I’m agree with @Toyoo, if your already have this complex setup, it’s fine to reuse it also for the storage node.
But if you built it only for Storj (what we are not recommend to do anyway), then it’s not performant but resource-hungry solution (I mean the performance/costs ratio here), running the node even as a pod on TrueNAS Scale would be more efficient and can use zfs dataset directly than the current one with a zvol (which will effectively disable cache in my opinion), then using iSCSI as a transport, then also NTFS and Windows VM (high resource consumption) on ESXi (another server). Just a heavy waste of resources especially if you know that the node can run even on an OpenWRT router: Running node on OpenWRT router?
