[Beowulf] 'liquid cooled' racks

[Mike Davis]

Bruce,

I am investigating the APC Infrastructure and Liebert XDH systems for a 
new small (1000 sqft).

The benefits seem to outweigh the potential downsides. They include 
relatively easy n+1 capacity, tightly coupled cooling for efficiency, 
and containment to prevent air mixing. Virginia Tech has been using the 
Liebert XDV units as supplemental cooling for System X since it was 
installed. I believe that other top 100 installations are planned that 
will use the XDH.

Infrastuxture seems to be good on a price for performance basis because 
the units are modular and generic.
