Contribution
This work introduces GRASP, a configurable SDN platform that dynamically schedules jobs based on renewable energy availability, addressing the challenge of renewable energy volatility in data centers.
Findings
GRASP effectively schedules jobs according to green energy availability.
The platform demonstrates adaptability with different scheduling algorithms.
Experimental evaluation confirms the practicality of GRASP in real testbeds.
Abstract
The transition to renewable energy sources for data centers has become a popular trend in the IT industry. However, the volatility of renewable energy, such as solar and wind power, impedes the operation of green data centers. In this work, we leverage Software Defined Networking (SDN) to build GRASP, a platform that schedules job requests to distributed data centers according to the amount of green energy available at each site. GRASP can be re-configured with different scheduling algorithms to address diverse factors such as amounts of instantly available solar power, wind power and CPU load of data centers. We utilize realistic green energy datasets from National Solar Radiation Database and evaluate GRASP in the GENI testbed; in addition, we create necessary GENI artifacts to repeat our experiment. GRASP can serve as a practical platform to test various job scheduling mechanisms for…
