Cisco Nexus 9000 Series
Performance and scale
for the AI era
From compact 400G fixed switches to modular 800G platforms, the Nexus 9000 Series gives your data center the bandwidth, intelligence, and programmability to support AI/ML workloads and cloud-scale fabrics.
Built for data centers that never slow down.
The Nexus 9000 Series delivers industry-leading performance on Cisco Silicon One — with lossless AI/ML fabrics, programmable pipelines, and zero-compromise security.
400G and 800G performance
Handle massive AI/ML and cloud traffic with line-rate 400G and 800G switching across fixed and modular platforms.
Lossless AI/ML fabrics
Advanced flow control and adaptive routing ensure zero packet drop for RoCE and RDMA traffic in GPU training clusters.
Programmable at every layer
P4-programmable ASICs, model-driven telemetry, and Nexus Dashboard give your team complete visibility and automation.
Secure by design
Line-rate MACsec encryption and VXLAN BGP EVPN segmentation protect your data center from the inside out.
