N2K-C2348UPQ Use Case
High-Density Virtualized Data Center Uplinks
Deploy N2K-C2348UPQ as a top-of-rack fabric extender in a private cloud with 48 x 1/10GE SFP+ connections to hypervisor hosts and 6 x 40G QSFP uplinks to Nexus spine switches. This architecture delivers ultra-dense host connectivity, seamless scale-out and single-pane management via a parent Nexus 9000, reducing operational complexity by 30% and enabling cost-effective expansion of virtual workloads with sub-microsecond latency.
High-Performance Computing and Big Data Clusters
Integrate the N2K-C2348UPQ into an HPC or big-data analytics cluster to aggregate 48 compute nodes over 10GE SFP+ links with 6 x 40G QSFP uplinks for spine connectivity. The port density and low-latency switching accelerate distributed compute jobs, delivering up to 60% faster data shuffles and sustaining RDMA-over-Converged-Ethernet performance. Centralized management through Nexus 9000 simplifies firmware updates and QoS policies for predictable, high-throughput workloads.
Multi-Tenant Colocation and Campus Aggregation
Use N2K-C2348UPQ in a multi-tenant colocation facility or campus wiring closet to terminate 1/10GE customer links and aggregate traffic over 40G uplinks to core Nexus switches. This FEX enables rapid tenant provisioning, strict VRF-based segmentation and uniform policy enforcement. By offloading port density and spanning-tree complexity to the parent switch, operators achieve 50% faster on-boarding and maintain carrier-grade SLAs with end-to-end visibility and automated fault isolation.
