Data Sheet Cisco Nexus 9300 Switches Product Overview Organizations everywhere recognize that changing application environments are creating new demands for the IT infrastructure that supports them. Application workloads are deployed across a mix of virtualized and nonvirtualized server and storage infrastructure, requiring a network infrastructure that provides consistent connectivity, security, and visibility across a range of bare-metal, virtualized, and cloud computing environments: ● Application instances are created dynamically. As a result, the provisioning, modification, and removal of application network connectivity needs to be dynamic as well. Business units demand accelerated application deployments. IT departments have to provide shared IT infrastructure to address time-to-market needs and to increase their return on investment (ROI). With organizations deploying a mix of custom, open source, and off-the-shelf commercial applications, IT departments must manage both security and quality of service (QoS) for environments that support multitenancy. Applications have been transitioning over time to a less monolithic, scale-out, multinode model. IT infrastructure that supports this model must scale with the speed of business and support both 10 and 40 Gigabit Ethernet connectivity. The Cisco Nexus® 9000 Series Switches include both modular and fixed-port switches that are designed to overcome these challenges with a flexible, agile, low-cost, application centric infrastructure (ACI). The Cisco Nexus 9300 platform is composed of fixed-port switches designed for top-of-rack (ToR) and middle-ofrow (MoR) deployment in data centers that support enterprise applications, service provider hosting, and cloud computing environments. Cisco Nexus 9300 Series Switches are Layer 2 and 3 nonblocking 10 and 40 Gigabit Ethernet and Fibre Channel over Ethernet (FCoE)-capable switches with up to 1.28 terabits per second (Tbps) of internal bandwidth. The Cisco Nexus 9396PX Switch is a two-rack-unit (RU) switch that supports 960 Gbps of bandwidth across 48 fixed 10-Gbps SFP+ ports and 12 fixed 40-Gbps QSFP+ ports (Figure 1). The 40-Gbps ports are provided on an uplink module that can be serviced and replaced by the user. Figure 1. Cisco Nexus 9396PX Switch The Cisco Nexus 93128TX Switch is a 3RU switch that supports 1.28 Tbps across 96 fixed 1/10GBASE-T ports and 8 fixed 40-Gbps QSFP ports (Figure 2). The 40-Gbps ports are provided on an uplink module that can be serviced and replaced by the user. The uplink module is the same for both switches. If used with the Cisco Nexus 93128TX 8 out of the 12 40Gbps QSFP+ ports are available. © 2014 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public Information.

Cisco Nexus 93128TX Switch With the Cisco Nexus 9000 Series, organizations can quickly and easily upgrade existing data centers through advanced optics that enable the use of existing 10 Gigabit Ethernet fiber (a pair of multimode fiber strands) to carry 40 Gigabit Ethernet to the aggregation layer or to the spine (in a leaf-and-spine configuration). Additionally, the series can be deployed in MoR or end-of-row (EoR) configurations to meet the 10 Gigabit Ethernet connectivity requirements of multiple racks or pods. Used with Cisco Nexus 2000 Series Fabric Extenders, the switches can support...

The Cisco Nexus 9300 platform delivers the capabilities described in Table 2. Table 2. Cisco Nexus 9300 Platform Capabilities Predictable high performance Latency of 1 to 2 microseconds with up to 1.28 Tbps of bandwidth enables customers to build a robust switch fabric scaling from as few as 200 10-Gbps server ports to more than 200,000 10-Gbps server ports. Increased integrated buffer space Total of 50 MB of integrated shared buffer space to better manage speed mismatch between access and uplink ports. Hot-swappable, redundant power supplies and fan trays increase availability. Flexible...

Cisco Nexus M12PQ 12-Port QSFP+ Uplink Card 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/EoR access-layer switches deployed with or without Cisco fabric extender technology, and as leaf switches in horizontally scaled leaf-and-spine architectures. In the context of Cisco ACI, the Cisco Nexus 9300 platform is designed for a leaf role. Top-of-Rack Data Center Switch The Cisco Nexus 9300 platform is designed with the port density, increased integrated buffer space, and...

End-of-Row Access-Layer Switch In addition to being an excellent ToR switch, Cisco Nexus 9300 platform switches can be configured as MoR/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 6): ● 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 The Cisco Nexus 9396PX can be used to connect both 10 and 40 Gigabit Ethernet-equipped fabric extenders, Cisco Nexus B22...

Using Cisco Nexus 2000 Series Fabric Extenders at the top of each rack reduces 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. Figure 7. Collapsed Access and Aggregation Layers with Cisco Fabric Extenders Leaf-and-Spine Architecture Cisco Nexus 9300 platform switches are excellent choices for leaf switches...

Cisco NX-OS Software Overview Cisco NX-OS is a data center purpose-built operating system designed for performance, resiliency, scalability, manageability, and programmability at its foundation. Cisco NX-OS 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 Cisco NX-OS Software with a single binary image that supports every switch in the series, simplifying image management. The operating system is modular, with a dedicated process...
