Juniper QFX5110-48S-AFO 48-SFP+ 10GbE 4-QSFP28 100GbE Switch
The Juniper QFX5110-48S-AFO is a high-performance data center leaf switch featuring 48x10GbE SFP+ access ports and 4x100GbE QSFP28 uplink ports in a 1U form factor with front-to-back (AFO) airflow. The 48 SFP+ ports provide 10GbE fiber connectivity for server access in top-of-rack deployments, while the 4 QSFP28 100GbE uplink ports provide high-bandwidth connections to 100GbE spine switches in modern high-speed data center fabric architectures.
The 100GbE QSFP28 uplinks represent a significant bandwidth upgrade over 40GbE uplinks, providing 2.5x more uplink bandwidth per port to the spine layer. This higher uplink capacity addresses the bandwidth demands of modern server infrastructure equipped with 10GbE or 25GbE server NICs generating high east-west traffic volumes within the data center fabric. QSFP28 100GbE also supports breakout to 4x25GbE for flexible connectivity options.
The QFX5110-48S supports EVPN-VXLAN for leaf-spine fabric overlay networking, enabling scalable multi-tenant data center network designs with hardware VTEP (VXLAN Tunnel Endpoint) for efficient tunnel processing. Junos OS provides comprehensive data center networking capabilities, including BGP, OSPF, ECMP, MC-LAG, BFD for fast failure detection, and advanced Quality of Service, making the QFX5110 suitable for demanding enterprise and cloud provider data center leaf deployments.
