Actually, none of this is necessary. The drive toward higher density per rack is a problem. By doing that cooling problems are made worse. I was at an event on data centers at the University of Illinois at Urbana-Champagne and a speaker from Microsoft discussed their findings. For one thing, space is not an issue, except in Tokyo and Hong Kong. Thus, you are better spreading the system out a bit.
Another thing they should consider, since they are using their own software, is another processor architecture. There are many very effecient processors based on the ARM and POWER architectures that might run their code faster and use a lot less power.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
