Overview:
Application architectures and deployment modes are rapidly evolving. Modern applications are multinode, highly modular, and deployed over a combination of bare-metal, virtual, and cloud data center environments. In addition to that, individual departments within an organization have varying infrastructure and networking needs. These factors require that data center networks be simple, programmable, extensible, scalable, and shareable to meet the demands of applications.
The Cisco Nexus 9000 Series Switches operate in one of two modes - Cisco Application Centric Infrastructure (Cisco ACI™) or Cisco NX-OS. In Cisco ACI mode, these switches provide a turnkey, fully automated, policy-based architecture to design and manage data center fabrics. In Cisco NX-OS mode, these switches provide the capability to use foundational layer 2/3 technologies, as well as modern technologies such as VXLAN, with a Border Gateway Protocol‒Ethernet VPN (BGP-EVPN) control plane, Segment routing, Multiprotocol Label Switching (MPLS), and automation via NX-APIs.
The Cisco Nexus 9000 Series Switches include the Nexus 9500 Series modular switches and the Nexus 9200/9300 Series fixed switches.
The Cisco Nexus 9500 Series modular switches support a comprehensive selection of line cards and fabric modules that provide 1-, 10-, 25-, 40-, 50-, 100-, 200-, and 400-Gigabit Ethernet interfaces. Using these line cards the Cisco Nexus 9500 Series switches can be configured with up to.
- 256 400-Gigabit Ethernet ports (or)
- 524 200-Gigabit Ethernet ports# (or)
- 1024 100-Gigabit Ethernet ports (or)
- 2048 50-Gigabit Ethernet ports (or)
- 1024 40-Gigabit Ethernet ports (or)
- 2304 25-Gigabit Ethernet ports (or)
