The fastest and most scalable
enterprise SMB server on Linux

Fusion File Share by Tuxera™ is a high-performance, scalable distributed file system for providing access to unstructured or file-based data over a network. It brings support for Microsoft’s Server Message Block (SMB) protocol to public cloud platform-as-a-service (PaaS) offerings, software-defined storage (SDS) solutions, high-performance computing (HPC) applications, and enterprise-grade network attached storage (NAS). Fusion has all the latest security and SMB capabilities to suit even the most demanding organizational needs.

Our SMB software is a highly reliable alternative to Samba and other SMB server implementations, especially where scalability and performance are critical requirements for your products.
