High heat servers should typically be located at the bottom of a rack due to various thermal dynamics and airflow considerations within a data center. When servers generate heat, that heat naturally rises; therefore, placing the high heat servers near the bottom helps to manage the overall temperature more effectively.

In a rack environment, cooling systems often introduce cool air at the bottom of the rack. By positioning the heat-generating equipment lower down, the cold air can more effectively displace the hot air produced by those servers, leading to better cooling efficiency. This arrangement helps prevent overheating, improves server longevity, and enhances performance.

Distributing servers evenly throughout the rack or placing them at the top can inadvertently lead to localized hotspots or inefficient cooling patterns, which can negatively impact the performance and reliability of these high heat servers. Thus, strategically locating them at the bottom of the rack optimizes airflow and helps maintain an overall balanced temperature within the rack.
