TL;DR: This work presents a novel approach to model the energy flows in a data center and optimize its operation that can reduce both the recurring power costs and the use of non-renewable energy by as much as 60% compared to existing techniques, while still meeting the Service Level Agreements.
Proceedings ArticleDOI
Data center demand response: avoiding the coincident peak via workload shifting and local generation
TL;DR: Two algorithms for data centers by combining workload scheduling and local power generation to avoid the coincident peak and reduce the energy expenditure are developed by developing two algorithms via numerical simulations based on real world traces from production systems.
Journal ArticleDOI
Data center demand response: Avoiding the coincident peak via workload shifting and local generation
TL;DR: Developing two algorithms for data centers by combining workload scheduling and local power generation to avoid the coincident peak and reduce the energy expenditure and the results show that using workload shifting in combination with local generation can provide significant cost savings.
Proceedings ArticleDOI
Minimizing data center SLA violations and power consumption via hybrid resource provisioning
TL;DR: The results show that the approach can provide up to 35% savings in power consumption and reduce SLA violations by as much as 21% compared to existing techniques, while avoiding frequent power cycling of servers.
Proceedings ArticleDOI
SLA Decomposition: Translating Service Level Objectives to System Level Thresholds
TL;DR: This paper presents an approach that combines performance modeling with performance profiling to create models that translate SLOs to lower-level resource requirements for each system involved in providing the service, eliminating the involvement of domain experts.
