Overview

The QFX3500 is a high-performance, low-latency, feature-rich Layer 2 and Layer 3 switch optimized for virtualized data center deployments. It can be used in seamless Juniper 1/10/40GbE architectures such as Virtual Chassis, Virtual Chassis Fabric, and QFabric deployments, as well as in open architectures such as Spine and Leaf and Layer 3.

The QFX3500 10GbE switch has 63 dual-mode, small form-factor pluggable transceiver (SFP+/SFP) ports, and four quad small form-factor pluggable plus (QSFP+) ports that deliver feature-rich Layer 2 and Layer 3 connectivity to high-performance networked data center devices.

The QFX3500 is also a standards-based Fibre Channel over Ethernet (FCoE) transit switch and FCoE-to-Fibre Channel (FCoE-FC) gateway that protects customer investments in existing data center aggregation and Fibre Channel storage area network (SAN) infrastructures.

Features

  • Throughput and capacity up to 2.56 Tbps and 1.44 Bpps, respectively, sustain wire-speed switching with low latency and jitter, as well as full Layer 2 and Layer 3 performance.
  • Redundant power and cooling ensure high availability.
  • Separate control and data planes ensure maximum system availability.
  • Server and network virtualization support using large media access control (MAC) tables enables large-scale virtualization deployment in VMware with Juniper Contrail for select models, and Junos Space Network Director for combined networks.
  • Energy efficiency provides green solutions that lower operational expenses.

The Network Driving Economic Growth in Ohio

The OneCommunity Case Study

Breaking Down Geographic Barriers to Provide Better Healthcare to Citizens of Northeast Ohio

The performance and low latency of the SRX3500 Switch make it ideal for supporting MRI and other healthcare applications hosted in OneCommunity's data center. With QFX3500, OneCommunity can start small and, like the Virtual Chassis technology, expand incrementally as demand grows.

Read the case study

OneCommunity uses the QFX3500 with

  • MX960

    MX960 performs at 9.92 Tbps for cloud and large enterprise data centers, service provider edge networks, and cable operator hubs.

  • EX4500

    The EX4500 is a compact, high-performance platform for data center, campus, and service provider deployments.
