Product Overview
The Juniper Networks QFX5100 line
of access and aggregation switches
delivers low latency, flexible
deployment options, and rich Layer
2 and Layer 3 features, making it
the industry’s most nimble family
of switches.
Featuring Topology-Independent
In-Service Software Upgrades
(TISSU
*
) and support for L2
gateway capabilities for bridging
between virtualized and bare-
metal servers, the QFX5100
is designed for the most
demanding, high-performance
data center deployments. Highly
flexible, the QFX5100 can be
deployed in mixed 1GbE, 10GbE,
and 40GbE environments within
Juniper Virtual Chassis, Virtual
Chassis Fabric, Junos Fusion
and QFabric architectures, as
well as within industry-standard
architectures such as spine and
leaf and Layer 3 fabrics.
Product Description
The highly flexible, high-performance Juniper Networks
®
QFX5100 line of Ethernet
switches provides the foundation for today’s and tomorrow’s dynamic data center. As
a critical enabler for IT transformation, the data center network supports cloud and
software-defined networking (SDN) adoption, as well as rapid deployment and delivery
of applications. Mission-critical applications, network virtualization, and integrated or
scale-out storage are driving the need for more adaptable networks. With its diverse set
of deployment options, including fabric, Layer 3, and spine and leaf, the QFX5100 is the
universal building block for data center switching architectures, enabling users to easily
adapt as requirements change over time.
The QFX5100 line includes 10GbE (fiber and copper) and 40GbE fixed-configuration options
with rich Layer 2, Layer 3, and MPLS features. The QFX5100 runs the same reliable, high-
performance Juniper Networks Junos
®
operating system that is used by Juniper Networks
QFabric
®
family of products, EX Series Ethernet Switches, Juniper Networks routers, and
Juniper Networks SRX Series Services Gateways, ensuring a consistent implementation and
operation of control plane features across the entire Juniper infrastructure.
Featuring a built-in Insight Technology capability, the QFX5100 provides valuable
performance and troubleshooting data via microburst monitoring and hotspot statistics.
The QFX5100 can also be used as a high-performance QFabric Node in Juniper’s high-
scale QFabric System or as a Satellite device in a Junos Fusion fabric architecture, deployed
in Juniper’s new Virtual Chassis Fabric switching architecture, and installed in Juniper’s
existing Virtual Chassis switching architecture.
