Re: Computer room cooling

Those are cool; it's even more fun with a thermal imager:

Although, the price is rather restrictive on those.

I'd certainly get those breakers sorted out; you really have to wonder 
how hot those are on a nice summer day.  Wonder what "they" were 
thinking undersizing the feeder breakers?  Or is it more of a cascading 
failure situation?

There has been talk (for the past 9 years I've been here) about 
separating cold and hot aisles; to the point of covering the cold aisles 
forcing all the air through our cabinets in the datacenter, and having 
doors to all of the cold aisles.  I think I've seen some builds like 
that in the Telect or Chatsworth catalogs; but again, looks expensive.
Looks cool here:

But here's what we've got for now:
