Mailing list/group for datacenter facilities folks
Just wondering, Is anyone aware whether there is already an active mailing list/group for datacenter facilities folks to discuss power, cooling, physical infrastructure, etc, etc...? thanks, -Drew

I would love to be a part of this list if there is one!!! Cooling is not as easy as just pumping cold air into a room.

Perhaps there should be a DC track at NANOG? One of the reasons I have not gone in years. I have much knowledge and experience to share, but no one to share it with.

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.

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.

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