) of bandwidth, both models are optimally designed for spine‑and‑leaf deployments in enterprise, HPC, service provider, and cloud data centers.

QFX5220-32CD: The QFX5220‑32CD offers 32 ports in a low‑profile 1 U form factor. High‑speed ports support a wide variety of port configurations, including 400GbE, 200GbE, 100GbE, 50GbE, 40GbE, 25GbE, and 10GbE. The QFX5220‑32CD is equipped with two AC or DC power supplies, providing 1+1 redundancy when all power supplies are present, and six hot‑swappable fans offering ports‑to‑FRUs (AFO) or FRUs‑to‑ports (AFI) airflow options, providing (5+1) redundancy.

QFX5220-128C: The QFX5220‑128C offers 128 ports in a 4 U form factor. The high‑speed ports support a variety of configurations, including 100GbE,40GbE, 25GbE, and 10GbE. The switch is equipped with four AC or DC power supplies, providing 2+2 redundancy when all power supplies are present, and six hot‑swappable ports‑to‑FRUs (AFO) airflow fans, providing (5+1) redundancy.

Both QFX5220 switch models include an Intel processor to drive the control plane, which runs the Juniper Networks Junos OS Evolved operating system software.
