 Another illustration of Google's obsession with efficiency comes through power supply design. Power supplies convert conventional AC (alternating current--what you get from a wall socket) electricity into the DC (direct current--what you get from a battery) electricity, and typical power supplies provide computers with both 5-volt and 12-volt DC power. Google's designs supply only 12-volt power, with the necessary conversions taking place on the motherboard. Another illustration of Google's obsession with efficiency comes through power supply design.

 Older Google facilities generally have higher PUEs, he said; the best has a score of 1.12. When the weather gets warmer, Google notices is that it's harder to keep servers cool. Older Google facilities generally have higher PUEs, he said; the best has a score of 1.12.

 Most people buy computers one at a time, but Google thinks on a very different scale. Jimmy Clidaras revealed that the core of the company's data centers are composed of standard 1AAA shipping containers packed with 1,160 servers each, with many containers in each data center. Most people buy computers one at a time, but Google thinks on a very different scale.

 Operating at Google's scale has its challenges, but it also has its silver linings. For example, a given investment on research can be applied to a larger amount of infrastructure, yielding return faster, Hoelzle said. Operating at Google's scale has its challenges, but it also has its silver linings.
