Ensuring the efficient operation of server rooms is crucial for maintaining optimal performance and energy use. A key aspect of this is the orientation of servers. All servers should be aligned in the same direction to ensure they intake cold air from the front and expel hot air from the back. This prevents the hot exhaust from one server from being drawn into the intake of another, which can lead to overheating and inefficiency.
Proper placement of floor grills is essential for effective cooling. These grills should be installed only where cooling is necessary, specifically at the front of the servers. Avoid placing them at the exhaust side, in open areas, or in front of empty racks. It’s also important to balance the airflow through these grills. If the grills closest to the cooling units release all the cold air, the units further away will receive insufficient cooling. Positioning the grills near the front of the servers helps ensure that cold air does not bypass them and return directly to the cooling unit.
The space beneath raised floors should be kept free of objects and unused cables, as these can obstruct airflow. In server rooms with multiple rows of servers, hot exhaust from one row can be drawn into the next, increasing temperatures progressively. To combat this, arrange the server rows to face front to front and back to back. This configuration creates distinct hot and cold aisles, ensuring cold air is supplied only to the front of the servers and preventing hot exhaust from being drawn into another server.
Empty spaces in server racks should be filled with blanking plates to prevent warm exhaust air from recirculating. Additionally, fans within server racks can create a negative pressure region at the front of the server, which might draw warm exhaust air back into the server. Proper management of these factors is essential to maintain efficient cooling.
For existing data centers, cold aisle containment is an effective design strategy. This involves covering the cold aisle with a roof and sealing the ends with doors, creating a physical barrier to prevent air mixing and recirculation. In newer data centers, hot aisle containment is often used. Here, cold air fills the room while hot exhaust air is contained and separated by a ceiling, allowing it to be efficiently drawn back into the cooling units.

For efficient design, we need to ensure that all the servers are oriented in the same direction so that they all intake cold air from the front and exhaust hot air from the back. Otherwise, the exhaust from one server may be drawn into the intake of another server. We also need to ensure that floor grills are installed only where cooling is required, specifically at the front of the servers, not at the exhaust side, in open areas, or in front of empty racks.
Additionally, we must balance the airflow through the grills; otherwise, the grills nearest the cooling units will vent all the cold air, leaving the rear units with very little. The grills should be located near the front of the servers to prevent cold air from bypassing them and heading straight back to the cooling unit.
The area beneath the raised floor should be kept clear of objects and unused cables, as these can obstruct airflow. When several rows of servers are installed, a problem arises where the hot exhaust from one row is drawn into the next, causing the temperature to increase with each row, which is inefficient. To address this, we arrange the rows so that they face front to front and back to back. This way, we provide cold air only to the front of the servers, preventing hot exhaust from being drawn into another server, thus creating hot and cold aisles.
We also need to fill empty spaces in the server racks with blanking plates to prevent warm exhaust air from recirculating. Additionally, the fans in the server racks can create a negative pressure region at the front of the server, which may draw warm exhaust air down and recirculate it back into the server.
For existing data centers, one of the best designs is cold aisle containment, where the cold aisle is covered with a roof and the ends of the aisles are sealed with doors. This creates a physical barrier to prevent mixing and recirculation of air. Newer data centers may utilize hot aisle containment, where cold air fills the room and hot exhaust air is contained and separated by a ceiling, allowing it to be drawn back into the cooling units.
