Juniper QFX5210-64C Ethernet Switch

? The QFX5120 delivers low-latency, native 25GbE, rich Layer 2 and Layer 3 features, VXLAN overlay support, and 100GbE uplinks, making it the ideal switch for access and top-of-rack deployments.

Featuring Layer 3 gateway capabilities for bridging between virtualized and bare-metal servers, the QFX5120 is designed for extremely agile data centers that demand support for overlay/ underlay network architectures. The high-density 10GbE, 25GbE, 40GbE, and 100GbE ports also make the QFX5120 ideally suited for deployment as leaf-and-spine and leaf topologies.

Product Description

Data centers are expanding rapidly as they adopt more cloud services, creating a need for higher network bandwidth per rack. As a result, 25GbE and 100GbE have become the dominant port speeds in most data centers. The tremendous growth of 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 ® QFX5120 Ethernet Switch fits the bill, providing the foundation for dynamic data centers. Native 25GbE ports and 100GbE uplinks satisfy growing demand for 100GbE spine ports to support all server access speeds, including 10GbE and 25GbE. The QFX5120 also supports a diverse set of switching architectures, including data center fabric, Layer 3, and spine-and-leaf deployments, enabling users to easily adapt and evolve as requirements change over time.

Architecture and Key Components

The QFX5120 includes native 25GbE (fiber only) and 40GbE or 100GbE fixed-configuration options with rich L2, L3, Ethernet VPN (EVPN), and MPLS features. The QFX5120 runs the same reliable, high-performance Juniper Networks Junos ® operating system used by all Juniper Networks QFX Series Switches and EX Series Ethernet Switches, SRX Series Services Gateways, and Juniper Networks routers, ensuring a consistent control plane feature implementation and user experience across the entire Juniper infrastructure.

Product Options

The QFX5120 switch is a compact, 1 U platform that provides 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 QFX5120 control plane is enhanced with a powerful 2.2 GHz quad-core Intel CPU with 16 GB of memory and 64 GB SSD storage.

As the first member of the QFX5120 line, the QFX5120-48Y is a 25GbE/100GbE data center access switch offering 48 small form-factor pluggable plus (SFP+) transceiver ports and eight quad SFP (QSFP28) ports that can be configured as 8x40GbE or 8x100GbE ports, with an aggregate throughput of 2 Tbps or 2 Bpps per switch. For added flexibility, each QSFP28 port can also be configured as 4x25GbE ports using breakout cables, while each QSFP+ port can be configured as 4x10GbE ports using breakout cables, increasing the number of supported 25GbE and 10GbE ports per switch to 80.
