Juniper Networks QFX5100 and QFX5110

High-performance, agile, and scalable 10/25/40/100GbE data center switches.

The QFX5100 Series are access and top-of-rack 10/25/40/100GbE Layer 2 and Layer 3 switches designed with a powerful feature set for application delivery and virtualized data centers. These switches enable high-availability data center operations by allowing unified in-service software upgrades (ISSU). As cloud trends continue to push the boundaries of network performance, the QFX5100 switches are optimized for high performance, density, and multicloud scale.

QFX5100 switches provide universal building blocks for multiple fabric architectures, including mixed 1/10/40/100GbE Virtual Chassis, Virtual Chassis Fabric, and Junos Fusion architectures. The switches also support open architectures, such as spine-and-leaf deployments, Layer 3, and OpenClos IP fabrics.

Juniper QFX5100

To meet today’s business demands, both software and hardware must work together as part of a unified network. QFX5100 switches provide the leaf or access layer foundation of the underlying data center infrastructure for Contrail Networking, a software platform that uses mature standards and protocols such as BGP EVPN and VXLAN to automate the setup and life-cycle management of QFX switches. This approach enables Contrail Networking to provide end-to-end policy and control across physical and virtual environments in the multicloud.

QFX5100 Features

High-Performance Throughput

Throughput of up to 2.56 Tbps sustains wire-speed switching with low latency and jitter, as well as full Layer 2 and Layer 3 performance.

Redundant Power and Cooling

Dual hot-swappable AC or DC power supplies provide 1+1 redundancy, while five hot-swappable fan trays maintain high system availability.

Separate Control and Data Planes

Keeping the control and data planes independent maximizes system availability and throughput.

Server and Network Virtualization

A software-programmable infrastructure lets you make the most of your network resources and quickly adapt to changing needs.

Energy Efficiency

Minimized power consumption reduces your carbon footprint and operational expenses.

Network Automation

Support for Python, Puppet, and zero-touch provisioning (ZTP) helps you address growing network complexity.

Unified In-Service Software Upgrades (ISSU)

Network administrators make software upgrades in minutes with no downtime, which means no lost user productivity.
