Cisco Nexus 9300 48x 10/25G SFP+ 6x 100G QSFP28 | Data Center Switch — CON-L14OS-ISR4331S

Move traffic with the port density and uplink headroom modern data centers demand. Cisco Nexus 9300 switching gives infrastructure teams a fabric-ready platform with 48 10/25G SFP ports and 6 100G QSFP28 uplinks, making it well suited for leaf-spine designs, server aggregation, and high-throughput east-west traffic. This class of switch is built for environments where oversubscription, latency, and operational consistency matter. The mix of 10/25G access ports and 100G uplinks helps preserve bandwidth as workloads scale, while the Nexus family is known for disciplined control in enterprise and cloud data center networks. That makes it a strong fit for teams standardizing on Cisco switching across core racks, aggregation layers, and high-density compute clusters. For buyers comparing against lower-capacity alternatives, the value is in the margin it preserves. More uplink capacity, more access density, and a platform designed for data center switching reduce the need for early refreshes and awkward port compromises. If your network roadmap includes virtualization, storage traffic, or rapid server growth, this model gives you room to expand without redesigning the fabric. Ideal For Leaf-spine data center fabric deployment Server aggregation in virtualization clusters High-bandwidth uplinks for storage and east-west traffic Rack-level switching for enterprise compute environments Why This Product 1 More uplink headroom than access-focused switches 2 Better fit for leaf-spine fabrics than campus models 3 Higher port density for server aggregation 4 Cisco Nexus platform alignment for data center standardization
