The Cisco Nexus 9000 series switches include both modular (Nexus 9500 switches) and fixed-port switches (Nexus 9300 switches). The Cisco Nexus 9000 switches are the next generation of data center switching infrastructure by providing two modes of operation: Cisco NX-OS mode and ACI mode.
In Cisco NX-OS Software mode, the Cisco Nexus 9000 Series addresses the new challenges of current infrastructure designs, while building on first-generation software-defined networking (SDN) solutions and providing a path to Cisco Application Centric Infrastructure (ACI). In Cisco ACI mode, the Cisco Nexus 9000 Series provides the industry’s most advanced answer to SDN with a powerful combination of hardware and software custom developed to provide a more robust and comprehensive solution than anything else available on the market.
