| Abstract | In high energy physics and seismic physics, mass data is produced. Recent years, the ability of processor makes a rapid growth due to the development of IC technology, while the IO speed of data storage growth slowly, especially for the magnetic media based hard disks which is widely used for mass data storage. Traditional ways to increase the performance of hard disks show low efficiency due to the data couples of working disks. This paper presents a novel method of how to build a high-parallel and high-efficiency disk cluster. All the data is divided into different datasets, the datasets are stored into different disks based on a data-oriented method to cut off the relationship of them. Each dataset can be accessed independently, so much hard disks can work together efficiently. A prototype experiment result shows with the joint of 23 hard disks the cluster can do 3680 IO transfers per second (IOPS). Comparing with the 161.16 IOPS for single disk, the average IOPS of the cluster is 160.02, only 0.7% performance decreases due to the parallelization. |

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.
