QFX5100-24Q-3AFI Use Case
Spine-Leaf Data Center Interconnect for Hyperscale Cloud
In a hyperscale enterprise cloud environment, the QFX5100-24Q-3AFI serves as a spine switch in a leaf-spine topology, aggregating 48 leaf switches over 24 QSFP+ 40 GbE ports and offering two 100 GbE uplinks via expansion slots. Redundant fans and dual AC power supplies ensure five-9s availability, while back-to-front airflow aligns with hot-aisle/cold-aisle practices. Outcome: sub-2 µs latency, linear scaling to 10 K+ servers, and carrier-grade uptime for mission-critical applications.
Ultra-Low-Latency Fabric for High-Frequency Trading
At a financial exchange colocation, trading firms deploy the QFX5100-24Q-3AFI as an aggregation switch to connect trading servers and market data feeds. With wire-speed 40 GbE switching on 24 QSFP+ ports, two 100 GbE expansion uplinks, and hardware-accelerated forwarding, firms achieve deterministic sub-microsecond latency. Redundant fans and power supplies guarantee continuous operation, and back-to-front airflow matches exchange rack standards. Outcome: maximum order throughput, minimized slippage, and uncompromised trading resilience.
5G Mobile Edge Aggregation for Service Providers
A tier-1 telecom operator uses the QFX5100-24Q-3AFI at its 5G mobile edge to aggregate cell-site traffic. The switch’s 24 QSFP+ ports provide 40 GbE backhaul to macro and small cells, while two 100 GbE expansion slots connect to the regional core. Redundant cooling and power modules deliver SLA-driven reliability, and back-to-front airflow integrates seamlessly into edge racks. Outcome: scalable high-bandwidth aggregation, simplified network growth, and 99.99% service availability for latency-sensitive 5G workloads.
