Abstract

ChinaGrid is a nationwide grid project supported by the Chinese government that aims at integrating massive heterogeneous resources distributed on the China Education and Research Network (CERNET). The ChinaGrid Supporting Platform (CGSP) is a grid middleware developed for ChinaGrid. It provides a series of system-level services for ChinaGrid, helps to build application portals and integrate grid resources, and supports the secondary development of grid services. Data Management Services (DMS) is a group of system-level services in CGSP for managing storage and data resources, supporting transparent data access, and guaranteeing high-performance data transfer on the grid. It consists of metadata management service, storage resource management service, replication management service, storage agent and transfer client. It offers the fundamental support for data access on ChinaGrid. In this paper, we introduce the design principle and implementation of DMS and its transfer scheme.
