Changing application environments are placing new demands on your IT infrastructure. With application workloads deployed across a mix of virtualized and nonvirtualized server and storage infrastructure, your network must provide constant connectivity, security, and visibility across bare-metal, virtualized, and cloud computing environments. For example:

●   Application instances are created dynamically, so provisioning, modification, and removal of application network connectivity also need to be dynamic.

●   With business units demanding accelerated application deployments, your IT department needs to provide a shared IT infrastructure that addresses time-to-market needs and an increased Return On Investment (ROI).

●   When you deploy a mix of custom, open-source, and off-the-shelf commercial applications, your IT department must manage security and Quality of Service (QoS) for environments that support multitenancy.

●   With applications transitioning to a less monolithic, scale-out, multinode model, your IT infrastructure must scale with the speed of business and provide support for 100 Megabit Ethernet connectivity and 1, 10, 25, 40, 50, and 100 Gigabit Ethernet connectivity.

The Cisco Nexus® 9000 Series Switches include modular and fixed-port switches that overcome these challenges with Cloudscale Technology enabled infrastructure that is flexible, agile, and programmable.

The Cisco Nexus 9500 platform, part of the Cisco Nexus 9000 Series (Figure 1), offers three modular options: the Cisco Nexus 9504 Switch with 4 slots, the Cisco Nexus 9508 Switch with 8 slots, and the Cisco Nexus 9516 Switch with 16 slots. All three switches use the same supervisor, system controller, power supplies, and line cards[1]. The Cisco Nexus 9500 platform consists of Layer 2 and 3 nonblocking Ethernet switches with backplane bandwidth of up to 115.2 Terabits per second (Tbps). The Cisco Nexus 9504, 9508, and 9516 Switches support 1, 10, 25, 40, 50, and 100 Gigabit Ethernet interfaces through a comprehensive selection of modular line cards. Configurable with up to 2304 x 10 Gigabit Ethernet ports, 2048 x 25 Gigabit Ethernet ports, 576 x 40 Gigabit Ethernet ports, 1024 x 50 Gigabit Ethernet ports, or 512 x 100 Gigabit Ethernet ports, they provide ample capacity for both access- and aggregation-layer deployments.

Features and Benefits


  • Predictable high performance
  • High-density 1, 10, 25, 40 and 50 Gigabit Ethernet access configuration
  • High-density 10, 40 and 100 Gigabit Ethernet aggregation and spine configuration
  • Highly available, scalable, and robust solution
  • Chassis designed for 2 to 3 future generations of line cards
  • Power efficiency


  • The backplane delivers up to 172.8 Tbps of nonblocking performance with latency of less than 5 microseconds, enabling data center customers to build a robust network fabric that can scale from as few as 200 x 10 and 25 Gigabit Ethernet server ports to more than 200,000 x 10 and 25 Gigabit Ethernet server ports.
  • The Cisco Nexus 9500 platform helps organizations transition from existing 100 Megabit Ethernet and 1 Gigabit Ethernet server access designs using Cisco Catalyst® 6500 Series Switches to 1, 10, 25, 40 and 50 Gigabit Ethernet server access designs with the same port density.
  • The Cisco Nexus 9000 Series helps organizations transition from 1 and 10 Gigabit Ethernet infrastructure to 10, 40 and 100 Gigabit Ethernet infrastructure to support the increased bandwidth demands of scale-out, multinode application environments. 100 Gigabit Ethernet QSFP28 module form factor compatibility with 40 Gigabit Ethernet QSFP+ enables migration and co-existence of multispeed aggregation to access layer connectivity.
  • All major components are redundant, including supervisors, system controllers, power supplies, and fan trays. All buffer memory is integrated into the forwarding ASICs, avoiding the need for a large number of external memory modules. All transceivers are pluggable to support the highest possible Mean Time Between Failure (MTBF) for the switch.
  • The flexible and efficient chassis design for future expansion, with the capability to support more bandwidth and cooling and twice the number of power supplies needed to support today’s maximum configuration.
  • The Cisco Nexus 9500 platform is the first switch chassis designed without a midplane. Line cards and fabric modules connect directly. This design approach provides optimal front-to-back airflow and helps the switch operate using less power. In addition, all Cisco Nexus 9000 Series power supplies are 80 Plus Platinum rated. The typical power consumption per 10 Gigabit Ethernet port is less than 3.5 watts (W). The typical power consumption of each 40 and 100 Gigabit Ethernet port is less than 14W and 22W respectively.
