Juniper QFX Series Data Center Switches
HPE Juniper Networking QFX Series: EVPN-VXLAN spine-and-leaf switching from 1GbE leaves to a 102.4 Tbps, liquid-cooled AI fabric spine.
Overview
The Juniper QFX Series is HPE Juniper Networking's family of data center switches for spine-and-leaf IP fabrics, AI/ML cluster fabrics, data center gateway and interconnect, and campus distribution and core. It is built for enterprise, federal, SLED, and healthcare teams that need one consistent Junos-based operating model from a single top-of-rack leaf to a multi-site fabric.
Every platform runs Junos OS or Junos OS Evolved with the same routing stack and EVPN-VXLAN feature set, scaling from 1GbE fixed leaves up to the QFX5250, a liquid-cooled, Ultra Ethernet Transport-ready switch delivering 102.4 Tbps on Broadcom Tomahawk 6 silicon, and the modular QFX10016 chassis at 96 Tbps. The lineup now spans the AI-focused QFX5250 and QFX5140 alongside established fixed platforms (QFX5240, QFX5230, QFX5130, QFX5120) and the QFX10008/QFX10016 modular spine and core chassis, all managed through Apstra Data Center Director for intent-based design and closed-loop assurance.
Uniqcli, an authorized HPE and HPE Juniper Networking partner, sizes, sources, and supports QFX deployments for federal, SLED, healthcare, and enterprise buyers, including TAA-compliant configurations and quoting through GPC, SAP, FAR-based orders, and GSA eBuy contract vehicles.
Why Juniper QFX Series Data Center Switches
Data center and AI fabrics live or die on consistent throughput, predictable latency, and an operating model your team can actually run at scale. The QFX family gives you one Junos-based software stack and one EVPN-VXLAN design across leaf, spine, and core, from a QFX5110 leaf to a liquid-cooled QFX5250 AI spine, so a fabric can grow from a single rack to a multi-site interconnect without re-architecting. For federal and regulated buyers, that consistency plus Apstra-driven, intent-based automation reduces operational risk and audit overhead, and we can source TAA-compliant configurations to fit your acquisition requirements.
One Junos OS across the fabric
Leaf, spine, and core platforms share the same Junos OS / Junos OS Evolved routing stack and CLI, so designs, automation, and operator skills carry across the entire QFX family, from the newest QFX5250 down to a QFX5110 leaf.
EVPN-VXLAN and IP fabric built in
Standards-based EVPN-VXLAN and a broad IP fabric capability set let you build interoperable spine-and-leaf overlays for data center, DCI, and campus fabric without proprietary lock-in.
1GbE to 1.6 Tbps ports in one family
Port options span 1/10/25/40/50/100/200/400/800GbE, with the QFX5250 offering 1.6 Tbps per port (breakable to 2x800GbE), so you can match leaf access density and spine uplink speed to the workload.
Liquid-cooled 102.4 Tbps for AI fabrics
The QFX5250 is a liquid-cooled, Ultra Ethernet Transport-ready switch on Broadcom Tomahawk 6 delivering 102.4 Tbps in 2U, purpose-built for GPU cluster training and inference fabrics.
Apstra intent-based automation
Apstra Data Center Director automates the full fabric lifecycle, design through closed-loop assurance; Juniper documents Day 2 service-provisioning time improvements of up to 20x for QFX environments running Apstra versus manual operations.
Deep-buffer and MACsec options
QFX10008/QFX10016 platforms add Q5-ASIC deep buffers (up to 100ms per port), while the QFX5120-48YM and QFX10000-30C-M line card offer MACsec AES-256 encryption for leaf-to-spine security.
What it does
Builds spine-and-leaf and super-spine IP fabrics
Fixed leaf and spine switches plus modular QFX10008/QFX10016 chassis act as universal building blocks for standards-based EVPN-VXLAN spine-and-leaf and super-spine architectures, from a single rack to a multi-pod data center.
Powers AI/ML training and inference fabrics
The QFX5250 (Broadcom Tomahawk 6, 102.4 Tbps, liquid-cooled) is built as an Ultra Ethernet Transport-ready switch for GPU-to-GPU AI fabrics, while the QFX5140 (Broadcom Trident 5, 16 Tbps) targets AI inference and border-leaf roles with RoCEv2 and dynamic load balancing.
Connects and extends data centers
QFX platforms serve as data center gateway and interconnect (DCI) nodes, including secure DCI, to connect and extend EVPN-VXLAN fabrics across multiple sites.
Carries IP storage traffic
High-density 100G/400G/800G switching supports IP storage networking, including NVMe/RoCEv2 and NVMe/TCP, to converge storage and data onto a single Ethernet fabric.
Encrypts links in flight
MACsec AES-256 on the QFX5120-48YM (all ports, 4 Tbps bidirectional) and the QFX10000-30C-M line card for QFX10008/QFX10016 spines protects data in motion for compliance-sensitive federal, healthcare, and SLED deployments, including end-to-end leaf-to-spine MACsec.
Automates Day 0 through Day 2
With Apstra Data Center Director, the fabric is designed, deployed, and continuously validated through intent-based, closed-loop assurance; Juniper documents Day 2 service-provisioning time improvements of up to 20x versus manual operations.
Absorbs bursty traffic without drops
QFX10000-series line cards run Juniper's custom Q5 ASIC with up to 100ms of deep packet buffer per port, keeping spine and core links from dropping packets during microbursts common in storage and AI workloads.
Serves campus core and distribution
QFX5120, QFX5130, and QFX5700 platforms extend beyond the data center into campus distribution, core, and multitier campus fabric roles using the same Junos software model as the rest of the family.
