Aquantia is developing 10 gigabit per second ethernet product for use in datacenters, like a number of other companies we've recently reported fundings for, including Tehuti Networks, Chelsio Communications and BridgeWave (here, here and here).
The Milpitas, Calif. company has not yet released any products, and has so far only stated publicly that it is working with the 10GBASE-T standard, which uses copper twisted pair cables. The standard is a newer one, with products only slated to hit the market this year. It's expected to cost less for deployment and maintenance.
Pinnacle Ventures led the $26 million round, joined by previous investors Lightspeed Venture Partners, Greylock Partners and Venture Tech Alliance. Aquantia has taken two rounds to date, for a total of $41 million.
