Within that concept, data center greening is of utmost importance at the moment since data centers are one of the most energy conserving elements. Data cen- ters are seen as the technology era’s black energy-swallowing secret. Reducing energy consumption at data centers can reduce carbon footprint efect tremendously. Not addressing the issue immediately will lead to signifcant energy usage by data centers and will hinder the growth of data centers. The call for sustainable energy efcient data center leads to venturing into data center green computing. The green computing concept can be achieved by using several methods adopted by researchers including renew- able energy, virtualization through cloud computing, proper cooling system, identifying suitable location to harvest energy whilst reducing the need for air-conditioning and employing suitable networking and information technology infrastructure. This paper focuses into several approaches used by researches to reduce energy consumption at data centers while deploying efcient database management system. This paper difers from others in the literature by giving some suitable solutions by looking into a hybrid model for green computing in data centers. INTRODUCTION The increase in need of data processing has led to a demand in obtainability for cheaper, faster, efficient and larger data management system. This has further introduced a significant problem in terms of en- ergy consumption and energy usage as mentioned in (Barroso. L.A, 2005). Since the trend of Internet Infrastructure is moving towards services-based computing, data center plays a key role in this new Green Energy in Data Centers Kanahavalli Mardamutu Quest International University Perak, Malaysia Vasaki Ponnusamy Universiti Tunku Abdul Rahman, Malaysia Noor Zaman King Faisal University, Saudi Arabia
