Research on key indicators and regional comparison of green data centre

With the continuous growth of the amount of information, the scale of green data centre is becoming larger and larger, and it is more and more widely used, the construction of green index system of green data centre has become a key problem to be solved urgently. This paper studied on the basic index system of green data centre, with the help of PUE, CEI and TCO index analysis, it is made in depth analysis of the factors affecting the green index of the green data centre, factor analysis is used from nine aspects such as annual average temperature, annual precipitation, air quality index, earthquake belt and fixed assets of information transmission enterprises, the mathematical model of evaluating the operation advantage of green data centre is constructed, to made quantitative analysis and evaluation classification, and according to the calculation, the comparison results of green data centre development area are obtained.
