48X25G+8X100G TAA 1U AC AIRFLOW OUT

The QFX5120 Switch delivers low latency, rich Layer 2 and Layer 3 features, and advanced EVPNVXLAN capabilities, making it an ideal data center top-of-rack and aggregation switch for enterprise multicloud deployments.

Featuring Layer 3 gateway capabilities for routing between virtualized and bare-metal servers, the QFX5120 is designed for extremely agile data centers that require support for overlay/ underlay network architectures. Native 25GbE with 100GbE uplink ports on the QFX5120- 48Y, combined with 32 ports of 100GbE on the QFX5120- 32C, make the QFX5120 family ideal for leaf-and-spine network deployments.

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 Switch fits the bill, providing the foundation for dynamic data centers. Native 25GbE ports on the QFX5120- 48Y satisfy the growing demand for server access speeds, while high-density 100GbE ports on the QFX5120-32C satisfy the need for compact, lower power devices in the spine. The QFX5120 is packed with software features that support traditional fabric designs with multichassis link aggregation (MC-LAG) or evolving SDN architectures with Ethernet VPN (EVPN)/Virtual Extensible LAN (VXLAN) on IP fabric underlays.

Architecture and Key Components

The QFX5120 includes native 25GbE (fiber only) and 100GbE fixed-configuration options with rich L2, L3, EVPN, and MPLS features. The QFX5120 runs the same reliable, high-performance Juniper Networks Junos® operating system used by all Juniper Networks QFX Series 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 family includes two compact, 1 U platforms that provide wirespeed packet performance, very low latency, and a rich set of Junos OS features.

• 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.
• The QFX5120-32C is a compact 100GbE data center spine switch offering 32 QSFP28 or 32 quad SFP+ (QSFP+) ports. The 100GbE ports can also be configured as 4x25GbE ports using breakout cables, enabling the QFX5120- 32C to be used as a high-density 25GbE top-of-rack switch.

In addition to a high-throughput Packet Forwarding Engine (PFE), the performance of the QFX5120 control plane is enhanced by a powerful 2.2 GHz quad-core Intel CPU with 16 GB of memory and 64 GB SSD storage.
