The Cisco Nexus 9000 Series Switch portfolio is a versatile and streamlined portfolio of distributed modular, centralized modular, and fixed switches that cover all data center requirements – super spine, spine, leaf, and border leaf.
Built on Cisco silicon, the Cisco Nexus 9000 Series delivers industry-leading data center performance from the inside out.
800G ports for heavy lifting
For data requirements big or small, multispeed ports have your back with full backward compatibility. They can flex and scale with you, while you handle the growth.
Seeing is securing
Toughen, tighten, and protect your network with streaming telemetry, advanced analytics, and line-rate encryption (MACsec).
The bottom line counts
Reduce operational costs with unified ports supporting 10/25G Ethernet and 8/16/32G Fibre Channel, RDMA over converged Ethernet (RoCE), and IP storage.
The speed you need
Dial in performance with intelligent buffers and zero packet drop for 50 percent faster application completion time.
