Their offerings provided increased flexibility, scalability, and cost-effectiveness for data center and enterprise networks. Cumulus Networks was acquired by NVIDIA in May 2020 and its technologies are now integrated into NVIDIA's networking solutions.
Served as the central hub for research and development, engineering, product management, sales, marketing, and corporate operations for its open networking solutions.
