Delivering an impressive throughput of up to 2.56 Tbps, the QFX5120 Switches ensure seamless wire-speed switching, characterized by minimal latency and jitter, and comprehensive Layer 2 and Layer 3 performance.
Redundant Power and Cooling
Ensuring robust system reliability, these switches incorporate dual hot-swappable AC or DC power supplies, providing a resilient 1+1 redundancy. Additionally, the presence of five hot-swappable fan trays contributes to maintaining high system availability.
Advanced Capabilities in Junos OS
Equipped with advanced networking features embedded in the Junos OS, the QFX5120 Switches support protocols such as Border Gateway Protocol (BGP), Multiprotocol Label Switching (MPLS), and Fibre Channel over Ethernet (FCoE).
Leveraging Juniper’s Apstra solution, these switches provide complete Day 0/1/2 capabilities for IP/EVPN fabrics, offering sophisticated fabric management solutions.
Server and Network Virtualization
The QFX5120 Switches incorporate a software-programmable infrastructure, enabling efficient utilization of network resources and swift adaptation to changing operational needs.
Addressing the increasing complexity of modern networks, these switches support Python, Puppet, and Zero Touch Provisioning (ZTP), facilitating advanced network automation.
Flexible Deployment Options
Featuring EVPN/VXLAN Layer 2 and Layer 3 gateway support for both edge-routed and centrally-routed overlay data center deployments, the QFX5120 Switches offer versatile deployment options.
Designed for data centers and campus deployments, the QFX5120 Switches offer a fixed configuration of 1 U, supporting 1/10/25/40/100GbE. With the growing demand for higher network bandwidth per rack in cloud services, these switches strategically support dominant port speeds of 10GbE, 25GbE, and 100GbE.
Incorporating advanced features suitable for both traditional fabric designs with multichassis link aggregation (MC-LAG) and evolving SDN architectures with Ethernet VPN (EVPN)/Virtual Extensible (VXLAN) on IP fabric underlays, the QFX5120 Switches stand as a robust infrastructure foundation for evolving business and network requirements. Juniper’s Apstra solution further enhances these switches by providing a comprehensive fabric management solution, driven by intent-based automation for deployment and robust monitoring for assured operation.
The QFX5120 is ideal for data center and campus deployments and comes in four models:
