The Fibre Channel feature is available to Enterprise-licensed High Availability (HA) and non-HA systems. Any Enterprise system, equipped with the required fibre channel hardware can implement this feature.

This article provides instructions for VMware VCenter ESXi. If you are using a different platform for your block share backups, use the documentation for that platform for alternative instructions for the ESXi process documented in this tutorial. .

When setting up iSCSI fibre channel for the first time:

A multiprotocol share exposes the same dataset over both SMB and NFS simultaneously, so Windows clients and Unix-like systems can access the same data without duplicating storage. This is most useful in mixed environments where some clients lack an SMB client or where a Linux workload and Windows clients need shared access to the same files.

Connecting to and using an iSCSI share can differ between operating systems.

This article provides instructions on setting up a Linux and Windows system to use the TrueNAS iSCSI block share.

In this section, you start the iSCSI service, log in to the share, and obtain the configured basename and target. You also partition the iSCSI disk, make a file system for the share, mount it, and share data.

TrueNAS lets users expand Zvol and file-based LUNs to increase the available storage in an iSCSI share.

To expand a Zvol LUN, go to Datasets and click the Zvol LUN name. The Zvol Details widget displays. Click the Edit button.

Users of TrueNAS 24.04 (Dragonfish) or newer can migrate data from a third-party NAS solution onto TrueNAS using the Syncthing Enterprise application. The Syncthing Enterprise application can mount remote SMB shares in a manner that preserves relevant metadata. TrueNAS 24.10 (Electric Eel) also adds migration support for SMB alternate data streams (ADS), used to store application-specific metadata.

TrueNAS Enterprise

Third-party data ingest is available to TrueNAS Enterprise customers with TrueNAS 24.04 (Dragonfish) and newer deployed, as well as the appropriate applications license. TrueNAS Enterprise Support staff are available to assist with deploying the Syncthing Enterprise Application and migrating data. Please contact TrueNAS Enterprise Support to learn more and schedule a time to deploy the app and begin migration.

If you have not added iSCSI shares to the system, the iSCSI widget shows text stating general information about the block (iSCSI) share targets until a share is added.

If you have not added NFS shares to the system, the NFS widget shows text stating general information about the Unix (NFS) shares until a share is added.

After setting up storage on your TrueNAS, it is time to begin sharing data! There are several sharing solutions available in TrueNAS, but in this article we discuss the options to create the share and dataset from the Shares screens.

TrueNAS provides three types of sharing methods:

TrueNAS can serve object storage over the Simple Storage Service (S3) protocol. S3 is the application programming interface (API) that Amazon Web Services created for its object storage service. Many storage products and applications now use the S3 API as a standard way to store and retrieve data, and products that support it are often called S3-compatible. TrueNAS provides S3-compatible object storage on the local system and does not use Amazon services.
