Implementation of replication methods in the Grid environment

Abstract

Data replication methods are often used in Grid environments for improving the access time and data protection level. Dynamic replication allows the system to automatically create and delete replicas in order to follow dynamically changing system parameters and user access patterns keeping the performance high and resource usage in reasonable limits. In this paper we present the replication aspects of the Virtual Storage System developed within one of the grid projects. We also present results from replication tests done in a real grid environment. © Springer-Verlag Berlin Heidelberg 2005.
