Cisco Nexus 9300 Series 32-Port 400G QSFP-DD | Data Center Switch — CON-NCDTC-N9KC9D3X

Move more traffic through the fabric without adding complexity. The Cisco Nexus 9300 Series 32-port 400G QSFP-DD platform is designed for modern data center cores and spines that must carry east-west traffic at scale while preserving predictable performance. Its dense 400G port profile gives infrastructure teams the headroom to support AI clusters, storage-heavy workloads, and high-bandwidth application tiers with fewer chassis and fewer interconnect constraints. This model fits environments where port density, throughput, and operational consistency matter more than generic feature lists. Cisco Nexus switching is widely used in leaf-spine architectures because it supports disciplined network design, strong automation workflows, and the stability expected in enterprise production networks. For teams standardizing on 400G uplinks, this switch helps reduce oversubscription pressure and simplifies fabric planning. Choose this platform when the cost of congestion, redesign, or port exhaustion is higher than the premium for a purpose-built data center switch. It is a strong fit for organizations building for growth, not just current demand. Ideal For Core spine deployment in a leaf-spine data center fabric High-bandwidth aggregation for AI and HPC clusters Uplink consolidation for storage-heavy virtualization environments Network modernization projects standardizing on 400G switching Why This Product 1 32 x 400G QSFP-DD ports for dense uplink design 2 Built for data center fabrics rather than access-layer switching 3 Better fit for east-west traffic and spine aggregation 4 Cisco Nexus platform alignment for enterprise operations
