DOLFIN

DOLFIN is an initiative supported by the FP7 Program from the European Commission. The main goals of the project are to improve energy efficiency in data centres by optimizing Virtual Machine distribution in servers, and to stabilize the grid using demand response techniques or even providing energy to the grid from local sources or storage.

DOLFIN aims to significantly contribute towards improving the energy efficiency of Data Centres and stabilizing of Smart Grids, a holistic approach, across networks of Data Centres and Smart Grids. Today, most DCs are part of computing and storage clouds, offering their customers Virtual Machines (VMs) as a virtual operating environment. DOLFIN will model, monitor, and measure energy consumption and enable seamless, autonomic migration of VMs between servers of the same DC or across a group of Energy-conscious, Synergetic DCs, aiming to:

Optimize the overall energy consumption by dynamically changing the percentage of active versus stand-by servers and the load per active server in a DC;
Stabilize the Smart Grid energy distribution, under peak load and increased demand, by dynamically changing the energy consumption/ production requirements of the local DCs.
