This paper reports on a study of energy consumption for data storage in data centres. Unlike previous estimates, which have been extrapolations of broad energy usage within the data centre, we take a bottom-up approach. We show that the growth in energy consumption can be mitigated somewhat by adopting a more aggressive policy of data archiving on long-term, low-energy, “cold” storage; or more ideally purging data of little or no future value.
A recently published report by CEET has identified access networks, not data centres, as a growing & significant threat to the sustainability of services delivered from the cloud. This is because more people are accessing cloud services via wireless networks.
This article presents our perspectives of the 5G technologies with two major themes: Green and Soft. By rethinking the Shannon theorem and traditional cell-centric design, network capacity can be significantly increased while network power consumption is steady or even decreased
The next disruptive trend arising from ICT technologies will be a societal phase transition as we move to a fully connected world in which a vast number of machines and devices distributed around the planet collect, store, process and exchange information to enhance our daily lives - The Internet of Things. It has been predicted that the number of such devices could be over 100 billion virtually ...
