GridNFS is a collection of NFS version 4 features and minor versions with supporting databases and tools that enables NFSv4 to integrate with emerging Grid technologies to provide petabyte scale file service for the Grid.
NFSv4 is the IETF standard for distributed file systems that is designed for security, extensibility, and high performance. The challenges of authentication and authorization in GridFNS are met with X.509 credentials, which can bridge NFSv4 and the Globus Security Infrastructure, allowing GSI identity to be used in access control lists on files exported by Grid NFS servers. The challange of data location in the Grid is met by the NFSv4 global file namespace which can join enterprise desktop and cluster file space.
Petabyte scale can be acheived through a combination of tuning the NFSv4.0 enterprise file service, and the emerging NFSv4 Parallel NFS (pNFS) minor version.
