This arrangement places server racks in alternating rows where equipment fronts face each other to form cold aisles, while the backs create hot aisles. Cold air flows into the front of servers, and hot exhaust air exits through the rear. This setup achieves optimal airflow, which prevents hot and. The hot aisle /cold aisle data center layout was originated by IBM in 1992 and it is one of the oldest ways to save energy in the data center. A hot-aisle/cold-aisle layout enables cool air to flow through the aisles to the servers' front air intake and enables heated air to flow away from the servers' back exhaust to the air conditioner return ducts. This configuration is beneficial as it will conserve energy and lower cooling costs by directly managing air flow.
