I've been unable to official documentation stating whether using a NAS file share (in my case, NetApp) as File Share Witness is supported for a Windows 2012 R2 Stretched Cluster. The cluster will support SQL 2012 AlwaysOn AGs. I've found unofficial blog posts from 3rd parties who have successfully configured a non-Windows file share as FSW, but need to know if this Microsoft supports this.
Thanks,
