A place having many computers and servers at a single location is a data center. Every data center needs a cooling system to perform efficiently; therefore, CRAC (Computer room air conditioning system) is necessary for keeping the overall temperature regulated. As computers are becoming more compact, the power consumption and heat-generating capacity of the systems increase. Therefore most efficient cooling systems are needed to keep everything stable. Earlier, when few computers and heat generated were less, merely pumping the cold air in the space was sufficient. But, now, as the data centers’ capacity and the systems’ size increase, a continuous cooling system is required to keep things more relaxed in the surrounding environment.
CRAC unit or computer room air conditioning represents an air conditioning data center system necessary for keeping the overall temperature regulated.
Now let we see how CRAC unit works:
Here is CRAC unit example:
Here is an example of Server Room Air Conditioning Failure:
