SMB 3.0 (Server Message Block 3.0)
SMB 3.0 (Server Message Block 3.0) is a protocol that provides a way for a computer's client
applications to read and write to files and to request services from server programs in a computer
network.
SMB 3.0 was originally introduced with Windows Server 2012 as SMB 2.2. It was renumbered to 3.0
to reflect the additions in the new release compared to the previous version, 2.1.
SMB 3.0 implementation is included with Windows
Server 2012.
