Additionally, the open architecture ensures that customers can innovate on top of Juniper Networks Junos ® operating system to accelerate the pace of innovation. The QFX10000 line also supports Junos Fusion, a simple, easy-to-deploy fabric that scales to support mid-to-large data center deployments while simplifying network management and configuration.

The QFX10000 is also a key component of Juniper Networks MetaFabric TM Architecture, which provides a simple, open and smart approach to building data center networks. Additionally, the QFX10000 supports Data Center Interconnect (DCI), critical to workload mobility and application availability.

For networks evolving to SDN, the QFX10000 integrates with VMware NSX SDN controllers and can act as a Virtual Extensible LAN (VXLAN) Layer 2 and Layer 3 gateway. The open and standards-based QFX10000 switches also interoperate with the Open vSwitch Database (OVSDB) to support automated management and control capabilities. The QFX10000 line integrates with OpenContrail SDN controller to allow users to choose their preferred SDN systems.

Two QFX10000 modular chassis options are available, providing full deployment flexibility:

• QFX10008 Ethernet Switch, an 8-slot, 13 U chassis that supports up to eight line cards
• QFX10016 Ethernet Switch, a 16-slot, 21 U chassis that supports up to 16 line cards

Both QFX10000 modular chassis can accommodate any combination of the following QFX10000 Ethernet line cards:

• QFX10000-36Q, a 36-port 40GbE quad small form-factor pluggable plus transceiver (QSFP+) or 12-port 100GbE QSFP28 line card
• QFX10000-30C, a 30-port 100GbE QSFP28/40GbE QSFP+ line card
• QFX10000-60S-6Q, a 60-port 1GbE/10GbE SFP/SFP+ line card with six-port 40GbE QSFP+ / two-port 100GbE QSFP28

Fully configured, a single QFX10016 chassis can support up to 480 100GbE ports, delivering the industry's highest line-rate 100GbE port densities in its class. The QFX10000 switch fabric is capable of delivering up to 7.2 Tbps (full duplex) per slot, and the midplane-less orthogonal interconnect architecture ensures system longevity.

QFX5110 access and aggregation switches deliver low latency, rich Layer 2 and Layer 3 features, VXLAN overlay deployments, and 100GbE uplinks, making it the industry's most nimble line of switches. Featuring L3 gateway capabilities for bridging between virtualized and bare-metal servers, the QFX5110 is designed for extremely agile data centers that demand support for overlay/underlay network architectures. The highdensity 10GbE, 40GbE, and 100GbE ports also make the QFX5110 ideally suited for use in spine and leaf topologies.

Product Description

Data centers are rapidly adopting cloud services, whether completely off-premise models or hybrid models with critical services offered through on-premise private clouds. The tremendous growth of off-premise cloud services, coupled with the widespread adoption of overlay technologies, has created a need for highly agile switching platforms that can satisfy the demands of these evolving data centers. The high-performance Juniper Networks® QFX5110 line of Ethernet switches fit the bill, providing the foundation for dynamic data centers. As a critical enabler for IT transformation, the data center network supports cloud and SDN adoption, network virtualization, integrated/scale-out storage, and the rapid deployment and delivery of mission-critical applications that significantly increase east-west traffic within the data center. Furthermore, increasing demand for 100GbE spine ports is driving the need for 100GbE uplinks for all server access speeds, including 10GbE and 40GbE. The QFX5110 includes 100GbE uplinks, enabling it to support a diverse set of switching architectures, including fabric, Layer 3, and spine-and-leaf deployments, enabling users to easily adapt as requirements change over time.

Architecture and Key Components

The QFX5110 switches include 10GbE (fiber) and 40GbE or 100GbE fixed-configuration options with rich Layer 2, Layer 3, and MPLS features. The QFX5110 switches run the same reliable, high-performance Juniper Networks Junos® operating system that is used by the Juniper Networks QFX5100 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.

QFX5110 Switch Models

The QFX5110 switches are compact, 1 U platforms that provide wire-speed packet performance, very low latency, and a rich set of Junos OS features. In addition to a highthroughput Packet Forwarding Engine (PFE), the performance of the QFX5110 control plane is further enhanced with a powerful 1.8 GHz quad-core Intel CPU with 16 GB of memory and 64 GB SSD storage.

Two QFX5110 switch models are available:

• QFX5110-48S-A 10GbE/100GbE data center access switch, the QFX5110-48S offers 48 small form-factor pluggable plus (SFP+) transceiver ports and four QSFP28 ports that can be configured as 4x40GbE or 4x100GbE ports, with an aggregate throughput of 1.76 Tbps or 1.32 Bpps per switch. For added flexibility, each QSFP28 port can also be configured as 4x10GbE ports using breakout cables, increasing the total number of supported 10GbE ports to 64 per switch.
