Q2F21A Use Case
Spine-Leaf Data Center Aggregation with HPE SN2700M 100GbE Switch
In a hyperscale e-commerce data center, architects deploy the HPE Q2F21A-SN2700M 100GbE 32QSFP28 Power-to-Connector airflow switch as a spine node in a leaf-spine topology. This configuration delivers sub-500ns latency, non-blocking 6.4Tbps throughput and seamless east-west traffic handling. Benefit: Scalable high-density switching reduces switch count by 30%, accelerates microservices performance and cuts operational costs by 20%.
High-Performance Computing Cluster Interconnect for AI/ML Workloads
A research institute integrates the HPE SN2700M to link GPU-intensive compute nodes in an HPC cluster for AI model training. Leveraging 32 QSFP28 ports, the switch ensures line-rate 100GbE aggregation with consistent bandwidth and low jitter across distributed parallel jobs. Benefit: Streamlined data transfer reduces AI/ML training time by up to 40% and the front-to-back airflow design simplifies hot-aisle/cold-aisle management in dense racks.
5G Edge and Multi-Access Edge Computing Deployment
A telecom operator uses the HPE Q2F21A-SN2700M at regional edge PoPs to aggregate 5G base station traffic and host latency-sensitive MEC applications. Its 1RU footprint and 32 QSFP28 100GbE ports support fronthaul/backhaul split architectures with resilient power-to-connector delivery. Benefit: High-bandwidth, sub-1ms transport elevates subscriber QoE for AR/VR and real-time analytics while reducing power consumption by 25% over legacy 40GbE switches.
