Power limits in data centers: what can we expect from improving energy efficiency and refreshing servers?

Résumé

Ten years after the drafting of the Paris Agreement, the objective to reduce greenhouse gas emissions by half by 2030 seems difficult to reach. The impact of ICT technologies is growing year after year. Data centers have a large impact in this domain. As a lot of research is focused on improving energy efficiency of data centers, one could ask if this improvement would suffice to reduce greenhouse gas emissions. To study the impact of the energy efficiency on the long term, we propose to model a data center that has a limited power capacity and is regularly refreshed with new servers, more energy-efficient than the previous ones, to cope with its workload. Our results explore various growth rates for the load, and the energy efficiency and show that without reduction of usage of data center resources, the improvements in energy efficiency will not be not enough to reach the Paris Agreement's objective.
