can you further specify what you mean by NFS? Do you mean Network File System (NFS)?
The VxWorks kernel we use in LabVIEW Real-Time does not yet support NFS or CIFS network filesystem support.
You can use TCP/IP or other protocols to stream data or ftp for file sharing.
Is there any plan to support NFS in the near future. I read some article about "Big Physics" in America where they used this feature with a custom BSP on a cRIO system.
It would be very helpful to use sbRIO/cRIO standalone. The measurement data should be written without any host into a file on a file server.
