All the Cisco Nexus 9300 platform switches use dual- core 2.5-GHz x86 CPUs with 64-GB solid-state disk (SSD) drives and 16 GB of memory for enhanced network performance.

With the Cisco Nexus 9000 Series, organizations can quickly and easily upgrade existing data centers to carry 40 Gigabit Ethernet to the aggregation layer or to the spine (in a leaf-and-spine configuration) through advanced and cost-effective optics that enable the use of existing 10 Gigabit Ethernet fiber (a pair of multimode fiber strands). Please see the Cisco 40GBASE QSFP modules data sheet for more details.

Cisco provides two modes of operation for the Cisco Nexus 9000 Series. Organizations can use Cisco^® NX-OS Software to deploy the Cisco Nexus 9000 Series in standard Cisco Nexus switch environments. Organizations also can use a hardware infrastructure that is ready to support Cisco Application Centric Infrastructure (Cisco ACI^™) to take full advantage of an automated, policy-based, systems management approach.

Features and Benefits

The Cisco Nexus 9300 platform switches are high-density, nonblocking, low-power-consuming switches designed for ToR, MoR, and end-of-row (EoR) deployment in enterprise data centers, service provider facilities, and large virtualized and cloud computing environments.

The platform offers industry-leading density and performance with flexible port configurations that can support existing copper and fiber cabling (Tables 2 and 3). With 1/10GBASE-T support, the platform can deliver 10 Gigabit Ethernet over existing copper cabling, enabling a low-cost upgrade from Cisco Catalyst® 6500 Series Switches when used in an MoR or EoR configuration.

Table 4 summarizes the features of the Cisco Nexus 9300 platform.

Table 4.       Cisco Nexus 9300 Platform Switch Features

Cisco Nexus 9300 Power and Cooling

The switches are designed to adapt to any data center hot-aisle and cold-aisle configuration. The switches can be installed with ports facing the rear, simplifying cabling of server racks by putting the ports closest to the servers they support. The switches can be installed with the ports facing the front, simplifying the upgrade of existing racks of switches in which network cables are wired to the front of the rack.

The two deployment modes support front-to-back cooling through a choice of power supplies and fan trays designed with opposite airflow directions, denoted by red and blue tabs (Figure 8).

The two deployment modes are available with AC power supplies. Additionally, DC power supply UCSC-PSU-930WDC (port-side intake) can be used for –48 to –60V DC (900W) deployments. For high-voltage AC or DC environments, customers can also choose the N9K-PUV-1200W, which supports either 200-277V AC or -200 to -380V DC and both airflow directions in one power supply unit.

To enhance availability, the platform supports 1+1 redundant hot-swappable 80 Plus Platinum-certified power supplies and hot-swappable N+1 redundant fan trays.

Cisco Nexus 9300 Platform Uplink Module

The Cisco Nexus 9300 platform requires an uplink module to be installed for normal switch operation. This module can be serviced and replaced by the user. Three uplink module options are available.

The Cisco Nexus M6PQ and M6PQ-E uplink module provides up to 6 QSFP+ ports for 40 Gigabit Ethernet connectivity to servers or aggregation-layer switches (Figure 9). The uplink module provides 6 active ports when installed in the Cisco Nexus 93128TX, 9396TX, and 9396PX. The Cisco Nexus M6PQ-E uplink module is a minor hardware revision of Cisco Nexus M6PQ. Enhancements in the hardware are transparent in NX-OS mode and offer feature parity.

The Cisco Nexus M12PQ uplink module provides up to 12 QSFP+ ports for 40 Gigabit Ethernet connectivity to servers or aggregation-layer switches (Figure 10). As specified earlier in Table 3, the uplink module provides 8 active ports when installed in the Cisco Nexus 93128TX, and 12 active ports when installed in the Cisco Nexus 9396PX and 9396TX. The 40 Gigabit ports on the uplink module do not support the break-out mode of four 10 Gigabit Ethernet ports, but they can be converted to a single 10 Gigabit Ethernet port with the QSFP-to-SFP adapter (QSA).

The Cisco Nexus N9K-M4PC-CFP2 uplink module provides up to 4 ports for 100 Gigabit Ethernet connectivity to aggregation-layer switches and routers (Figure 11). It supports CFP2 optics as well as Cisco CPAK 100-Gbps modules through converters. It provides 2 active ports when installed in the Cisco Nexus 93128TX, and 4 active ports when installed in the Cisco Nexus 9396PX and 9396TX.

Deployment Scenarios

The Cisco Nexus 9300 platform is a versatile data center switching platform with switches that can operate as ToR data center switches, as MoR and EoR access-layer switches deployed with or without Cisco fabric extender technology, and as leaf switches in a horizontally scaled leaf-and-spine architecture.

Top-of-Rack Data Center Switch

The Cisco Nexus 9300 platform is designed for a ToR architecture, with increased port density, deep integrated buffer space, and high performance (Figure 12).

With 48 fixed ports, the Cisco Nexus 9372PX/9372PX-E, 9372TX/9372TX-E, 9396PX, and 9396TX have enough ports to support the densest 1RU server configurations. A pair of these switches can support redundant connectivity to each server in a rack with ports to spare. In the configuration shown earlier in Figure 8, the 480‑Gbps uplink capacity from each switch is sufficient to provide full 10-Gbps bandwidth to each server with up to no oversubscription.

The Cisco Nexus 9300 platform can support multiple racks (or pods) of dense 1RU servers. For example, the 96‑port Cisco Nexus 93128TX and 93120TX can provide 10 Gigabit Ethernet connectivity to all servers across two racks, with a pair of these switches providing full redundancy. In less dense configurations with 2RU servers, the Cisco Nexus 9300 platform can support even more racks of servers in an MoR configuration.

End-of-Row Access-Layer Switch

In addition to being an excellent ToR switch, Cisco Nexus 9300 platform switches can be configured as MoR and EoR access-layer switches. They can connect to almost any blade or rack server through 1 and 10 Gigabit Ethernet connections including the following (Figure 13):

●   Third-party and standalone Cisco Unified Computing System™ (Cisco UCS®) rack servers

●   Third-party blade server chassis with chassis-resident switches or pass-through devices

●   Cisco UCS

The Cisco Nexus 9396PX, 9372PX, and 9372PX-E can be used to connect both 10 and 40 Gigabit Ethernet - equipped fabric extenders, Cisco Nexus B22 Blade Fabric Extenders in Dell and HP blade chassis (not shown), and 10 Gigabit Ethernet - equipped servers and systems such as Cisco UCS. The Cisco Nexus 9372TX, 9372TX-E, 9396TX, 93120TX, and 93128TX provide excellent connectivity for large numbers of 10 Gigabit Ethernet - equipped blade or rack servers equipped with 10GBASE-T ports.

Collapsed Access and Aggregation Layers

As Figure 14 shows, the Cisco Nexus 9300 platform supports Cisco Nexus 2000 Series Fabric Extenders to establish a centrally managed yet physically distributed collapsed access- and aggregation-layer switch. Although each fabric extender resides physically at the top of each rack or within each blade server chassis, each device is handled as a remote line card of the Cisco Nexus 9300 platform switch, yielding massive scalability through flexible bandwidth oversubscription but with only a single point of management.

By using Cisco Nexus 2000 Series Fabric Extenders at the top of each rack, organizations can reduce the cabling complexity, overall power consumption, and number of management points. This approach facilitates a “rack-and-roll” deployment model in which individual server racks can be prewired using ToR fabric extenders, with the only connections required to bring them into the data center being network uplink and power connections.

Leaf-and-Spine Architecture

Cisco Nexus 9300 platform switches are excellent choices for leaf switches in a leaf-and-spine architecture (Figure 15). The Layer 3 capabilities established by both the Cisco Nexus 9500 and 9300 platforms enable the two to be used with equal-cost multipath (ECMP) routing to accelerate the flow of traffic and reduce reconvergence time in the event of a failure. The degree of redundancy in a leaf-and-spine architecture delivers increased availability with a high level of flexibility in workload placement.

Cisco NX-OS Software Overview

NX-OS is a purpose-built data center operating system designed for performance, resiliency, scalability, manageability, and programmability at its foundation. It provides a robust and comprehensive feature set that meets the demanding requirements of virtualization and automation in present and future data centers.

The Cisco Nexus 9000 Series uses an enhanced version of NX-OS with a single binary image that supports every switch in the 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. In the event of a process failure, the process can be restarted without losing state. The operating system supports hot and cold patching and online diagnostics.

Main features include the following:

●   Power-On Auto Provisioning (POAP) automates the process of upgrading software images and installing configuration files on Cisco Nexus switches that are being deployed in the network for the first time.

●   Intelligent API (iAPI) provides operators with a way to manage the switch through remote procedure calls (RPCs; JavaScript Object Notation [JSON] or XML) over HTTP/HTTPS infrastructure.

●   Patching allows NX-OS to be upgraded and patched without any interruption in switch operations.

●   Line-rate overlay support provides Virtual Extensible LAN (VXLAN) bridging and routing at full line rate, facilitating and accelerating communication between virtual and physical servers as well as between multiple data centers in a campus environment.

●   Network traffic monitoring with Cisco Nexus Data Broker builds simple, scalable, and cost-effective network taps or Cisco Switched Port Analyzer (SPAN) aggregation for network traffic monitoring and analysis.

●   Cisco Intelligent Traffic Director allows customers to build a highly scalable and flexible solution for hardware-based Layer 4 load balancing and traffic steering.

The software packaging for the Cisco Nexus 9000 Series offers flexibility and a comprehensive feature set while being consistent with Cisco Nexus access switches. The default system software has a comprehensive Layer 2 security and management feature set. To enable additional functions including Layer 3 IP unicast and IP multicast routing and Cisco Nexus Data Broker, you must install additional licenses. The licensing guide illustrates the software packaging and licensing available to enable advanced features.  For a complete list of supported features, refer to Cisco Feature Navigator.

Software Requirements

The Cisco Nexus 9000 Series supports Cisco NX-OS Software Release 6.1 and later. NX-OS interoperates with any networking operating system, including Cisco IOS® Software that conforms to the networking standards described in this data sheet.

The Cisco Nexus 9000 Series runs NX-OS on a 64-bit Linux kernel (Release 3.4.10) with a single binary image that supports both modular (Cisco Nexus 9500 platform) and fixed-port (Cisco Nexus 9300 platform) switches. The software image is based on NX-OS Release 6.1(2). The single image incorporates both the Linux kernel and NX-OS so that the switch can be booted through a standard Linux kickstart process.
