Product Overview

Changing application environments are creating new demands on the IT infrastructure that supports them. With application workloads deployed across a mix of virtualized and nonvirtualized server and storage infrastructure, you require a network infrastructure that provides consistent connectivity, security, and visibility across a range of 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.

   Business units demand accelerated application deployments, so IT departments must provide a shared IT infrastructure that addresses time-to-market needs and provides a positive return on investment (ROI).

   When organizations deploy a mix of custom, open-source, and off-the-shelf commercial applications, IT departments must manage security and quality of service (QoS) for environments that support multitenancy.

   Applications are transitioning to a less monolithic, scale-out, multinode model. The 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 overcome these challenges with flexible, agile, low-cost Cisco® Application Centric Infrastructure (Cisco ACI).

The modular Cisco Nexus 9504, 9508, and 9516 Switches (Figure 1) are Cisco ACI spine devices enabled by nonblocking 40 Gigabit Ethernet line cards, supervisors, system controllers, and power supplies.

Figure 1.      Cisco Nexus 9508 ACI Components

Organizations can use ACI to take full advantage of an automated, policy-based, systems management approach.

Cisco Nexus 9500 Platform Features and Benefits

The Cisco Nexus 9500 platform is a modular chassis that supports up to 8 line cards, 2 supervisor modules, 2 chassis controllers, 3 fan trays, 6 fabric modules, and 10 power supplies in ACI mode. The switch supports comprehensive Layer 2 and 3 functions on nonblocking 1, 10, and 40 Gigabit Ethernet ports (Table 1).

Capability

Benefit

Nonblocking, high‑density 40 Gigabit Ethernet configuration

The Cisco Nexus 9000 Series helps organizations transition from 1 and 10 Gigabit Ethernet infrastructure to 10 and 40 Gigabit Ethernet infrastructure to support the increased bandwidth demands of scale-out, multinode application environments.

Advanced optics

Cisco offers a pluggable 40 Gigabit Ethernet Quad Enhanced Small Form-Factor Pluggable (QSFP+) bidirectional transceiver that enables customers to use their existing 10 Gigabit Ethernet data center cabling to support 40 Gigabit Ethernet connectivity. This feature allows adoption of 40 Gigabit Ethernet without cable infrastructure upgrade costs.

Highly available, scalable, and robust solution

All major components are redundant, including supervisors, system controllers, power supplies, and fan trays. The switch Cisco ACI line cards use Cisco application-specific integrated circuits (ASICs) to produce a low-complexity, low-cost design. 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.

Chassis designed for 2 to 3 future generations of line cards

The flexible and efficient chassis design has 100 percent headroom 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.

Power efficiency

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 Gigabit Ethernet port is less than 14W.

Cisco Nexus 9500 Platform Components for Cisco ACI Deployments

The Cisco Nexus 9500 platform enables scalable Cisco ACI deployments. Customers can choose from 4-, 8-, or 16-slot chassis options to build a Cisco ACI spine to fit their deployment scale (Table 2).

Cisco Nexus 9500 Platform Fabric Modules

The Cisco Nexus 9500 platform uses a Clos fabric design that interconnects the line cards with rear-mounted fabric modules. The Cisco Nexus 9500 platform supports up to six fabric modules, each of which provides up to 10.24-Tbps line-rate packet forwarding capacity (Table 4). All fabric cards are directly connected to all line cards. With load balancing across fabric cards, the architecture achieves optimal bandwidth distribution within the chassis.

Cisco Nexus 9500 Platform Supervisor Module

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, including two USB ports, a serial console, and a 10/100/1000-Mbps network port. Two supervisors are available to provide deployment options:

   Supervisor A: 4-core, 1.8-GHz x86 CPU, with 16 GB of RAM and 64-GB solid-state disk (SSD) drive

   Supervisor B: 6-core, 2.2-GHz x86 CPU, with 24 GB of RAM and 256-GB SSD drive

Either supervisor can be used in ACI deployments, but Supervisor B provides additional computing and storage for enhanced performance. Redundant supervisors need to be of the same type within a chassis.

Cisco Nexus 9500 Platform System Controller

A pair of redundant system controllers offloads chassis management functions from the supervisor modules. The controllers are responsible for managing power supplies and fan trays and are central points for the Gigabit Ethernet out-of-band channels (EOBCs) between the supervisors, fabric modules, and line cards.

Cisco Nexus 9500 Platform Power Supply

The Cisco Nexus 9500 platform supports up to 10 hot-swappable, front-panel-accessible power supplies. A fully loaded chassis can operate with two 3000W AC power supplies. N+1 and N+N redundancy modes are supported. The 3000W AC power supply is 80 Plus Platinum rated, providing more than 90 percent efficiency across typical workloads.

The additional unused power supply slots are not needed with existing line cards, but they offer headroom to support higher-bandwidth line cards in the future. Two power supplies are available to provide deployment options:

   N9K-PAC-3000W-B Cisco Nexus 9500 platform 3000W standard 200-to-240 VAC power supply with port-side intake

   N9K-PUV-3000W-B Cisco Nexus 9500 platform 3000W universal high-voltage AC/DC power supply with port-side intake

Cisco Nexus 9500 Platform Fan Trays

Three hot-swappable fan trays support front-to-back cooling. Each fan tray covers two fabric modules and can be removed for access.

Deployment Scenarios

Cisco ACI Leaf-and-Spine Architecture

Cisco Application Centric Infrastructure is a holistic architecture with centralized automation and policy-based application profiles. The Cisco ACI fabric is designed from the foundation to support emerging industry demands while maintaining a migration path for architecture already in place. The fabric is designed to support management automation, programmatic policy, and dynamic “workload-anywhere” models. The Cisco ACI fabric accomplishes this with a combination of hardware, policy-based control systems, and software closely coupled to provide advantages not possible in other models. For additional details, please visit http://www.cisco.com/go/aci.

The Cisco Nexus 9500 platform with Cisco ASIC technology forms the spine in these architectures (Figure 2). 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 leaf-and-spine architecture delivers increased availability with a high level of flexibility in workload placement.
