Use fans to keep server racks cool - Data & Server Racks

Businesses need to ensure they keep their server racks at the optimum temperature - and fans may provide the answer.

According to rack manufacturer Toughrack, individual units can be cooled simply by the use of fans in the cabinet.

Some cabinets have in-built fan systems, otherwise fan trays can be installed, the firm explained.

"Fans generate airflow but to ensure the most effective cooling, it may be necessary to install blanking panels to control airflow and to use good cable management practices to prevent blockages," the firm stated.

"To facilitate airflow, some racks incorporate ventilation panels in their doors and sides or else have mesh doors. In some, the side panels can also be removed where security is not an issue."

Toughrack suggested using the hot aisle, cold aisle system, which sees servers arranged in rows facing the same direction.

Cool air is taken in at the front and the hot air is expelled from the rear and directed towards the input of the cooling unit, the firm explained.

It highlighted the importance of server room monitoring, noting that temperature seriously affects server performance and humidity can be "particularly harmful".

"It is best to seal your server room so that no air can escape or enter the room," Toughrack stated.

"This facilitates better control over both temperature and humidity; greater control equates to less risk of damage."
