To meet the growing demand of Online Services, data centers consume
billions of KWh electricity every year, and the number is expected to
double in the next 5 years. A typical data center is operated
conservatively and as a result almost half of the energy consumption
goes into cooling, and power distribution, and idled servers. In this
talk, I summarize a number of research efforts in the Data Center
Genome project, which takes a data-driven approach to data center
energy management, leveraging networked sensing and control
technologies. We have designed and deployed wireless environmental
sensors to monitor heat distribution in server rooms and
software-based services to estimate server power consumption. We
tackled the challenges of reliable wireless data collection, time
series compression and analysis, and static/dynamic resource
management. The findings are used to advance the way equipments are
provisioned, loads are distributed, and systems are operated in
datacenters.
