Commodity-based distributed file system that federates local disks of compute nodes It can be shared among all cluster nodes and clients –Just mount it as if it were high-performance NFS It provides scalable I/O performance wrt the number of parallel processes and users It supports fault tolerance and avoids access concentration by automatic replica selection

As the 1st step, bi-directional file transfer between gLite and Gfarm using GridFTP. Problem: GridFTP authentication (delegation) cannot be directly passed to Gfarm file server. GridFTP-DSI (Data Storage Interface) has been used for integrating Gfarm API into GridFTP.
