Answer

  • The Server Message Block (SMB) protocol version used for file-sharing operation is determined during the negotiation process.
  • It depends on the highest version supported by both the clients and the servers.
     
  • This table describes the protocol used with the default server/client configuration:
Protocol Version First Client Version First Server Version Data ONTAP Version
SMB 1.0 Windows XP Windows Server 2003 All
SMB 2.0 Windows Vista Windows Server 2008 7.3.1 and later; 8.x
SMB 2.1 Windows 7 Windows Server 2008R2

8.1 clustered Data ONTAP;

8.1.1 7-Mode

SMB 3.0 Windows 8 Windows Server 2012 clustered Data ONTAP 8.2 and later
SMB 3.1 Windows 10 Windows Server 2016  ONTAP 9
