Policy-based Autonomic Management in Data Centers

点击翻译按钮获取中文摘要

As data centers and systems grow, become more heterogeneous, support increasingly diverse applications and computing environments, system administrators face daunting challenges in managing the systems and applications in order to meet operational requirements, e.g., as embodied in service level agreements (SLAs). Concomitant with these challenges, data center operators face increasing costs of power for both computing and environmental systems as well as increasing environmental legislation. Consequently, operators must try to optimize several competing objectives: minimize power consumption, reduce emissions/carbon footprint, manage thermal output, meet performance and availability constraints, ensure security, etc. Addressing these challenges is multifaceted, requiring: novel hardware approaches, improved software, conservation strategies, and increased automation of data center management.
