S4048 3 Years * 4h Use Case

High-Density Top-of-Rack Aggregation for Hybrid Cloud Data Centers

In a multinational financial services firm’s hybrid cloud environment, the Dell Networking S4048-ON delivers high-density top-of-rack aggregation with 48×10GbE SFP+ and 6×40GbE QSFP+ ports, ensuring sub-2μs latency for east-west traffic. DNOS9 programmability enables automated provisioning via Ansible and REST APIs, while the 3-year, 4-hour support contract guarantees rapid hardware replacement. Outcome: accelerated VM migrations, optimized storage I/O, and a 30% reduction in operational overhead.

Low-Latency Interconnect for High-Performance Computing Clusters

In an academic research campus’s HPC deployment, the S4048-ON switch provides ultra-low-latency, lossless connectivity between compute nodes and parallel file systems using 40GbE QSFP+ uplinks and 10GbE SFP+ leaf ports. Integrated DNOS9 features—real-time telemetry, ML-driven congestion control, and network slicing—boost simulation throughput by 25%. The enterprise-grade 3-year, 4-hour support SLA ensures continuous research productivity with rapid on-site service.

Scalable Campus Core Switching for Enterprise Digital Transformation

For a global manufacturing enterprise, the Dell Networking S4048-ON acts as a scalable campus core, aggregating multiple building distribution switches over 40GbE links. Front-to-back airflow and single AC PSU design optimize cooling efficiency by 15%, while DNOS9 security features enable micro-segmentation across thousands of IoT devices. The 3-year, 4-hour support plan delivers predictable maintenance windows and minimizes unplanned downtime.
