Cisco Nexus 9408 High Density & Modular

The Cisco Nexus 9408 Series N9K-C9408 centralized modular switches expand the Cisco Nexus 9000 Series portfolio with a new chassis that supports very high port density 400 Gigabit expansion modules.

Cisco Nexus 9408 Modular Architecture

The centralized modular architecture boasts the impressive capacity to scale up to 25.6 Tbps. This remarkable scalability is achieved through the adept utilization of a combination of field-replaceable switch cards, expansion modules, power supplies, and fans. Furthermore, this flexible architecture ensures seamless expansion and adaptation to evolving network requirements, thereby providing organizations with unparalleled agility and resilience in meeting their ever-changing needs.

Newer Design

The Cisco Nexus 9408 series N9K-C9408 switch introduces a new design, featuring a height of 4 RU and a depth of 24 inches.  Additionally, it includes eight expansion slots aimed at supporting either 64 ports of 400 Gigabit or 128 ports of 200 G.

Furthermore, the chassis architecture supports a supervisor, and up to 8 expansion modules, fan tray redundancy with 5 fan trays, and power supply redundancy.

Two Applications

Cisco offers two modes of operation for Cisco Nexus 9408 Switches. In this regard, organizations have the option to deploy either Cisco Application Centric Infrastructure (Cisco ACI) or Cisco NX-OS mode, providing them with the flexibility to choose the mode that best aligns with their specific requirements and infrastructure preferences.

Cisco Nexus 9408 Architectural flexibility

● Showcasing an industry-leading Cisco Software-Defined Networking (SDN) solution bolstered by Cisco ACI, a holistic architecture propelled by intent. In essence, Cisco ACI ensures centralized automation and operates on policy-based application profiles. Additionally, it establishes a robust transport network ideally suited for dynamic workloads. Constructed on a network fabric that seamlessly integrates time-tested protocols with cutting-edge innovations.  It effectively forges a highly flexible, scalable, and resilient architecture. This architecture is further characterized by its low-latency, high-bandwidth links, ensuring optimal performance and efficiency. Ultimately, this fabric empowers a network that is exceptionally adept at supporting even the most demanding and adaptable data center environments.  
●  Purpose-built Cisco NX-OS Software operating system with comprehensive, proven innovations. A single binary image supports every switch in the Cisco Nexus 9408 Series N9K-C9408, simplifying image management. The operating system is modular, with a dedicated process for each routing protocol: a design that isolates faults while increasing availability.
●  Support for standards-based VXLAN EVPN fabrics, inclusive of hierarchical multisite support. (Refer to VXLAN network with MP-BGP EVPN control plane for more information.)
● Furthermore, it offers three-tier BGP architectures, enabling horizontal, nonblocking IPv6 network fabrics at web scale.
● In addition, Segment Routing (SR and SRv6) allows the network to forward Multiprotocol Label Switching (MPLS) packets and engineer traffic without Resource Reservation Protocol (RSVP) Traffic Engineering (TE). This provides a control-plane alternative for increased network scalability and virtualization.
● Moreover, it provides comprehensive protocol support for Layer 3 (v4 and v6) unicast and multicast routing protocol suites, including BGP, Open Shortest Path First (OSPF), Enhanced Interior Gateway Routing Protocol (EIGRP), Routing Information Protocol Version 2 (RIPv2), Protocol Independent Multicast Sparse Mode (PIM-SM), Source-Specific Multicast (SSM), and Multicast Source Discovery Protocol (MSDP).
● 400 Gigabit switch expansion modules.
