Product 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.

Figure 1.           

Cisco Nexus 9000 Series Switch Chassis

The Cisco Nexus 9500 Series modular switches are capable of supporting a bandwidth of up to 172.8 Terabits per second (Tbps) with a comprehensive selection of line cards that provide 1-, 10-, 25-, 40-, 50-, and 100-Gigabit Ethernet interfaces. Using these line cards, the Cisco Nexus 9500 Series switches can be configured with up to

1.     576 100-Gigabit Ethernet ports (or)

2.     576 40-Gigabit Ethernet ports (or)

3.     2304 25-Gigabit Ethernet ports (or)

4.     2304 10-Gigabit Ethernet ports

The supervisor, system controller, power supplies, and line cards are common across all three switches. Each switch, however, has unique fabric modules and fan trays that plug in vertically in the rear of the chassis.

Table 1.          Features and Benefits

Feature

Benefit

High performance

The Cisco Nexus 9500 Series cloud-scale switch delivers up to 172.8 Tbps of nonblocking performance at a latency of 5 microseconds or less at 100-, 50-, 40-, 25-, 10-, and 1-Gigabit Ethernet speeds. This enables customers to build robust and scalable high-speed fabrics that can support several thousands of high-speed access ports.

Telemetry

The Cisco Nexus 9500 Series cloud-scale switches support extensive switch and flow telemetry capabilities that provide extensive real-time visibility into switch and fabric states.

High-density 1-, 10-, 25-, 40- and 50-Gigabit Ethernet access configuration

Organizations can transition from low-speed (100-Megabit Ethernet and 1-Gigabit Ethernet) server access designs to high-speed (1-, 10-, 25-, 40-, and 50-Gigabit Ethernet) server access designs with the same port density.

High-density 10-, 40-, and 100-Gigabit Ethernet aggregation and spine configuration

The Cisco Nexus 9500 Series Switches help organizations transition from 1- and 10-Gigabit Ethernet infrastructure to 10-, 40-, and 100-Gigabit Ethernet infrastructures to support the increased bandwidth demands of scale-out, multinode application environments. The compatibility of 100-Gigabit Ethernet QSFP28 modules with 40-Gigabit Ethernet QSFP+ modules enables the migration and coexistence of 40- and 100-Gigabit Ethernet ports in the fabric.

High availability, reliability, and scalability

The Cisco Nexus 9500 Series Switches are designed with redundant supervisors, system controllers, power supplies, and fan trays, which eliminate any single point of failure in the chassis. These switches also support up to 6 fabric modules, which provide redundancy and graceful degradation of switching capacity in the event of fabric module failures. All transceivers are pluggable to support the highest possible Mean Time Between Failure (MTBF) for the switch.

Designed for the future

The Cisco Nexus 9500 Series Switches are designed for future expansion with the capability to support higher speed ports and more bandwidth.

Power efficiency

The Cisco Nexus 9500 Series Switches are the first switch chassis designed without a midplane. The line cards and fabric modules connect directly. This revolutionary design provides optimal front-to-back airflow and helps the switch operate with less power. In addition, all Cisco Nexus 9500 Series switch power supplies are rated at or higher than 80PLUS Platinum for AC inputs and equivalent efficiency for DC inputs.

The typical power consumption per 10-Gigabit Ethernet port is less than 3.5 watts (W).

The typical power consumption per 40- and 100-Gigabit Ethernet port is less than 14W and 22W respectively.

Deployment Scenarios

The Cisco Nexus 9500 Series Switches support various deployment scenarios:

     Spine nodes in a spine-leaf fabric

     Core or aggregation node in an L2/L3 network

     Border gateway in a L2/L3 network

Spine-Leaf Fabric Architecture

The high port-density and ability to support multispeed ports on the same chassis make the Cisco Nexus 9500 Series Switches the ideal choice as a spine in spine-leaf fabric architectures. The Cisco Nexus 9500 Series Switches can function as a spine in either Cisco Application Centric Infrastructure (Cisco ACI) or Cisco NX-OS operating modes (Figure 1).

datasheet-c78-729404_1.jpg

Figure 2.           

Spine-Leaf Architecture using Cisco Nexus 9300 and 9500 Switches

Cisco ACI is the most comprehensive solution to enable data center automation and application agility. It provides a secure, scalable, deterministic, and integrated policy-based architecture, which enables rapid application deployment and workload mobility in data centers. The Cisco Nexus 9000 Series cloud-scale switches are the foundation to deploy and run Cisco ACI. The Cisco Nexus 9500 Series cloud-scale switches and select Cisco 9300 Series cloud-scale switches provide the ACI spine functionality in the Cisco ACI fabric. The Cisco Nexus 9300 Series cloud-scale switches provide the ACI leaf functionality in the Cisco ACI fabric.

In Cisco NX-OS mode, the Cisco Nexus 9500 Series Switches support foundational routing and switching technologies along with modern technologies such as VXLAN with BGP-EVPN control plane, segment routing, MPLS, and open APIs. These technologies provide the flexibility to build spine-leaf data center fabrics or classical three-tier data center networks. In this mode, the Cisco® Data Center Network Manager (DCNM) can manage the Cisco Nexus 9500 Series Switches.

Core, Aggregation, and Gateway Roles

The Cisco Nexus 9500 Series Switches support line cards that provide a choice of smart buffers, deep buffers, large tables, and high-density, high-speed Ethernet interfaces. These hardware capabilities, along with extensive routing and switching software capabilities, make the Cisco Nexus 9500 Series Switches an excellent choice as a core, aggregation, or gateway switch.

End-of-Row Access Layer Switch

As the Cisco Nexus 9500 Series Switches support high-density, multispeed Ethernet ports, these switches can also be deployed as end-of-row switches providing access connections to blade or rack servers. The Cisco Nexus 9500 Series Switches also provide the flexibility to incrementally transition from lower-speed server connections to higher-speed server connections.

Supervisor Modules for the Cisco Nexus 9500 Series

A pair of redundant supervisor modules manages all switch operations using a state-synchronized, active-standby model. The supervisor accepts an external clock and supports management through multiple ports – two USB ports, a serial port, and a 10/100/1000-Mbps Ethernet port. All supervisors support Cisco ACI or NX-OS deployments. Redundant supervisors should be of the same type within a chassis.

Cisco Nexus 9500 Platform Power Supply

The Cisco Nexus 9500 platform supports hot-swappable, front-panel-accessible AC, DC, and universal high voltage AC/DC power supplies. N+1 and N+N redundancy modes are supported depending on the chassis configuration.

The 3150W high voltage AC/DC power supply offers two power inputs each of which can provide up to 3150 W of output power. This unique capability allows provisioning grid redundancy without doubling the required number of power supplies.
