Irvine, Calif.-based Solarflare Communications announced the availability of network adapters that, because of the company’s low-power SFC9000 chipset, offers high-speed networking for servers while helping to trim energy costs. And not just for any servers either, but systems that drive virtualized and/or cloud environments thanks to its hardware assisted virtual I/O acceleration for VMware, Microsoft Hyper V and Citrix Xenserver.

According to Solarflare, it has the distinction of offering the industry’s lowest power “single port 10GBASE-T adapter, at 7.9 watts, and the lowest power dual port 10GBASE-T adapter, at 12.9 watts, versus competing solutions at 20 watts or more.” Of course, those savings add up when you start filling up those server racks.

Prices start at $619 for the SFN5152F Single-Port 10GbE SFP+ Midrange Server Adapter and go up from there.
