MoSMB is built as an SMB2/SMB3 (server message block smb protocol) user mode server stack designed to run crucial enterprise workloads such as Enterprise File Server, Microsoft Hyper-V and SQL Server. It is built to be feature-rich, fully compliant, light-weight, low footprint and proprietary license bearing. By leveraging MoSMB, storage providers can expand their NAS offering to include SMB/CIFS protocol with a dramatically decreased Time to Market and increased First Time Right chance. MoSMB architecture is plugin based and modularized. This facilitates easy integration of MoSMB into storage systems (file, object or block) including clustering infrastructure by using well- defined integration APIs. MoSMB is written in ANSI C 99 for maximum portability and integration with diverse storage stacks. It is available for all popular flavors of Linux and also FreeBSD. It is also architected such that it is relatively constraint-free and can utilize the underlying platform’s capabilities and resources to the utmost for maximum performance and scalability
