MAPFS-DAI, an extension of OGSA-DAI based on a parallel file system

Since current applications demand access to a huge volume of data, new and sophisticated I/O systems are required. Several mass storage systems have been developed from different institutions to access their own data repositories. These systems expose native interfaces not interoperable among them. In order to deal with this requirement, OGSA-DAI has emerged to provide a uniform access to data sources. However, this initiative is not focused on the performance of the I/O operations. This paper describes MAPFS-DAI, an approach which tries to combine both ideas: performance and interoperability.
