TrueNAS Overview

Two TrueNAS SCALE boxes anchor the lab's storage and a handful of always-on services:
| Box | Role | LAN | VLAN 20 (MGMT) |
|---|---|---|---|
truenas (main) |
Primary storage, TFTP/PXE, backups | 10.10.10.3 | 10.10.20.3 |
truenas-dr |
DR/secondary storage, Vault container, Docker Apps (ADO agent) | 10.10.10.4 | 10.10.20.4 |
Both are dual-NIC hosts sitting directly on two subnets, which is exactly the configuration that needs the policy-based-routing fix described in Networking Gotchas — read that before troubleshooting anything that looks like a stalled transfer or an unreachable service on either box.
Official download
TrueNAS SCALE downloads — always current; check the release notes for ZFS/Docker/Apps changes before upgrading either box.
Why two boxes
truenas-dr isn't just a backup target — it also runs live services (Vault's unsealer
container, the self-hosted Azure DevOps agent) via TrueNAS SCALE's Docker/Apps support,
which truenas (main) does not. See Services for the full breakdown of
what runs where.
Storage protocols in use
See Services for the full list (NFS, SMB, iSCSI, FTP, AFP, rsync) and what each one is actually used for — this lab runs an unusually wide protocol spread because it's deliberately mirroring the kind of heterogeneous storage consumers a real platform team has to support (Unix compute, Windows clients, VMware datastores, camera NVR ingest, and Apple clients).
