Produktbeskrivning

The Cisco Nexus 9400 Series centralized modular switches expand the Cisco Nexus 9000 Series portfolio with a chassis that supports very high port density 400 Gigabit expansion modules.

As datacenters continue to evolve to support next-generation applications such as machine learning that drive massive growth intra-datacenter traffic bandwidth, datacenter operators require compact, high capacity, and highly efficient switches to upgrade datacenter fabrics. They need security, automation, visibility, analytics, and assurance. Equipped to support this next-generation cloud architecture, the Cisco Nexus 9400 series switches are based on Cisco Cloud Scale technology.

The Cisco Nexus 9400 series centralized modular architecture can scale up to 25.6 Tbps with a combination of field replaceable switch card, expansion modules, power supplies, and fans.

The Cisco Nexus 9400 series switch has a design with height of 4 RU and depth of 24 inches including eight expansion slots.

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

 

Egenskaper

Architectural flexibility
The Cisco Software-Defined Networking (SDN) solution with Cisco ACI support. Cisco ACI is a holistic, intent-driven architecture with centralized automation and policy-based application profiles. It provides a robust transport network for dynamic workloads and is built on a network fabric that combines time-tested protocols with the innovations to create a highly flexible, scalable, and resilient architecture of low-latency, high-bandwidth links. This fabric delivers a network that can support the most demanding and flexible 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 9000 Series, 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. Three-tier BGP architectures, enabling horizontal, nonblocking IPv6 network fabrics at web scale. 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). It provides a control-plane alternative for increased network scalability and virtualization. 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).

Extensive programmability
Day-0 automation through Power On Auto Provisioning (POAP), drastically reducing provision time. The integrations for leading DevOps configuration management applications, such as Ansible, Chef, Puppet, and SALT. Extensive native YANG and industry-standard OpenConfig model support through RESTCONF/NETCONF. Pervasive APIs for all switch Command-Line Interface (CLI) functions (JSON-based RPC over HTTP/HTTPs).

High scalability, flexibility, and security
Flexible forwarding tables support up to two million shared entries. IEEE 802.1ae MAC Security (MACsec) and CloudSec (VTEP to VTEP encryption) capability on all ports, allows traffic encryption at the physical layer and provides secure server, border leaf, and leaf-to-spine connectivity.

Intelligent buffer management
The platform offers Cisco's innovative intelligent buffer management, which offers the capability to distinguish mice and elephant flows and apply different queue management schemes to them based on their network forwarding requirements in the event of link congestion.

Remote Direct Memory Access (RDMA) over converged Ethernet - RoCE support
The platform offers lossless transport for Remote Direct Memory Access (RDMA) over converged Ethernet with support of Data Center Bridging (DCB) protocols: Priority-based Flow Control (PFC) prevents drops in the network and pause-frame propagation per priority class. Enhanced Transmission Selection (ETS) reserves bandwidth per priority class in network contention situations. Data Center Bridging Exchange Protocol (DCBX) can discover and exchange priority and bandwidth information with endpoints. The platform also supports Explicit Congestion Notification (ECN), which provides end-to-end notification per IP flow by marking packets that experienced congestion, without dropping traffic. The platform is capable of tracking ECN statistics, including the number of marked packets that have experienced congestion.

Hardware and software high availability
Virtual Port-Channel (vPC) technology provides Layer 2 multipathing through the elimination of Spanning Tree Protocol (STP). It also enables fully utilized bisectional bandwidth and simplified Layer 2 logical topologies without the need to change the existing management and deployment models. The 64-way 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. Advanced reboot capabilities include hot and cold patching. The switches use hot-swappable Power-Supply Units (PSUs) and fans with N+1 redundancy.
