Will a hot row facing a wall cause hot spots?

I am currently in the process of planning a new pod in my datacenter. To maximize space, my plan calls for a hot row which faces a wall. Will this cause hot spots, or will it act similarly to hot row containment, and actually improve flow of return air?

Thanks. We'll let you know when a new response is added.

The wall would just stop it from the heat going away straight back further. You would need a parallel flow of air movement in the “hot aisle” so the “hot air” won’t just sit back against that wall.
You would need to have vents to suck in that hot air, otherwise it would just sit there, and then start going off in random directions as more hot air is forced on it.

    I would say this depends largely on the rest of the airflow in the room. Pressure differentials, convection, and a number of other factors will determine if that air will sit there and heat up your hardware or move along. Hope this helps! -Schmidtw
