I have seen Do I need to leave gaps in a standard server rack? and my question is similar but different:
I have several rack servers (DELL 2850 mostly) but do not have a rack structure. Can I simply put one server on the top of another without having cool issues? (a pile of servers without putting them in a rack cabinet, just on the top of a desk one above the other)
I know rack cabinets allow some space between servers, even if you dont have gaps between them. What I am asking is just to put one on top of the other, with no vertical space at all.
Thanks
