"With Boston, the ARM-based solution (1535 servers; 1.6 racks; 2 switches; its power consumption at 13kW) can offer 40 percent lower total cost of ownership, while it can be implemented in 61 percent less space, he claimed, compared to the X86-based solution (1997 servers; 4 racks; 44 switches;37kW)."
Effectively, the statement implies less space and less power consumption per server compared ARM to x86. I don't quite understand the difference of number of switches - 2 vs 44.
There is a movement of 64 bits ARM server. Whether it will take over x86 based server, only time can tell. Cloud based service providers may be able to shorten the time if the risk is properly handled.
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.
