TrueNAS SCALETrueNAS SCALE Version Documentation
This content follows the TrueNAS SCALE 24.04 (Dragonfish) releases. Use the Product and Version selectors above to view content specific to different TrueNAS software or major version.

Component Naming

TrueNAS SCALE incorporates all the major TrueNAS CORE storage and sharing features with a web interface based on Debian GNU/Linux. Because SCALE shares the same UI as the FreeBSD-based TrueNAS CORE, users might notice there are similarities. However, SCALE does incorporate some differences, primarily in component naming.

TrueNAS SCALE automatically renames components, such as disks and interfaces, migrated from TrueNAS CORE, but does not modify the component Description. For example, the Name of an interface identified as igb0 in TrueNAS CORE is updated to eno1 after migration to TrueNAS SCALE, but the Description igb0 is retained. This difference is purely cosmetic and does not affect functionality.

Disks

TrueNAS Core utilizes a numerical listing of drives in a system.

ComponentNamingDrivesCore

TrueNAS SCALE uses a lettered format for drive identification.

ComponentNamingDrivesSCALE

SCALE still labels NVMe drives with a numeric value.

Interfaces

TrueNAS CORE enumerates interface names using interface drivers, such as igb for Intel devices, followed by a number. TrueNAS CORE Enterprise systems use ix followed by a number.

NetworkInterfacesScreen

TrueNAS SCALE enumerates interface names using PCI locations. By default, SCALE systems identify their network ports with eno or enp followed by a number.

NetworkInterfacesWidget

TrueNAS CORE identifies bonded interfaces or link aggregations with lagg followed by a number (lagg1). TrueNAS SCALE uses bond followed by a number (bond1).

See the TrueNAS Systems section for lists of the default port names for each platform.
