S4148T-ON Use Case
Data Center Leaf Switch for High-Performance Compute Clusters
In a mid-sized cloud service provider environment experiencing exponential growth in virtualized workloads, IT teams deployed the Dell Networking S4148T-ON (1U, 48x10Gbase-T, 4x25GbE Q28, 2xQSFP+, dual PSU) running OS10 as leaf switches in a spine-leaf fabric. By leveraging its high-density 10GbE server connectivity and 25GbE uplinks, the S4148T-ON delivers sub-microsecond latency and non-blocking throughput for HPC and AI/ML training clusters. The result is a 40% reduction in north-south latency, seamless network scaling to 1,024 servers, and a 30% reduction in power and rack-space footprint compared to legacy 1GbE/10GbE switches.
Campus Network Aggregation and Secure Branch Connectivity
A multinational enterprise with distributed regional offices needed a resilient, high-capacity aggregation layer to consolidate 10GbE campus distribution switches and secure SD-WAN tunnels. Deploying the S4148T-ON (1U, 48x10Gbase-T) at each PoP enabled 48 simultaneous 10GbE edge links to access switches, plus 4x25GbE Q28 and 2x40GbE QSFP+ uplinks into the corporate core. OS10’s native EVPN-VXLAN overlays and automated policy enforcement provided zero-touch provisioning and micro-segmentation, resulting in a 60% faster branch rollout, 99.999% network availability, and a 25% reduction in operational overhead.
Hybrid Cloud Gateway with Automated Fabric Management
A financial services firm required deterministic connectivity between its on-premises datacenter and multiple hyperscale cloud regions for real-time trading data. By positioning the Dell Networking S4148T-ON (48x10Gbase-T, 4xQ28, 2xQSFP+) as the hybrid cloud gateway, they established high-bandwidth 10GbE links to on-prem servers and 40GbE uplinks to cloud-on-ramp routers. OS10’s integrated network automation and RESTful APIs streamlined BGP-EVPN route exchange and clock-synchronized failover. The deployment achieved sub-5ms end-to-end latency, 1.2Tbps aggregate throughput, and eliminated manual configuration errors, accelerating time-to-market for new trading applications by 50%.
