Oracle HSM (originally known as: SAMFS - Storage Archivation Management + QFS)

support of off-laid/staged files. SMB offers "off-line" flag for off-laid files

so the SMB client can behave accordingly to such file-status:

 - explorer do not create thumbnails to avoid staging of all files in browsed dir.

 - explorer display a small "hand-watch" symbol in the corner of file-icon

note: MacOS X ignore the "off-line" flag in SMB protocol.

Originally promoted into the community by:

 https://bugzilla.samba.org/show_bug.cgi?id=5780

...but during the SAMFS version change also the licensing conditions

has changed so the community rejected to adopt the SAMFS support.
