Data Center Cooling


A few decades ago, the amount of data produced each day was so limited that even a small chip was considered sufficient to store it but as the technology progressed, the amount of data produced each day, increased so drastically that huge reservoirs were required to store it. That was the time when data centers came into play. A data center is a huge room or at times, a whole building, which is equipped with computing devices hence providing a huge storage for the ever-increasing amount of data.

Since the data centers are a home for computer systems, servers and other IT resources and all these devices produce a large amount of heat while running, therefore, a proper cooling method is needed to be employed in order to maintain the normal temperature of the data center. In this article, we will talk about the basic components of a data center cooling system, the traditional data center cooling techniques, data center cooling challenges and finally, we will talk a little about Proactive Support.

The Basic Components of a Data Center Cooling System:

The normal operating temperature of a data center should be between 21 and 24 degree Celsius. This temperature is maintained by the following basic components of a data center cooling system:

●       Infrastructure: This component consists of all the equipment that is required for cooling the devices at the data center such as air conditioners, cooling towers etc.

●       Management: This component manages all the cooling equipment and their interaction with the data center’s resources.

●       Monitoring: This component monitors the temperature inside the data center all the time and notifies whenever the temperature increases or decreases beyond the prescribed operating temperature range.

The Traditional Techniques of Data Center Cooling:

Following are the two most common data center cooling techniques, which have been in use for many years:

➢        Air-Based Cooling: In an air-based cooling system, hot air from the data center equipment is allowed to escape through an outlet and then cold air from the surroundings is allowed to enter the data center in order to normalize the temperature inside the data center.

➢        Water Based Cooling: In a water-based cooling system, cold water is passed through steel coils that are wrapped around each data center equipment. This, in turn, causes the data center equipment to cool down thus maintaining the ideal temperature of the data center.


Data Center Cooling Challenges:

Now we all know the importance of data center cooling systems but let us have a look at some challenges that we face while employing an appropriate cooling mechanism in our data centers:

●       The humidity in the air can cause rusting in the data center equipment. Therefore, the air must be purified from humidity before allowing it to enter the data center in an air-based cooling system.

●       Although, the water-based cooling systems are very efficient but it is also a well-established fact that water is a very good conductor of electricity. Therefore, care should be taken so that the coils do not leak and the water does not come in direct contact with the data center equipment.
