Description
The Juniper QFX5120-48T-AFO-T is a high-performance, fixed-configuration switch designed for data center top-of-rack (ToR) or spine deployments. It provides a dense port configuration with 48 10GbE RJ45 ports, ideal for connecting servers, storage arrays, and other high-density endpoints. The switch's ability to support 10GbE speeds ensures high throughput for demanding applications and workloads. For network aggregation and scalability, the QFX5120-48T-AFO-T is equipped with six 40GbE QSFP+ uplink ports. These high-bandwidth ports allow for efficient aggregation of traffic from multiple access switches or direct connection to spine switches in a data center fabric. The combination of 10GbE access and 40GbE uplinks provides a balanced architecture for modern data center networks, minimizing bottlenecks and maximizing performance. Running on Juniper's Junos OS, this switch offers advanced Layer 2 and Layer 3 features, including support for EVPN-VXLAN, BGP, OSPF, and other routing protocols essential for data center networking. Its low latency (< 1 microsecond) is critical for performance-sensitive applications like high-frequency trading or real-time analytics. The AFO designation indicates front-to-back airflow, a common requirement in data center rack deployments, and the redundant power supplies ensure high availability.
