Abstract | The upsurge1 in information technology (IT) has brought significant changes in people's lives. As an important part of the IT industry, Data Centres (DCs) have been rapidly growing in both the number and size over the past 40 years. Around 30% to 40% of electricity delivered into DCs are used for space cooling, thus leading to very inefficient DC operation. To identify the routes for reducing cooling loads of DCs and introduce the energy efficient cooling technologies (e.g. dew point cooling) into DCs practice, a dedicated investigation into DCs across Europe has been undertaken, with particular attention given to the capacity, space scale and energy load condition of the data centres. It is found that DCs can be generally classified into four types in terms of the power capacity, i.e., super, large, medium and small sized types. The energy saving potential in 4 types of DCs when managing cold air supply at the room level, row level, and rack level is studied and the cooling demand based on the simulated dynamic IT load is determined. In addition, Annual electricity consumption for the two kinds of air conditioning systems was compared to further explore the energy saving in DCs. This research therefore formed a foundation for the follow-on works in developing the energy efficient cooling system design. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
