Answer

Maximum file size for CIFS shares and NFS exports

Write Any Where File Layout (WAFL) maximum file size limit

Beginning with Data ONTAP 5.1, files sizes of up to 8terabytes(TB) can be created. Data ONTAP 7.0 allows a maximum file size of 16 TB. NetApp recommends a maximum file size of 500 gigabyte(GB), to maintain optimal performance and to keep traditional backup/restore times at a minimum.

Note:

  • File sizes are also bound by the amount of physical disk space available on the filer, and the supported capacity on the controller
  • Regardless of the version of Data ONTAP in use, some protocols support files only up to a certain size:
    • NFSv2 has a maximum file size of 2 GB
    • NFSv3 allows for 64-bit file offsets, which is larger than the WAFL 16 TB maximum
    • Microsoft NTFS has a 16 TB file size limit in Windows 2003
    • CIFS protocol allows for 64-bit file offsets, but most likely the WAFL limit will be reached beforehand
  • Certain client operating systems may also limit the file size they can access, regardless of protocol

For the latest information regarding maximum file size, see the 'Storage Limits' section of the 'Logical Storage Management Guide' for your release of Data ONTAP:
