How to Keep Things Cool in Your Data Center: 11 Tips for Summer

Tip #3: If you have a raised floor, make sure that the floor grates (or perforated tiles) are located in front of where the hottest racks are. If necessary, rearrange or change to different floor grates so you match the airflow to the heat load. Be careful not to locate floor grates too close to the CRACs. This will "short circuit" the cool airflow immediately back into the CRACs and rob the rest of the room/row of sufficient cool air.

Tip #4: Check for floor openings inside the cabinets. Cable openings in the floor allow air to escape the raised floor plenum where it is not needed, and lowers the available cold air to the vents (in the cold aisles). Use air containment, brush-type collars kits to minimize this problem.
