Replica Selection on Co-allocation Data Grids
Data Grid supports data-intensive applications in a large scale grid environment. It makes use of storage systems as distributed data stores by replicating contents. On the co-allocation architecture, the client can divide a file into k blocks of equal size and download the blocks dynamically from multiple servers by GridFTP in parallel. But the drawback is that faster servers must wait for the...
متن کاملReplica Management in Data Grids
Providing fast, reliable and transparent access to data to all users within a community is one of the the most crucial functions of data management in a Grid environment. User communities are typically large and highly geographically distributed. The volume of data that they wish to access is of the order of petabytes and may also be distributed. It is infeasible for all users to access a singl...
متن کاملResponse Time Optimization for Replica Selection Service in Data Grids
Problem Statement: Data Grid architecture provides a scalable infrastructure for grid services in order to manage data files and their corresponding replicas that were distributed across the globe. The grid services are designed to support a variety of data grid applications (jobs) and projects. Replica selection is a high-level service that chooses a replica location from among many distribute...
متن کاملFragmented Replica Selection and Retrieval in Data Grids
Data Grids support data-intensive applications in wide area Grid systems. They utilize local storage systems as distributed data stores by replicating datasets. Replication is a commonly used technique in a distributed environment. The motivation of replication is that replication can improve data availability, data access performance, and load balancing. Usually a complete file is copied to ma...
متن کاملReplica traffic manager for data grids
Replication is used in data grids to improve the efficiency of user requests. One or more copies of files are stored on storage components, replicas, in the data grid. Currently, users send their requests directly to these replicas. There is no control over a request once it leaves the user. The focus of this paper is controlling workload traffic at data grid replicas, by managing the flow of r...
