Power Management in Colocation Data Centers: From Uncoordinated to Coordinated (Project Link: Here)

Research Overview

  • Power Management in Colocation Data Centers [PDF]

    Power-hungry data centers have been massively expanding in both number and scale, placing an increasing emphasis on optimizing data center power management. While the progress in data center energy efficiency is encouraging, the existing efforts have dominantly centered around owner-operated data centers (e.g., Google). Another unique and integral segment of data center industry  — - colocation data center, simply called “colocation”, which is the physical home to many Internet and cloud services – has not been well investigated, which, if still left unchecked, would become a major hurdle for sustainable growth of the digital economy.

    In sharp contrast with owner-operated data centers where operators have full control over both computing resources and facilities, colocation rents physical space to multiple tenants which individually control their own physical servers and power management, while the colocation operator is mainly responsible for facility support (e.g., providing reliable power and cooling). The uncoordinated power management, resulting from the colocation operator's lack of control over tenants’ servers, invalidates many of the existing power management solutions for owner-operated data centers, thereby making colocations’ operation highly inefficient.

Short Bio

Shaolei Ren received the B.E. degree in Electronic Engineering from Tsinghua University in July 2006, the M.Phil. degree in Eletronic and Computer Engineering from Hong Kong University of Science and Technology in August 2008, and the Ph.D. degree in Electrical Engineering from University of California, Los Angeles, in June 2012. Since August 2012, he has been with Florida International University, where he currently holds a joint appointment of Assistant Professor in the School of Computing and Information Sciences and the Department of Electrical and Computer Engineering.

Dr. Ren directs the Sustainable Computing Group at FIU. His research centers around cloud computing and data center resource management, with an emphasis on sustainability. He received the Best Paper Award at the 8th International Workshop on Feedback Computing, the Best Paper Award at IEEE International Conference on Communications in 2009, and was selected by IBM T. J. Watson Research as one of the 10 Emerging Leaders in Multimedia and Signal Processing in 2010.
