Chris Hertel imageLast September, Microsoft unveiled version 2.2 of the venerable SMB (Server Message Block) file system protocol. The new version adds support for clustering, multi-channel communications, and RDMA transport — features that bring SMB into parity with current versions of NFS. NFS, of course, is specified in open standards while SMB is the last of the major proprietary network file system protocols still in common use. SMB is integrated into the Windows OS, is supported by virtually all NAS appliances, and is supported on Unix platforms by Samba and other implementations. It is quite possibly the most-used file system protocol on earth, yet the pool of SMB developers is relatively small, particularly when compared with NFS. This seminar will cover the structure and semantics of SMB and SMB2, including a description of state that must be maintained by clients and servers. Advanced features of SMB2, 2.1, and 2.2 will be described. Information will also be provided about the preliminary specifications which Microsoft has released for SMB v2.2 to allow third-party developers to start producing compatible products.
