Expanding the Nexus 7000 family

November 4, 2011 - 1 Comment

Cisco recently announced the Nexus 7009 chassis expanding the Nexus 7000 family to 3 chassis. To refresh your memory on the Nexus 7000 family, here’s a quick at a glance comparison.

I often get asked, why Cisco introduced a 9 slot chassis when we already have a 10 slot chassis. The simple answer is – customers asked for a smaller form factor Nexus 7000 switch that delivers the high performance and resiliency that the Nexus 7000 family is known for.

At 14 RU, the Nexus 7009 is 7 RU smaller than the Nexus 7010 making it ideal for space constrained deployments. Even though it’s a significantly smaller footprint, the Nexus 7009 maintains feature and configuration consistency across the family by using the same supervisor, I/O modules and power supplies as the Nexus 7010 and the Nexus 7018. From a common sparing and deployment perspective, this is great news!

Another key difference between the Nexus 7009 and Nexus 7010 is the air flow. The Nexus 7009 is designed for side-to-side airflow whereas the Nexus 7010 is optimized for front-to-back airflow.

So, how do you decide which one is right for your deployment?

For data centers that are designed for hot/cold-aisle, the Nexus 7010 is the ideal choice with front-to-back flow. It simplifies deployments without additional complexity or re-directing air flow. Also, the Nexus 7010 has one more I/O slot. It doesn’t sound like much…but that’s an additional 48 10GE ports. One day you’ll be thankful for that extra slot!

The Nexus 7009’s small form factor opens up new deployment design opportunities in both the data center and the campus core. In the data center, where front to back airflow is not a requirement and space is limited, you can rack and stack 3 Nexus 7009’s in a single 42RU rack delivering just over 1,000 10GE port density per rack.

For campus core deployments where high performance and 10GE density is a key requirement, the Nexus 7009 delivers up to 8Tbps of performance and 336 line rate 10GE port density. However, if services are the key requirement, the Catalyst 6500 with the Sup2T is still the industry leader delivering the highest level of services and features.

In summary, the Nexus 7009 is optimized for space and the Nexus 7010 is optimized for front to back air flow. With the addition of the Nexus 7009, we’ve broadened the deployment options for the Nexus 7000 family in both the data center and campus core. For more information on the Nexus 7009, please visit

  1. Well done! I think integrating NX-OS into the campus core is a great idea. Working with the Nexus, I think that there are some revolutionary pieces that all switches can benefit from including the embedded wireshark, standby partitioning, and enabling services on an as needed basis.

    I will continue to be a fan of seeing both shops at Cisco come together to bring the next generation of switching to today’s industries.
