| Abstract | With the rapid development of information construction around the world, it needs special storage system to provide a stable, reliable, safe data storage service. This paper develops a Dual-Controller system which adds the hardware level redundant relative to Single-Controller system, so it has high stability and reliability in the level of disk and controller. It can satisfy the requirements of storage service stability of higher industry. The Dual-Controller system uses the special heart module between the controllers for communication. So when the system is running, one controller is always getting the mirror controller's state, which helps to detect the fault when the mirror controller is fault. We create the CACHE module to maintain two types of data of CACHE and MIRROR. The experimental result shows the performance of Dual-Controller system is almost the same with the Single-Controller system, but the Dual-Controller system won't loss the data and can continue to provide data services. |

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.
