Interconnection Solution for Juniper QFX5100 Series Switches

The data center is continuously undergoing a fundamental shift to support higher speed interfaces at the access layer. Typically, the shift is happening from 1GbE interfaces to 10GbE in the access layer. However, to support high-density 10GbE interfaces, the core and aggregation layers need to support even high-speed interfaces such as 40GbE. The juniper QFX5100 was specifically designed to solve the high port density in data centers. In this article, we will briefly introduce the Juniper QFX5100 series and offer some interconnection options for you.

Juniper QFX5100 Product Overview

The Juniper QFX5100 line of access and aggregation switches delivers low latency, flexible deployment options, making it the industry’s nimblest family of switches. Meanwhile, it lies the foundation for today’s and tomorrow’s dynamic data center. Juniper QFX5100 series is designed for the most demanding, high-performance data center deployments. Being highly flexible, it can be deployed in mixed 1GbE, 10GbE and 40GbE environments. Deployment options for QFX5100 thus can be diverse, including fabric, layer 3, and spine and leaf. So it also serves as the universal building block for data center switching architectures, enabling users to easily adapt as requirements change over time.

As a typical high density solution, each 10GbE interface of this series is tri-speed and supports 100 Mbps, 1 GbE, or 10 GbE. In addition, each interface can support either copper or fiber connectivity. And higher interface speeds such as 40 GbE can be broken out into four 10GbE interface by using a breakout cable.

Juniper QFX5100 Highlights and Switch Modules

The Juniper QFX5100 family brings a lot of new features when it comes to solving data center challenges. You can integrate the Juniper QFX5100 into many different types of architectures such as high-frequency trading, campus and enterprise. It is embracing all of the change that’s happening and providing clear and distinctive solution.

QFX5100 Switch Modules

The QFX5100 line includes four compact 1 U models and one 2 U model, each providing wire-speed packet performance and very low latency. Here, we only introduce the three most used ones: QFX5100-48S, QFX5100-24Q and QFX5100-96S.

QFX5100-48S: Compact 1 U 10GbE data center access switch with 48 small form-factor pluggable and pluggable plus (SFP/ SFP+) transceiver ports and six quad SFP+ (QSFP+) ports with an aggregate throughput of 1.44 Tbps or 1.08 Bpps per switch.

QFX5100-24Q: Compact 1 U high-density 40GbE data center access and aggregation switch starting at a base density of 24 QSFP+ ports with the option to scale to 32 QSFP+ ports with two four-port expansion modules. All 32 ports support wire-speed performance with an aggregate throughput of 2.56 Tbps or 1.44 Bpps per switch.

QFX5100-96S: Compact 2 U high-density 10GbE aggregation switch with 96 SFP+/SFP and eight QSFP+ ports with an aggregate throughput of 2.56 Tbps or 1.44 Bpps per switch.

For added flexibility, the 40GbE ports on all QFX5100 switches can be used as 4x10GbE ports using QSFP+ to SFP+ direct attach copper (DAC) or QSFP+ to SFP+ fiber splitter cables and optics. With splitter cables, the QFX5100-48S supports up to 72 10GbE ports, while the QFX5100-24Q and QFX5100-96S support up to 104 10GbE ports.

Optic and Transceiver Options for Juniper QFX5100

Juniper QFX5100 series switches can be employed in 1GbE, 10GbE and 40GbE environments owing to their high reliability and flexibility. Those 1/10/40 Gigabit Ethernet ports can support SFP, SFP+ and QSFP+ transceiver modules, as well as QSFP+ to SFP+ direct attach cable (DAC). Detailed connectivity and cabling options for Juniper QFX5100 are listed in following diagrams.
