Abstract

Data centers’ demand response (DR) program has been paid more and more attention recently. As an important component of data centers, multi-tenant data centers (also called “colocation”) play a significant role in the demand response, especially in the emergency demand response (EDR). In this paper, we focus on how the colocation can perform better in the EDR program. We formulate the “uncoordinated relationship” in the colocation which is the key problem affecting energy efficiency, and propose a reward system to motivate tenants to join the EDR program, and a truthful strategy is developed to ensure the authenticity of tenants’ information. For achieving the overall coordination, we integrate tenants’ resources to increase the colocation’s resource utilization and optimize the whole colocation’s energy efficiency, then devise two algorithms to solve the actual resource migration and integration problem. We analyze the complexity of allocation model and two algorithms. Experimental results show that our solution is practical and efficient.
