| Abstract | Summary form only given, as follows. Today, the storage technology is strongly required for cloud computing, big data, and so on. The size of data used in business and science is drastically increased. According to the concept of internet of things, many sensor devices are widely spread in the world and generate large amount of data. These data are aggregated to a few large-scale data center. In this way, data center has a model of reality. On the other hand, storage technology is rapidly developing. For example, the capacity of HDD was increased in recent years. SSD and other flash memory based fast devices have been developed and are popular. Such storage device technologies are used to build data centers for big data. In such large scale storage, large amount of disks are used. The cost of storage is determined by the number of disks. It is usually proportional to the number of disks. However, even if the reliability of single disk is high, the reliability of a whole system is decreased because it is reversely proportional to the number of disks. Therefore, it is important to improve the reliability of storage. In order to increase the reliability of storage, several reliable technologies are applied to storage. For example, RAID is familiar with commodity server. In cloud, P2P based replication is used. Generally, the performance of replication is better than RAID. However, the replication drastically decreases the capacity efficiency of storage. In the design of storage, we should not estimate only performance but also must consider the reliability and capacity efficiency. In this talk, I will present important points for designing the effective storage. In my Lab, we have developed Virtual Large Scale Disks (VLSD) toolkit for constructing large scale storage. I will show several evaluations that are measured by VLSD as a storage simulator. |

| Resource Type | Synopsis |
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.
