Feedback Green Control for Data Centers Autonomy

Abstract

Recently, reports show that ICT has significant increases in power consumption. Owing to that, an urgent call on greening the computing and communications technologies is rising, especially on service hosts (data centers). However, researches are undertaken toward reduce the power consumption in data centers, these works are following different approaches to achieve different power optimization goals such as cost and performance. For example, approaches are following thermal control concepts while others following resources sharing. These approaches leak of the concept of the co-existing of quality assurance and green energy suppliers. In this paper, we proposed a green extended autonomy feedback control for data centers. In addition, we proposed a hybrid policy approach to engage co-exists of the two determinants in system autonomy. Our solution was test on a web-based application and proof (compared to autonomic-only systems) that it captures the co-existing and adapts the data center operation accordingly.
