Background
In a common data center, the ratio of the energy efficiency ratio is PUE (IT equipment power consumption/total power consumption); but this ratio is not suitable for liquid cooling systems.
Because the fan is removed from the liquid cooling system, the server nodes are soaked or semi-soaked in the liquid, and all energy consumption for supplying power to the server nodes is used for consumption of the IT equipment, the liquid cooling energy efficiency ratio of all the liquid cooling systems is 1 if the mode is used.
The method for determining the liquid cooling energy efficiency ratio of the liquid cooling system by using the energy efficiency ratio in the common data center has the following problems:
on one hand, the energy efficiency ratio between the liquid cooling systems cannot be compared;
on the other hand, the efficiency of energy consumption associated with liquid cooling cannot be explained.
As can be seen from the above, for the liquid cooling system, since some of the deployment methods do not include a fan in the server and do not require external refrigeration, the conventional energy efficiency ratio does not use determination of the liquid cooling energy efficiency ratio of the liquid cooling system.
