S3048-ON Use Case
Data Center Leaf Switch in Hybrid Cloud Environments
In a hybrid cloud deployment, the Dell Networking S3048-ON (48x1GbE, 4x SFP+ 10GbE) functions as a leaf switch, stacked across multiple racks with DNOS 9 automation and IO-to-PSU airflow for optimal cooling. Outcome: Delivers scalable 1Gb/10Gb connectivity, reduces east-west latency by up to 20%, and automates policy enforcement to accelerate VM mobility and simplify operations.
Enterprise Campus Access Aggregation
In a multi-floor corporate campus, the S3048-ON provides 48 high-density 1GbE access ports per floor, 4x 10GbE uplinks to the distribution layer, and stackable management under DNOS 9. The IO-to-PSU airflow design lowers energy consumption in shared closets. Outcome: Centralizes port provisioning, boosts network uptime to 99.99%, and cuts maintenance overhead by 30% through unified firmware and policy updates.
High-Performance Compute Cluster Leaf Switch
In an HPC cluster, the S3048-ON delivers 4x SFP+ 10GbE uplinks for low-latency interconnects between compute nodes, with stacking for N+1 redundancy and DNOS 9-driven QoS and traffic shaping. IO-to-PSU airflow ensures reliable cooling in dense rack layouts. Outcome: Maintains sub-10 µs network jitter, increases parallel-job throughput by 15%, and ensures predictable performance for compute-intensive workloads.
