The chipmaker Innovium bagged $77 million in a Series D funding round. It brings Innovium’s total financing to over $160 million. Investors in this latest round included Greylock Partners, Walden Everbright, Walden Riverwood Ventures, Paxion Capital, Capricorn Investment Group, Redline Capital, S-Cubed Capital, and Qualcomm Ventures.

The new funding will be used to drive production of Innovium’s Teralynx 6.4 Tb/s and 12.8 Tb/s data center Ethernet switch chips.

“We are actually shipping samples and prototypes of silicon, which is being used to build switches,” said Amit Sanyal, Innovium’s VP of marketing.

He added, “We offer network silicon that is targeted exclusively at data centers.” The company sells to three segments: 1) large cloud customers; 2) original equipment manufacturers that make switches; and 3) white box manufacturers. The company mainly competes with Broadcom, the primary provider of network switch silicon with its Trident and Tomahawk franchises.

Barefoot Networks is also competing for switch chip market share with its programmable chips. Innovium’s CEO Rajiv Khemani said, “Our chip is programmable as well. It means, in the network, the chip is capable of supporting new protocols or innovations without a silicon spin. We have a programmable chip at 12.8 Tb/s today.”

And Cavium also targets the data center switching market with its Xpliant Ethernet switch family.

Asked why Qualcomm’s venture arm would invest in Innovium, Khemani said, “Qualcomm has been looking at the data center market, and I think that’s aligned with their vision.”

Innovium first emerged on the scene in December 2014. And by May 2016 it had raised $50 million and indicated it was working on Ethernet switching chips to deal with east-west traffic in data centers.
