Unleash the power of open networking Network modernization is the next step in data center transformation. Now companies of all sizes can leverage open networking for affordable capacity and consistent automation across the entire data center. It’s easier than you think. Join Cumulus Networks on October 29th to learn about expanded architectural choices and validated solutions around virtualization, Big Data, and OpenStack. Open Networking offers: Freedom of choice at every layer – choice of hardware, choice of operating system, choice of applications Choice of hardware and software elements to best fit your applications Leverage same compute management infrastructure on network switches. Ability to leverage the same team for multiple workflows - Lower OpEx The resources of a rich ecosystem Modern data center tools for automated operations

Vendor independence &
automation enable rapid
innovation, operational
cost savings, and scalable,
affordable capacity.
“By 2017, Web-scale IT will be an architectural approach
found operating in 50 percent of global enterprises…”
