Microsoft's James Hamilton often shares his notes from sessions at industry conferences on his Perspectives blog. This week he summarizes Jeff Dean's presentation at the Google IO event (which we briefly noted last month). In addition to his notes, James includes photos that Dean provided showing the evolution of Google's servers and racks from 1997 to the present. We've seen some of these before and noted them in the Google Data Center FAQ, but it's interesting to see the year-to-year progression. My favorite detail: the room fan blowing air onto the racks in the picture from 2000.
It's not always pretty, but the goal isn't to have the most handsome racks. "My general rule on hardware is that, if you have a viewing window into the data center, you are probably spending too much on servers," James writes. "The Google model of cheap servers with software redundancy is the only economic solution at scale."
