there's a way to move 20kW of heat away from a rack if your normal CRAC is
moving 10kW (it depends on that basic air flow), permitting six blade servers
in a rack. panduit licensed this tech from IBM a couple of years
Hi folks:
This is my first posting to this email group. If I am at the wrong place for
what I'm asking, I humbly ask for the your collective indulgence.
I am having a problem with a service order with ATT and I am getting nowhere
with their sales organization. My repeated inquires go unheeded

It allows you to market your operation as a data center. If
you spread it out to reduce power density, then the logical
conclusion is to use multiple physical locations. At that point

Understandably, some applications fall into a class that requires very-short
distances for the reasons you cite, although I'm still not comfortable with the
setup you've outlined. Why, for example, are you showing two Ethernet switches
