A Data Center performance comparison analysis between Tier III architecture and a CCHP alternative solutions

Nowadays, the server´s capabilities are on the increase at or beyond the rate of performance predicted by Moore´s Law. The IT services, with the advent of cloud computing, become an increasingly critical part of everyday business activities, and then the power consumption of today´s data centers skyrockets due to the rapid growth of their scales and the high required reliability levels. These aspects aggravate, significantly, the operational cost of data centers. The Uptime Institute´s Tier Classification System affords a reliable method to compare typically unique, customized facilities based on expected site infrastructure performance. During the last decades many Data Centers architecture solutions have been investigated in order to reducing the overall costs. The Combined Cooling, Heating, and Power (CCHP) systems have the potential to decrease carbon emission and air pollution and to increase resource energy efficiency significantly. To mitigate the negative loop between the IT service growth and power consumption and to evaluate the data center power infrastructure energy impact, on equivalent availability requirements contests, the aim of this paper is to propose a set of equivalent reference schemes for developing and comparing PUE evaluation. The construction of this set is made by comparing a standard TIERIII topology, in agreement to Uptime Institute gradient definition with CCHP solutions.
