N3048 Use Case
Data Center Top-of-Rack Aggregation with Dell Networking N3048
In a modern data center requiring high-density server connectivity and low-latency east-west traffic, the Dell Networking N3048 L3 switch delivers 48x1 GbE access ports and dual 10 GbE SFP+ uplinks. By stacking up to four units and using front-to-back airflow, IT teams achieve simplified cable management, consistent QoS enforcement, and 2:1 oversubscription ratios. Outcome: 40% higher port density, 25% reduction in switch-to-switch latency, and streamlined capacity expansion without disrupting existing workloads.
Campus Edge Distribution for Secure Departmental Segmentation
Enterprises with multiple departments can deploy the Dell Networking N3048 at campus building edges to enforce Layer 3 routing and ACL-based segmentation across 48x1 GbE end-user ports. Dual combo uplinks to 10 GbE aggregation and stack capability ensure uninterrupted inter-VLAN routing and traffic isolation. Outcome: Enhanced network security with micro-segmentation, 50% faster inter-departmental data transfers, and centralized policy management via a single pane of glass.
Virtualization-Ready Access Layer for SMBs
Small-to-mid-sized businesses running virtualized workloads deploy the Dell Networking N3048 at the access layer to support 48x1 GbE virtual machine hosts and 10 GbE hypervisor uplinks. Integrated stacking and hot-swappable AC PSU deliver high availability, while advanced QoS and IPv4/IPv6 routing optimize voice, video, and data traffic. Outcome: 99.99% uptime SLAs, 35% improvement in VM migration throughput, and a future-proof infrastructure for cloud-ready services.
