Why choose Fusion File Share by Tuxera

High-performance, scalable SMB server

With its modular and threaded design, our cutting-edge kernel-space deployment boosts I/O throughput, reduces CPU usage, has a low memory footprint, and enables fast, easy handling of multiple simultaneous connections to shared resources.

Extensive SMB-protocol support


Fusion File Share supports SMB 3.1.1 and previous versions (1.0, 2.0, 2.1). It works reliably with all SMB/CIFS protocols to ensure file-sharing interoperability across any network. We bring you comprehensive feature support including pre-authentication integrity, persistent handles, DFS support, VFS stacking, SMB over RDMA, SMB multichannel, shadow copy, and plenty more.


High availability


Fusion File Share can be deployed in Active-Passive mode over the distributed file-system clients to provide high availability and transparent failover of connections.


Simplified, secure data management

Fusion File Share provides capacity planning and management through quota support, as well as user audit and access log support, plus dynamic configuration of shares – with no re-start required. Furthermore, we offer support for multiple authentication providers, such as Windows AD services (Kerberos), LDAP (Lightweight Directory Access), NTLM, file-based local user and group databases, and more.

Easy integration with Windows environments

With Windows ACL/inheritance support, Fusion File Share integrates seamlessly with Active Directory (authenticate with KDC), while also working in Forest and trusted domains.

Optimized for Mac clients


Through rigorous testing, Fusion File Share ensures smooth performance and interoperability with the latest file access protocols used by Mac clients.
