| Abstract | Traditionally storage has been purchased and attached to a single computer system. Such storage is accessible only through the computer system to which it is locally attached. In the last 10 years, especially in corporate data centers, storage is being increasingly purchased independent of the processors, and independently managed and administered. Because of the standardization of disk IO protocols, storage can be easily shared amongst various heterogeneous processors running various applications. The shared storage is accessed over a network interconnecting the processors to the shared disk subsystem, known as the storage area network - a network on which processors send IO calls to virtual disks. It is the task of the storage controller to manage the mapping of virtual disks to physical disks, a task known as storage virtualization, similar to memory virtualization of processors. The storage virtualization layer has been exploited to provide diverse storage functions. If a reasonable prediction of IO workload can be made, the storage virtualization layer could optimize the mapping of physical disks to virtual disks to satisfy applications' IO response time requirements. In this paper, we tackle the problems of moving data in a storage hierarchy under both capacity/performance constraints and on-demand resource provisioning constraints |

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.
