Green Data Center Design of Udayana University

Abstract

Data center of Udayana University has not been integrated yet, so that it caused excessive power usage. Thus, a green data center system has to be implemented to make the power usage more efficient and eco-friendly. This study aims to find out the energy consumption of the data center in Udayana University; and to design the data center based on the criteria and standards of the green data center. Data of this study were collected by conducting a direct survey to the data center, interviewing the IT staffs and analysing the data center conditions. Then, green metrics calculations were conducted, including Power Usage Effectiveness (PUE) and Data Center Infrastructure Efficiency (DCIE) in addition to designing the green data center. This study reveals that the energy consumption in the data center is 104.231 w. in which the PUE calculation is 2,51 included as an inefficient categorization and the DCIE calculation is 39% that means the power usage efficiency is 39 %. Relying on the results, servers grouping is redesigned to minimize the cable usage and to make the checking activities easier, using a raised floor based on designed cooling systems, using 3 phase electrical systems to balance the load distributed, and redesigning the cooling system by using a row oriented cooling system and the cabling system in the data center. By designing the green data center in Udayana University, it is expected that the energy consumption could be significantly reduced and the efficiency could be increased.
