ABSTRACT
The rack/server supply air/water has an influence on the IT power consumption and also on the cooling system consumption. Since recently, it used to be that the CPU was running at a certain frequency, and as long as the maximum permitted CPU frequency was not reached, it will be continue running at maximum speed. The experimentation was done using a thermal budget power management in which the CPU was used as much as possible while ensuring not overheat of itself. The IT equipment is the main contributor to electricity consumption and heat production of a Data Centre. The effects of gaseous pollution and particles on different types of equipment failures are well documented. Power factor is the ratio of real power to apparent power, where real power is the capacity of the circuit to perform work, and apparent power is the product of the current and voltage of the circuit, which also includes current affected by reactive compounds.
