We just got a couple of HP DL360 G7's, and I notice it has vents on the top. More hot air seems to exit through these vents than it does anywhere on the back. All our servers in the past have always vented all the hot air through the back.
How are these servers with top vents supposed to be mounted? Everyone always says airflow is best by not leaving gaps on the rack, but it seems like a server right on top of it would receive a lot of heat.
