Well its logical isn't it ;-)
The rest of the story here.
According to the report; a major source of carbon emissions comes from the generation of electricity. The increasing demand for compute power, network bandwidth and storage capacity will increase the need for data centre power and cooling; economic uncertainty: doing more with less will drive it to consider ways to consolidate IT resources through virtualisation, increase utilisation of resources such as server cycles and storage capacities, eliminate redundancies where ever possible through de-duplication and single instance store, and reduce the working set of production data through the aggressive use of archive products.
An avalanche of unstructured data will be driven by RFID tags, smart cards, and sensors that monitor everything from heartbeats to border crossings. This will call for new types of archiving systems that can scale to petabytes and provide the ability to search for content across different modalities of data, predicts the company.
