I run proxmox and a trunas VM.
- TrueNAS is on a virt disk on a NVME drive with all the other VMs/LXCs
- I pass the HBA through to TrueNAS with PCI passthrough: 6 disk Raid z2. this is ‘vault’ and has all my backups of hone dirs and photos etc
- I pass through two HDs as raw disks for bulk storage (of linux ISOs): 2 disk Mirrored zfs
Seems to work well
I use AdGuard in my OpnSense firewall.
Why do you want a server on proxmox and NAS? or have I read this wrong?
