Questions & Answers
It's important to ensure that the server rack is properly cooled, and cold airflow is sufficient to prevent overheating and equipment failure. If you plan on buying a portable or in-rack air conditioner, and need to know how much cooling power you need, here are some helpful tips.
The amount of heat that a server rack produces depends on the type of equipment in the rack, the number of devices installed, and the workload of the equipment. As a general rule, a fully loaded server rack can produce anywhere between 4 and 20 kilowatts of heat.
