LOL too funny guys.. I agree it has to do with air flowplus temps have to be just right.

Indeed... it's even easier than that. Cooling is as easy as making an entire room emit heat to the outside environment at an average rate that is consistently faster than heat transfer into the room from all sources. There are many ways of accomplishing that. One of the best ways is to put your room in an already cold environment, in contact with an excellent thermal conductor. For example... server room in the arctic region,at the bottom of some lake. Probably with all air removed from the environment, and a sound thermal medium such as oil pumped in in its place (make sure to use SSDs for all storage and no mechanical devices). -- -JH

Have found http://www.linkedin.com/groups?about=&gid=94108 to have some gems in it. I mention only because it's otherwise a case of YAML (that is, Yet Another Mailing List, not the logging format...) Of course, not everyone uses or likes LinkedIn. Mark.

RE: Mailing list/group for datacenter facilities folks
Perhaps there should be a DC track at NANOG? One of the reasons I have not gone in years.
