"NAS storage systems often use their own software that only mimics Windows. Only Windows NAS systems are supported by QlikView."
/Troy Raney, Technical Support Engineer & Team Mentor
It is my understanding that NAS are no longer supported. It has to be a SAN and a Windows share.
Not really. It doesn't need to be a SAN (Storage Area Network). A NAS using Windows File System (NTFS) and SMB/CIFS for communication is perfectly fine, such as Windows Storage Server 2012 (or just a share on any Windows machine will do).
Important thing to remember is that other files systems except NTFS, such as ext2-4, ZFS, exFAT etc, are not supported.
Same goes for communication protocol. Only SMB/CIFS is supported, not NFS, AFP, NCP or similar.
