Cisco ONE Nexus 9300 48x 10/25G SFP + 6x 100G QSFP28 | Data Center Switch — CON-SSSW-C1N9KYEX

Move demanding data center traffic with a switch built for dense access and high-speed uplinks. The Cisco ONE Nexus 9300 pairs 48 10/25G SFP ports with 6 100G QSFP28 ports, giving infrastructure teams a clean way to aggregate server racks, storage nodes, and leaf-spine connections in a single platform. This configuration is well suited to environments where port mix matters as much as raw bandwidth. The 10/25G SFP side supports modern server connectivity, while the 100G QSFP28 uplinks provide the headroom needed for spine connections, cluster expansion, and traffic bursts during backup or replication windows. That balance helps avoid the cost of overspecifying every edge port while still preserving a fast fabric core. For teams standardizing on Cisco Nexus switching, this model fits into operational patterns built around data center segmentation, predictable forwarding, and high port density. It is a strong choice when you need to simplify rack design, reduce cable sprawl, and keep the network ready for workload growth without redesigning the fabric. Ideal For Leaf switch for a modern data center fabric Top-of-rack aggregation for compute-heavy server racks High-speed uplink layer for storage and virtualization clusters Network core segment in Cisco-based enterprise data centers Why This Product 1 More uplink headroom than 10G-only access switches 2 Higher port density than smaller aggregation models 3 Better fabric fit than access switches without 100G uplinks 4 Designed for data center traffic patterns, not office LAN use
