| Abstract | Today's storage systems and database systems are highly complex and configurable, which makes storage management intricate and costly. One critical aspect of storage management, particularly in large storage infrastructures (e.g. cloud storage), is to determine which application data sets to store on which devices. With a mechanism which has the ability to predict the performance of the storage device for any given workload, administrator could automate this process. Therefore, storage device performance prediction has become a critical aspect of self-managed storage systems. To this end, we propose a general smoothing hybrid model (namely SRT-SVR) which combines regression tree (RT) and support vector regression (SVR) to accurately model storage device performance. With this new method, the advantages of the two techniques (i.e. RT and SVR) are completely amalgamated to obtain a more accurate and efficient model without compromising prediction time. In addition, we propose a new workload characterization method which can describe request more accurately. Experiments show that SRT-SVR method and the characterization method used in the storage device modeling can produce more accurate and stable predictions than RT and SVR. |

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.
