The document discusses the DC4Cities project, which aims to make data centers more environmentally sustainable and adaptive to renewable energy availability for smart cities. The project will develop techniques for dynamically consolidating virtual machines and turning off servers to reduce power consumption based on renewable energy levels. It will also integrate data centers with smart city energy management systems. The DC4Cities approach was tested in Trento and through a solar energy experiment at an HP facility in Milan, Italy.

DC4Cities Rationale
Running a data centre at high levels of renewable energy sources is the great challenge
Ecomondo 2014 @ Rimini
Certain Services require DCs to be close to users
Smart Cities require Services, hosted by DCs
Smart Cities need Eco- friendly DCs
Europe needs new metrics for DC energy efficiency
DC4Cities:
an environmentally sustainable data centre for Smart Cities

DC4Cities: let DCs become energy adaptive
Ecomondo 2014 @ Rimini
Eco-friendly DC energy policies needs to be capable of
adapting the power consumption to the availability of renewable energy
being adapted to the requests received by the Smart City Energy Management authority
