One of the key questions for Innovium is whether it will be able to deliver TeraLynx. The chip, which is “very close” to tape out, is expected to sample in the fall and be in volume production early next year.
“In the last decade, several companies have defined and announced switching products, but execution missteps have proved costly in terms of market adoption,” said Wheeler of Linley Group.
“We believe that we have a decent time-to-market lead and an optimized architecture — others will need to go to 7-nm technology,” said Khemani.
Key to Innovium’s success so far was attracting two top engineering managers who helped design Broadcom’s Trident and Tomahawk switches — Puneet Agarwal and Mohammad Issa. Khemani and Agarwal were former classmates at the Indian Institutes of Technology who stayed in touch over the years.
After leaving his post as chief operations officer at Cavium in 2013, Khemani was working as an investor. He found out that both Agarwal and Issa were interested in forming a startup. Khemani “sought funding on the basis of our resumes … [and we] got funded without having a product defined,” he said.
Broadcom sued the startup a few months after it was formed in early 2015. The companies settled in May 2016 for undisclosed terms, leaving open the question of whether Broadcom might sue again on patent infringement once a product becomes available.

Growing public cloud services from the likes of Amazon, Facebook, and Rackspace, along with web giants such as Facebook are driving the need for Ethernet speed. Innovium’s Khemani said that he expects large data centers to consume well over half of the world’s servers in the next few years.
In a step toward winning that business, the startup named to its advisory board Yuval Bachar, a principal engineer for LinkedIn’s data centers. Bachar previously led network system design at Facebook.
“Innovium’s TeraLynx is a game-changer in the industry … [that can be used] in all tiers across the data center from top-of-rack to core fabric,” Bachar said in a press statement, citing the chip’s port and buffer density.
Other members of the startup’s advisory group included Pradeep Sindhu, founder and vice chairman of Juniper Networks, and representatives of software companies Metaswitch and VMware. Software partners are key at a time when data centers are driving networking functions off of ASIC-heavy routers to x86 servers.
Overall, analysts are upbeat about Innovium’s chances.
“Whereas every other new entrant is merely matching Broadcom on bandwidth, Innovium is leapfrogging Broadcom with a next-generation design. If they execute to schedule, they should have a significant lead in enabling single-lane 50 GbE as well as 200 GbE and 400 GbE,” said Wheeler of Linley Group.
“The Ethernet Switch Market in the data center is undergoing rapid transition as the demand for higher speeds by cloud providers is pushing the market quickly toward 400G,” said Alan Weckel, founder and technology analyst at 650 Group. “12.8-Tbits/s fabrics will start getting deployed by mid-2018 and become commonplace in the data center by the end of the decade as the cloud becomes a larger segment than the enterprise market.”
