SMB protocol (Server Message Block)
Server Message Block (SMB) protocol is network communication protocol for providing shared access to files, printers, and serial ports between nodes on a network. (SMB is also known as Common Internet File Systems (CIFS)).
Cloud File Data Migration and SMB
Unstructured data migrations to the cloud can be billions of (mostly small) files, which have significant overhead, causing data transfers to be slow. In addition, SMB protocol workloads, which can be user data, corporate shares, electronic design automation (EDA) and other multimedia files, etc., are bring even more challenges since the SMB protocol requires many back-and-forth handshakes, thereby increasing traffic over the network. Another challenge with SMB cloud data migrations is wide are network (WAN) latency. Network file protocols like SMB are extremely sensitive to high-latency network connections, which are unavoidable in WAN migrations. Bandwidth is also often limited or not always available, causing file data transfers to become slow, unreliable and difficult to manage.
