There’s, probably, no IT administrator who hasn’t heard of SMB3 (Server Message Block). is an application-layer network protocol, developed by Microsoft mostly to provide shared access to the files, and allowing communication between nodes. SMB has been designed as a tool for the creation of a DOS-based network file system, but Microsoft took the initiative and renamed SMB into CIFS later on (Common Internet File System) and continued further developing it. The second version – SMB 2.0, has been introduced in Windows Vista with a wide range of new features, thus it became clear that Microsoft was working hard to improve this protocol.

Now, to SMB3. It’s an improved version of the previous Server Message Block protocol that Microsoft introduced as one of the key features in Windows Server 2012 operating system. SMB3 comes with a significant number of new capabilities like SMB Transparent Failover, SMB Encryption, VSS for SMB file shares, SMB Direct (SMB over RDMA) and SMB Multichannel. SMB Multichannel allows file servers to use multiple network connections simultaneously, therefore increasing performance and adding one more level of Fault Tolerance within the networking layer.
