Free cooling technologies for data centers: energy saving mechanism and applications

Solar Energy and Free Cooling Potential in European Data Centers

Energy efficiency has become one of the key issues for data center operators in recent years. Significant power and consequent cost savings are perceived to be attainable and are also considered to be mandatory due to environmental aspects and for sustainable development. Use of economizers and free cooling is currently one the most prominent ways to make data centers more efficient. Besides ef...

Energy-saving self-configuring networked data centers

In this paper, we develop the optimal minimum-energy scheduler for the dynamic online joint allocation of the task sizes, computing rates, communication rates and communication powers in virtualized Networked Data Centers (NetDCs) that operates under hard per-job delay-constraints. The referred NetDC’s infrastructure is composed by multiple frequency-scalable Virtual Machines (VMs), that are in...

Energy Efficient Storage Technologies for Data Centers

An impressive amount of work has been done to date on improving the electrical efficiency of various data center components. The data storage industry has begun to see the fruits of this effort, with increased power supply and fan efficiencies. However, storage presents other significant opportunities for energy conservation, through various types of capacity optimization, that are not captured...

Evaluation of Energy Storage Technologies and Applications Pinpointing Renewable Energy Resources Intermittency Removal

Renewable energy sources (RES), especially wind power plants, have high priority of promotion in the energy policies worldwide. An increasing share of RES and distributed generation (DG), should, as has been assumed, provide improvement in reliability of electricity delivery to the customers. Paper presented here concentrates on electricity storage systems technologies and applications pinpoint...
