Today’s big news has got to be Facebook’s unveiling of their Open Compute Project; open reference designs for highly efficient servers, and the data centers they sit in. There’s been a flood of coverage overnight, most of which has tended toward effusive praise for this move. Tom Raftery draws upon his own experience to take a good look at the green side of this story, and ZDNet’s Dan Kusnetzky and The Register’s Timothy Prickett Morgan are both quick to spot that a few server reference architectures will not change the world of server design overnight. Jesse Robbins, on the other hand, writes for O’Reilly Radar that “This is a revolutionary project, and I believe it’s one of the most important in infrastructure history,” broadly echoing Stacey Higginbotham’s take here on GigaOM. It may even be possible for them all to be right. One aspect of the news that struck me as particularly interesting was the apparent integration with OpenStack, with Rackspace CEO Lanham Napier commenting that “the Rackspace team has visited and studied Facebook’s next-generation data center, our engineers continue to collaborate, and we look forward to optimizing OpenStack for Open Compute.” It may not immediately change every server in every data center, but open computing on top of open hardware in open data centers cannot help having far-reaching implications for this industry. How will the incumbents respond?
