NVIDIA, a company known for developing advanced chips for artificial intelligence and high-speed gaming applications has is making a concerted effort to go after cloud-based data-center customers by acquiring Cumulus Networks for an undisclosed amount.\nCumulus offers a Linux-based network operating system aimed at white box network gear users that supports large data-center, cloud and enterprise environments.\u00a0 Its Cumulus Linux offering supports over 130 different types of networking hardware.\nPerhaps its main hardware partner, however, is enterprise and cloud-network switch and adapter vendor Mellanox, which NVIDIA bought April 27 in a $7 billion deal. Mellanox and NVIDIA have developed open networking software together since 2013.\u00a0 Mellanox products are deployed in many of the world\u2019s fastest supercomputers and largest hyperscale data centers.\nNVIDIA Mellanox Spectrum switches already ship with Cumulus Linux and SONiC, the open-source offering for Microsoft\u2019s Azure cloud and managed by the Open Compute Project.\n\u201cWith Mellanox, the new NVIDIA has end-to-end technologies from AI computing to networking, full-stack offerings from processors to software, and significant scale to advance next-generation data centers,\u201d said \u00a0Jensen Huang, founder and CEO of NVIDIA at the close of that acquisition.\nThe Nvidia\/Cumulus combination expands that plan and enables the new era of the accelerated, software-defined data center, said Amit Katz, a vice president of Ethernet Switch at NVIDIA (who until last week had the same title at Mellanox) in a blog about the acquisition. With Cumulus, NVIDIA can innovate and optimize across the entire networking stack from chips and systems to software including analytics, he stated.\nThe result of both acquisitions is a stronger NVIDIA data-center hardware and software portfolio \u2013 its data center group made close to $1 billion in revenue in the last quarter and is growing at better than a 50% clip year-over-year\u00a0\u2013 that would bring it further into the enterprise-network and cloud-computing contest with the likes of Arista, Cisco, HPE, Dell EMC, VMware and others, many of which are also its allies. NVIDIA, Mellanox and Cumulus also have a big presence in some huge hyperscaler and big white-box customers, environments including Amazon, Google, Microsoft, Alibaba, and Oracle.\nOthers see the Nvidia Cumulus buy as a further \u00a0shrinking of open networking software options. For example, Arista recently bought open software-defined networking and cloud-software vendor Big Switch Networks for an undisclosed amount.\n"These recent acquisitions are evidence that the great disruption that was predicted around software defined and open networking a decade ago is happening right now. At that time, the companies that were most competitive in creating a viable open networking ecosystem were Cumulus, Big Switch and Pluribus Networks,\u201d said \u00a0Kumar Srikantan, CEO of Pluribus Networks in a statement.\n\u201cWith Big Switch and Cumulus being acquired by vertically-integrated system providers, Pluribus Networks is well-positioned to both remain independent and scale into a disruptive force as the market moves well beyond the original hyperscaler segment to achieve increasingly broad adoption in service provider and enterprise private cloud deployments," Srikantan stated.
