What's New in Fusion SMB 3026.4

The Fusion SMB 26Q2 major release is now available and contains our latest features for new use cases and scenarios. It builds on our commitment to enterprise production services you can trust.

Tuxera creates two major releases of Fusion SMB annually, in the 2nd and 4th quarter of each calendar year. There are also two maintenance releases, in the 1st and 3rd quarter. Below is a summary of what's new, with links to further details and configuration guidance.

SMB over QUIC​

Fusion SMB now offers SMB over QUIC, a third alternative to RDMA and TCP. QUIC is an always-TLS 1.3 encrypted protocol that adds the reliability, congestion control, and error correction that traditional UDP lacks.

SMB over QUIC works on networks that often block port 445 over TCP — such as the Internet and DMZs. You can use SMB over QUIC inside a network for added safety, but also at the edge of your network, in cloud tenants, and as a hybrid solution joining everything together.

Because QUIC is just a different transport, applications and users require no new code or training.

Encrypted LDAP bind password storage​

Fusion SMB now supports storing the LDAP bind password in an encrypted keytab file instead of as plain text in tsmb.conf. The password is encrypted using the AES-256 key wrap algorithm (RFC 3394) and stored in a separate file defined by the ldap_bind_keytab configuration parameter. Use tsmb-passwd --set-ldap-passwd to create the keytab file. The previous ldap_bind_pw configuration parameter is still supported for compatibility.

Support for macOS Spotlight with dehydrated files​

Fusion SMB now supports Apple's macOS Spotlight feature being used with Fusion SMB shares where files have been dehydrated by nearline storage solutions such as IBM Tape.

Previously, a user browsing and searching files with Spotlight would lead to offline files being rehydrated from tape unnecessarily with a variety of SMB file server products. With Fusion SMB as the remote file system provider, this rehydration no longer occurs, leading to:

  • A much faster user experience
  • Lowered wear on tapes
  • Lowered disk consumption on the file server
