NVIDIA has acquired Cumulus Networks. Financial terms were not disclosed.
Cumulus, which was founded in 2010 by JR Rivers and Nolan Leake, developed a Linux-based operating system for network switches. The company signed licensing deals with Dell, HPE, Mellanox, and Lenovo. Cumulus is also known for its pioneering work with the open network install environment (ONIE) project. Investors in the company included Andreessen Horowitz, Battery Ventures, Sequoia Capital, Peter Wagner and 4 of the 5 original VMware founders. Cumulus is based in Mountain View, California.

NVIDIA said the combination of its recently-acquired Mellanox division with Cumulus Networks will enable a new era for accelerated, software-defined data centers.
NVIDIA's target is to "innovate and optimize across the entire networking stack from chips and systems to software including analytics like Cumulus NetQ, delivering great performance and value to customers."
Mellanox has been collaborating with Cumulus since 2013. Mellanox Spectrum switches already ship with Cumulus Linux and SONiC, the open source offering forged in Microsoft’s Azure cloud and managed by the Open Compute Project.
SoftBank Group Corp. agreed to acquire ARM Holdings Plc in an all-cash deal valued at £24.3 billion. (US$32.4 billion), or 1,700 pence per ARM share, and representing a premium of 43% over the closing price on preceding trading day. The deal would be Softbank's largest to date.

The companies said they intend to double employee headcount in the UK over the next five years.

ARM is the leading developer of RISC processor designs that are widely licensed for use in smartphones, tablets, laptops, desktops, embedded systems, and, increasing, servers. The company posted 2015 revenue of £968.3 million. A total of 14.8 billion ARM-powered SoCs shipped in 2015, up from just over 12 billion in 2014.
SoftBank will fund the acquisition with cash on hand and a load from Mizuho Bank of Japan.

ARM will be an excellent strategic fit within the SoftBank group as we invest to capture the very significant opportunities provided by the “Internet of Things,” stated Masayoshi Son, Chairman and CEO of SoftBank.
Regarding strategic rationale, both companies said they see big opportunities ahead with IoT.
