#'s around hotter air
As I understand the "cooling" for the M1000e our energy smart design enables a better performance per watt, but yields "more" heat to the hot isle in a datacenter compared to HP chassis.
Logic dictatates that this heat will be adequately "re-cooled" as it makes its way back to the cold isle and back throught the front of the chassis.
That said, do we have documentation of the heat being "adequatley re-cooled"?

Now that doesn't mean that air coming out the back is not going to be hot. Of course it is, and will be hotter than anything you compare from a "regular" rack sever because of the density.
The issue becomes one of total datacenter design. We do an excellent job of removing the heat from the chassis and the rack, but now what are you and your customers going to do about that heat that is released ? Since every datacenter has the potential to be designed different, there are many different ways to "re-cool" the air, as you say. Luckily Dell is helping in that area as well and we have several partnerships that can help. One is from Liebert and you can get more info from this page --> http://www.delltechcenter.com/page/Dell+Liebert
David Moss and his team from Dell Thermal Solutions Engineering have also done some great work on showing how we can solve the air-recirculation problem. Basically you want to keep the hot air back in the hot aisle, and keep it from creeping around to the front of the rack and getting sucked back into the servers. You might want to ping him for more info on this topic.
Hope this helps.

This hotter, dryer, slower air is exactly what you want to reduce energy consumption. I think Scott pointed to a great paper on this subject. It explains why you want this in a data center.
Hope this helps.
