Yes, it was one of their &quot;secret sauce&quot; things that they kept top secret for a long time. Fundamentally, if you change the question from &quot;putting computers into data centers&quot; to &quot;how can I build a building sized computer?&quot; it changes the way you think. Microsoft has been somewhat late to that particular party, both Facebook (perhaps with some Google knowledge &quot;leakage&quot;) and Amazon have done a good job of internalizing this view point.<p>It scares the crap out of data center providers because they know they can&#x27;t really innovate like this effectively. I tried to get Equinex to consider building Open Compute racks in a different style of co-location setup but never got anywhere with them.
