Explanation:
There are often multiple rows of servers located in racks in server rooms. The rows of servers are known as
aisles, and they can be cooled as hot aisles and cold aisles. With a hot aisle, hot air outlets are used to cool the
equipment, whereas with cold aisles, cold air intake is used to cool the equipment. Combining the two, you
have cold air intake from below the aisle and hot air outtake above it, providing constant circulation. This is a
more effective way of controlling temperature to safeguard your equipment in a data center.
