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 9508 Switch (Figure 1) is an ACI modular spine device enabled by a nonblocking 40 Gigabit Ethernet line card, supervisors, system controllers, and power supplies.

Figure 1.      Cisco Nexus 9508 ACI Switch

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

Cisco Nexus 9500 Platform Features and Benefits

The Cisco Nexus 9508 is a modular chassis that supports up to eight line cards, two supervisor modules, two chassis controllers, three fan trays, six fabric modules, and eight power supplies. The switch supports comprehensive Layer 2 and 3 functions on nonblocking 1, 10, and 40 Gigabit Ethernet ports. Table 1 summarizes the features and benefits of the Cisco Nexus 9500 platform.

Capability

Benefit

Predictable high performance

The switch delivers up to 30 terabits per second (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 10 Gigabit Ethernet server ports to more than 200,000 10 Gigabit Ethernet server ports.

Nonblocking, high-density 1 and 10 Gigabit Ethernet configuration

The Cisco Nexus 9500 platform helps organizations transition from existing 1 Gigabit Ethernet Cisco Catalyst® 6500 Series Switches server access designs to 10 Gigabit Ethernet server access designs with the same port density.

Nonblocking, high-density 10 and 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 Enhanced Quad Small Form-Factor Pluggable (QSFP+) bidirectional transceiver that enables customers to use existing 10 Gigabit Ethernet data center cabling to support 40 Gigabit Ethernet connectivity. This technology facilitates adoption of 40 Gigabit Ethernet with no 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 line cards use a mix of merchant and Cisco® application-specific integrated circuits (ASICs) to produce a low-complexity, low-cost design. 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.

Chassis designed for 2 to 3 future generations of line cards

The flexible and efficient chassis design has 100% 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 Fabric Modules

The Cisco Nexus 9500 platform internally 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. 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 (Table 3).

Cisco Nexus 9500 Platform Supervisor Module

A pair of redundant supervisor modules manages all switch operations using a state-synchronized active-standby model. Each supervisor module includes a quad-core CPU, 16 GB of RAM, and a 64-GB solid-state drive (SSD) for bootup and analytics information. The supervisor accepts an external clock and supports management through various ports including two USB ports, a serial console, and a 10/100/1000-Mbps network port.

Cisco Nexus 9500 Platform System Controller

A pair of redundant system controllers offloads chassis management functions from the supervisor modules. It is responsible for managing power supplies and fan trays and is a central point for the Gigabit Ethernet out-of-band channel (EOBC) 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 four power supply slots are not needed with existing line cards but offer headroom to support higher-bandwidth line cards in the future.

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 to access them.

Deployment Scenarios

Cisco ACI Leaf-and-Spine Architecture

Cisco Application Centric Infrastructure (ACI) 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 the industry move to 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 merchant and ASIC technology forms the leaf 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.
