Data Center design.

I'm wondering if there are any mailing lists or other resources concerning building, designing, and maintaining Data Centers. I've found some vaguely helpful resources from netsearches, but so far I've been pretty disappointed with the amount and level of the available information. Are there any books? Any respected "authorities"? Is everyone learning as they go, or are all of the new Internet DC's being built by old-school mainframe/datawarehouse types? Any related information would be appreciated. Use private email unless you enjoy being spanked by the nanog.police (I'm sure someone will think Data Centers have nothing to do with network operations). -Brian
