@TheDragon I actually have no idea how the new SDN works 馃槅 but knowing Proxmox it's built on top of Linux standard tools...
my reasons for using LVM rather than #ZFS:
* I don't have ECC memory
* lower memory & CPU requirements
* lower complexity
* not doing any type of redundancy yet because I don't have money for the necessary hardware
* transferable learning since I can use LVM elsewhere where ZFS is also not gonna be used
