[nflug] Server room A/C

[Darin Perusich]

You might want to try positioning the the power supply exhausts towards 
the return duck also. In our computer room we have a "hot isle" where 
the rear of our racks all face and all the return ducks are. This allows 
the heat from the exhausts to flow directly into the returns. When we 
repositioned the room in this manor it really cut down on how much the 
AC was being taxed.
