File and Storage System Support
SMB/CIFS File sharing for Microsoft Windows, Mac OS X, and Unix/Linux (using Samba client)
systems using SMB or CIFS
NFS File sharing for Unix/Linux systems via NFS v3
FTP/FTPS File sharing via FTP. Secure sessions supported via FTP over SSL.
Journaled file system XFS
Unified file locking Provides common file-locking mechanism that allows simultaneous, multiprotocol access to
common shares by Windows/Mac (CIFS), Unix/
Linux (NFS), and FTP.
Virtualization Supports virtualization of RAID sets across multiple chassis (requires at least 1
NSS6000/NSS6100 on the same network). Supports up to 4 exported RAID sets per master
unit.
