QFX3500 SWITCH
Product Overview
The Juniper Networks QFX3500
Switch delivers a high-performance,
ultra low latency, feature rich Layer
2 and Layer 3 solution for the most
demanding data center environments.
Featuring standards-based Fibre
Channel I/O and iSCSI convergence
capabilities in a compact form factor,
the QFX3500 is a versatile, high
density 10GbE platform that also
delivers a fabric-ready edge solution
for the Juniper Networks QFabric
architecture.
Product Description
The high-performance Juniper Networks® QFX3500 Switch addresses a wide range of
deployment scenarios, which include traditional data centers, virtualized data centers,
high-performance computing, network-attached and iSCSI storage, FCoE convergence,
and cloud computing.
Featuring 48 dual-mode small form-factor pluggable transceiver (SFP+/SFP) ports
and four quad small form-factor pluggable plus (QSFP+) ports in a 1 U form factor, the
QFX3500 Switch delivers feature rich Layer 2 and Layer 3 connectivity to networked
devices such as rack servers, blade servers, storage systems, and other switches in highly
demanding, high-performance data center environments. For end-to-end convergence,
the QFX3500 has extensive DCB capabilities including specific iSCSI support. For FCoEbased converged server edge access environments, the QFX3500 is also a standardsbased Fibre Channel over Ethernet (FCoE) Transit Switch and FCoE to Fibre Channel
(FCoE-FC) Gateway, enabling customers to protect their investments in existing data
center aggregation and Fibre Channel storage area network (SAN) infrastructures. The
Juniper Networks QFX3500 is a highly flexible data center switch that offers several
deployment options including Fabric, Virtual Chassis and MC-LAG.
When deployed with other components of the Juniper Networks QFabric™ family, including
the QFX3100 QFabric Director and the QFX3600-I QFabric Interconnect (in a QFX3000-M
QFabric System) or QFX3008-I QFabric Interconnect (in a QFX3000-G QFabric
System), the QFX3500 delivers a fabric-ready edge solution that contributes to a highperformance, low latency, single-tier data center fabric.
By converting any 10GbE or 40GbE port into a Virtual Chassis connection, the QFX3500 can
leverage all the benefits of Juniper’s industry-leading Virtual Chassis technology including
simplified management and operations, as well as high availability. As a leaf node in
Juniper’s new Virtual Chassis Fabric architecture, the QFX3500 switch offers deterministic
rack-to-rack throughput, high availability and a smooth transition path from 1GbE to
10/40GbE. The QFX3500 can be deployed along with with Juniper QFX3600, EX4300 and
QFX5100 switches in the same Virtual Chassis and Virtual Chassis Fabric configuration.
For added configuration flexibility, up to 36 of the QFX3500’s 48 pluggable SFP+ ports
can be used in 10GbE or 1GbE mode with up to 18 of the 1GbE ports being copper. The
remaining 12 ports can be used to support 2, 4, or 8 Gbps Fibre Channel modes as well as
10GbE. Each of the four QSFP+ high speed ports can operate in 4x10GbE mode and are
capable of supporting 40 Gbps optics* in the future, providing investment protection.
