چکیده
A data gridd is a collectionn of geographically dispersedd storag e resources over wide area network.. The goal of data gridd system is too provide a large virtual storage framewor kk withh unlimitedd power throughh collaborationn amongg individuals,, institutions,, andd resourc es.. Inn this study,, we first review a number of data gridd services suchh as,, too just name a few,, metadata service, data access service,, andd performance measurement service.. We t hen investigate various techniques for boosting the performance of data grid, andd these k ey techniques have fallen intoo becomes one of the prime concerns inn gridd computing,, we review twoo int eresting issues of security inn data grid.. Finally andd importantly,, we have identifiedd five inte resting openn issues,, andd pointed out some potential solutions too the openn problems..

Design of a Framework for Data-Intensive Wide-Area Applications
Applications that use collections of very large, distributed datasets have become an increasingly important part of science and engineering. With high performance wide-area networks becoming more pervasive, there is interest in making collective use of distributed computational and data resources. Recent work has converged to the notion of the Grid, which attempts to uniformly present a heterog...
متن کاملApplication of Big Data Analytics in Power Distribution Network
Smart grid enhances optimization in generation, distribution and consumption of the electricity by integrating information and communication technologies into the grid. Today, utilities are moving towards smart grid applications, most common one being deployment of smart meters in advanced metering infrastructure, and the first technical challenge they face is the huge volume of data generated ...
متن کاملA New Job Scheduling in Data Grid Environment Based on Data and Computational Resource Availability
Data Grid is an infrastructure that controls huge amount of data files, and provides intensive computational resources across geographically distributed collaboration. The heterogeneity and geographic dispersion of grid resources and applications place some complex problems such as job scheduling. Most existing scheduling algorithms in Grids only focus on one kind of Grid jobs which can be data...
متن کاملA Parallel Data Storage Interface to GridFTP
Most of the grid projects are characterized by accessing huge volumes of data. For supporting this feature, different data services have arisen in the “grid” world. One of the most successful initiatives in that field is GridFTP, a high-performance transfer protocol, based on FTP but optimized for wide area networks. Although GridFTP provides reasonably good performance, GridFTP servers keep co...
متن کاملData Management of Triple Quorum Replication (TQR) for Data Grid
Grid computing is essentially distributed computing over wide-area networks that often involve large scale resource sharing among collaborations of individuals or institutes. Computational Grids address computationally intensive applications that deal with complex and time consuming computational problems on relatively small data sets, whereas Data Grids address data intensive applications that...
