| Abstract | Parallel file systems commonly distribute a file across multiple file servers with a fixed-size strip, so that the data access can be served through multiple devices simultaneously, which is similar to RAID 0. The default data layout works well in traditional homogeneous storage systems, but as the Solid state disks (SSD) are conduct into storage system, the data layout of heterogeneous parallel storage systems need to reconsider in order to get a better performance. In this paper, we propose a strip level data layout strategy for heterogeneous parallel storage systems (SLDP), which find the optimal strip configurations for each solid state disk file server node (SNode)and mechanical hard disk drive file server node (HNode), according to data access pattern, along with the consideration of the limitation of SSD space, use variable strip size to reorganize the data layout of storage systems. the main idea is let the key regions of file get the optimal strip configuration, which can obviously improve the system performance, and rest part of the file are distributed according to the SSD free space threshold, which may reduce the system performance, SLDP can find a data layout that makes the improvement is much bigger than the reduction, so that to get totally better performance of the heterogeneous storage system. Experimental results show that the SLDP is feasible and can improve system performance. |

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.
