B1-Q5110-48SO-A-A5

Product overview

QFX5110 access and aggregation switches deliver low latency, rich Layer 2 and Layer 3 features, VXLAN overlay deployments, and 100GbE uplinks.

The QFX5110 features:

• L3 gateway capabilities for bridging between virtualized and bare-metal servers


• Rich Layer 2, Layer 3, and MPLS support


• High-density 10GbE, 40GbE, and 100GbE ports for data center spine and leaf topologies and campus distribution

Product description

Data centers are rapidly adopting cloud services, whether completely off-premises models or hybrid models with critical services offered through on-premises private clouds. The tremendous growth of off-premises 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 provide 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. The QFX5110 switch can be positioned in campus distribution and core deployments.

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 Junos operating system used by the Juniper Networks QFX5100 family of products and EX Series Ethernet Switches, ensuring a consistent implementation and operation of control plane features.

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 high throughput 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.
