Cisco Nexus 9300 48x 10G SFP + 12x 100G QSFP28 | Data Center Switch — CON-ETSOP-N9KC9FX3

Move more traffic through fewer hops with a Nexus 9300 switch built for dense data center fabrics. The 48 x 10G SFP port layout supports high-port-count server access, while 12 x 100G QSFP28 uplinks provide the bandwidth needed for spine connections, aggregation tiers, and storage-heavy environments. This class of switch is designed for teams that need predictable throughput, strong oversubscription control, and a clean path to higher-speed uplinks as demand rises. It fits naturally into leaf-spine architectures, virtualization clusters, and environments where east-west traffic dominates. The port mix helps reduce the need for multiple smaller switches, simplifying cabling and rack planning while preserving headroom for growth. For infrastructure teams standardizing on Cisco switching, the Nexus 9300 family is a familiar choice for operational consistency and fabric-scale deployment. It is well suited to environments where port density, 100G uplink capacity, and data center alignment matter more than entry-level pricing. This is the kind of switch you buy when the network is expected to carry serious load, not just connect endpoints. Ideal For Leaf-spine data center fabric aggregation Virtualization cluster access switching High-density server rack connectivity Storage and east-west traffic aggregation Why This Product 1 Higher uplink density than access switches with 12 x 100G QSFP28 ports 2 More server-facing capacity than compact aggregation models with 48 x 10G SFP ports 3 Better suited to data center fabrics than campus access switches 4 Designed for traffic-heavy east-west workloads rather than basic endpoint connectivity
