Power Management In Data Centers -- Prof. Mor Harchol-Balter

Prof. Mor Harchol‐Balter is the Associate Department Head of Computer Science at Carnegie Mellon University. Data center power consumption continues to increase at an alarming rate, doubling every 5 years, and already exceeding 100 billion kilowatt‐hours annually in the U.S. alone. What is most frustrating is that much of the power being used is wasted. Servers are only busy 30% of the time on average, but are left on, utilizing 70% of peak power when in the idle state. This talk argues in favor of dynamic capacity provisioning (turning servers on and off as needed) with the goal of saving power.
We will present implementation results, on a multi‐tier data center with key‐value workload, as well as
