You can use the following shared file systems for file sharing:
Network file systems such as CIFS (SMB) on Windows or Network File System (NFS) on UNIX. Although network file systems are not designed for high-performance computing, they can work well for sequential file access.
Clustered file systems. Clustered file systems provide a group of nodes with high-bandwidth file access, as well as a unified namespace for files and directories. Clustered file system performance is similar to a direct-attached local file system.
If you have the High Availability option, use a clustered file system.
Proper configuration and tuning can be critical for small grid performance. You can also configure mappings and sessions to avoid the intrinsic limitations of shared file systems.
