The Server Message Block protocol (SMB) provides a method for client applications to read and write to files and to request services from server programs in a computers network. This protocol plug-in supports SMB/SMB2 protocols, as well as SMB 3.0 when SMB Multichannel is not in use. The SMB RDMA (Remote Direct Memory Access) implementation over the iWarp stack (incl. SMB Direct) is supported.
