When setting up a server rack is it a good idea to leave some room in between servers or can you stack them on top of eachother? Also should longer servers go below shorter servers for cooling purposes?

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

Most servers are designed to be right on top of each other. If they don’t have vent holes on the top they can be stacked without any space between them. The cool air comes in the front, so short servers on top shouldn’t matter as the hot air is forced out the back.
You should try to put your heavier servers towards the bottom of the rack though, just to keep the CG as low as possible. And dont forget those metal feet for the racks. So that the rack doesnt fall over you when you pull out a server from the top third of the rack.

    In hot/cold aisle configurations, hot air could be allowed to mix with cold air to some degree, which usually would occur near the top of the racks, in which case it would be wise to put hotter equipment at the bottom of the racks, where cold air has less chances (and time) to become hot because of hot/cold air mixing.
