ENERGY LOSS MODEL FOR TIER 2 AND TIER 3 DATA CENTERS
Keywords:
Energy loss model, data center, energy efficiency, power distribution systemAbstract
Demand for energy for data centers has soared during the COVID-19 pandemic. In 2020, the demand for energy for data centers is around 1% of worldwide electricity consumption and will be 3-13% in 2030. Energy loss in data centers is the main focus of this research. An energy loss model has been constructed to investigate data center power distribution systems (PDS). The model found that the highest energy loss is from the power supply unit (PSU) of IT equipment and the uninterruptible power supply (UPS). A server upgrade to PSU 80 PLUS Titanium reduces energy loss by around 2.7 times when compared with a normal PSU. These amounts of energy loss affect long-term operating expenses over the course of the data center’s lifetime. Moreover, this research compares PDS of Tier II and Tier III data centers to measure energy loss. The research results demonstrate that Tier III data centers lost approximately 1.782 times more energy through PDS than Tier II data centers.
