Product overview

Artificial Intelligence and Machine Learning (AI/ML) applications are being used increasingly in today’s data centers, and the Cisco Nexus® 9000 Series Switches have the hardware and software capabilities to provide the right latency, congestion-management mechanisms, and telemetry to meet the requirements of those applications. The Cisco Nexus 9000 Series Switches address the need for high-performance, power-efficient, compact switching in the networking infrastructure and are designed to support 100G fabrics for next-generation leaf and spine designs.

Large-cloud and data-center networking teams require a flexible, reliable solution that efficiently manages, troubleshoots, and analyzes their IT infrastructure. In addition, they need security, automation, visibility, analytics, and assurance. Coupled with tools such as Nexus Dashboard, Cisco Nexus 9000 Series Switches are ideal platforms for building a high-performance AI/ML network fabric.

Based on the Cisco Silicon One E100 ASIC, the Cisco Nexus 9336C-SE1 is a new 36-port 100G switch. The platform supports cost-effective large-scale deployments, an increased number of endpoints, and is capable of wire-rate encryption. The platform is built on modern system architecture designed to provide high performance and meet the evolving needs of highly scalable data centers and growing enterprises.

Designed for the programmable network, the Cisco NX-OS operating system automates configuration and management for customers who want to take advantage of the DevOps operation model and tool sets. Cisco Nexus 9336C-SE1 supports Cisco NX-OS and will support VxLAN, L2/L3 (base features) and IPFM use-cases in the first release (10.6.1).

Cisco Nexus 9300 SE1 Switches Capabilities

Note: This datasheet describes hardware capabilities only. Please refer to Cisco Nexus 9336C-SE1 Readme document, NX-OS software release notes and appropriate feature documentation for more details on software support.

Features and benefits

Description

Architectural flexibility

  Cisco Nexus 9000 Series Switches support Cisco NX-OS VXLAN EVPN, Cisco IP Fabric for Media, Cisco Nexus Dashboard, and IP routed or Ethernet switched Layer-2 fabrics using a comprehensive set of unicast and multicast IPv6/IPv4 and Ethernet protocols.
  Purpose-built Cisco NX-OS Software operating system with comprehensive, proven innovations. 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.)
  Three-tier BGP architectures, enabling horizontal, nonblocking IPv6 network fabrics at web scale
  Comprehensive protocol support for Layer-3 (v4 and v6) unicast and multicast routing protocol suites, including BGP, Open Shortest Path First (OSPF), Interior System to Interior System (IS-IS), 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)
  Segment Routing (SR) allows the network to forward MultiProtocol Label Switching (MPLS) packets and engineer traffic without Resource Reservation Protocol (RSVP) Traffic Engineering (TE). It provides a control-plane alternative for increased network scalability and virtualization.
  Cisco IP Fabric for Media helps you migrate from an SDI router to an IP-based infrastructure. In an IP-based infrastructure, a single cable has the capacity to carry multiple bidirectional traffic flows and can support different flow sizes without requiring changes to the physical infrastructure.
  Cisco Nexus Dashboard provides customers complete observability into their network and solution(s) that can help them to identify and mitigate security threats, realize and remediate performance bottlenecks, adhere to data compliance, and have insight into capacity-planning operations.

Extensive programmability

  Day-0 automation through Power On Auto Provisioning (POAP), drastically reducing provision time
  Industry-leading integrations for leading DevOps configuration management applications, such as Ansible. Extensive Native YANG, and industry-standard OpenConfig model support through RESTCONF/NETCONF/gNMI
  REST API interacting with Data Management Engine (DME)
  Model-driven telemetry enhances network observability
  Third-party application-hosting using Cisco Application Framework (CAF)

High scalability, flexibility, and security

  IEEE 802.1ae MAC security (MACsec) capability on all ports, which allows traffic encryption at the physical layer and provides secure server, border leaf, and leaf-to-spine connectivity

AI/ML networking

  Cisco Nexus 9000 Series Switches support innovative congestion management and flow control algorithms along with the latency and telemetry needed to meet the design requirements of AI/ML fabrics. Refer to Cisco NX-OS release notes to check features supported.

Hardware and software high availability

  Virtual Port-Channel (vPC) technology provides Layer-2 multipathing through the elimination of Spanning Tree Protocol (STP).
  Can-do fabric link in the VXLAN environment, eliminating the need for peer-to-peer VPC
  The Equal-Cost Multipath (ECMP) routing enables the use of Layer-3 fat-tree designs. This feature helps organizations prevent network bottlenecks, increase resiliency, and add capacity with little network disruption.
  Software Maintenance Upgrades (SMUs) contain fixes for a specific defect and provide a quick resolution of critical issues.
  The switches use hot-swappable Power-Supply Units (PSUs) and fans with N+1 redundancy.

Cisco Nexus Dashboard

  Cisco Nexus Dashboard is a platform that transforms data-center networks through simplicity, automation, and analytics. Cisco Nexus Dashboard is a central management console for multiple data center sites and a common platform for hosting Cisco data center operation services. These services are available for all the data center fabrics and provide real-time analytics, visibility, assurance for network policies and operations, as well as policy orchestration for the data center fabrics, such as NX-OS deployments spanning LAN Fabric, SAN, and IP Fabric for Media (IPFM) networks. Cisco Nexus Dashboard 4.1 integrates multiple services like Insights, Orchestrator, and Fabric Controller into a single, seamless platform for data center operations.
