There's an interesting analysis here on what could be a major new technology from Google.
It's no secret that for some time the company has been using its own class of x86 motherboard, supposedly optimized for large data center operations. Now, it seems, those devices are about to hit the open market.
Rackable Systems, which built a good chunk of the Google boards, recently introduced the CloudRack designed for large-scale operations. The next step is said to be a series of 12V-only motherboards featuring two servers per board, exactly the same design elements released on a Google white paper earlier this year.
Among the advantages would be the elimination of multiple power converters and other energy-consuming hardware that accompanies mixed-voltage boards. One drawback, however, is that the board might not have the appropriate power levels for other devices on the rack.
Google may also be working on a new kind of clustering interconnect to rival 10 GbE or Infiniband, although the source for that tidbit admits he's been out of the loop since 2006.
