Cisco Nexus 9300 64-Port 400G Switch | Data Center Switch — CON-SSSW-N9K9364C

Push more traffic through fewer switch hops with a platform engineered for dense 400G connectivity. The Nexus 9300 Series 64-port 400G switch is designed for modern data center fabrics where port count, bandwidth, and operational consistency directly affect application performance and expansion planning. With 64 x 400G ports, this model is built for environments that need to aggregate massive east-west traffic without filling racks with lower-density hardware. That makes it a strong fit for leaf-spine architectures, high-capacity border roles, and large-scale interconnects where every rack unit must justify itself. The result is a cleaner fabric design, fewer cable runs, and more headroom for future workload growth. The SSPT no RMA designation points to a support posture intended for organizations that already have strict replacement and service processes in place. For procurement teams, this can be a deliberate choice when the priority is matching support terms to internal operations rather than paying for bundled replacement coverage that may not be needed. In practice, this model serves teams that value dense 400G switching and want to invest in fabric capacity where it has the most impact. Ideal For Leaf-spine data center fabric deployments High-capacity aggregation for AI and compute clusters Border or spine roles in large enterprise data centers Dense interconnects where 400G port count is critical Why This Product 1 64 x 400G ports for extreme fabric density 2 Nexus 9300 platform for data center switching 3 Better fit for leaf-spine designs than lower-speed models 4 SSPT no RMA support aligns with controlled service workflows
