A RAID will only hurt you with all in one. Do you have hardware passthrough with Hetzner (I presume you're with them, from the sound of it) on ESXi? > > 2: should i mirror the boot drive for the VM? > > If it were my money, I'd throw ESXi out the window and use Illumos for > the hypervisor as well.

Plus, you'll be able to set up a ZFS mirror on I'm very interested, as I'm currently working on an all-in-one with ESXi (using N40L for prototype and zfs send target, and a Supermicro ESXi box for production with guests, all booted from USB internally and zfs snapshot/send source). Why would you advise against the free ESXi, booted from USB, assuming your hardware has disk pass-through? The UI is quite friendly, and it's easy to deploy guests across the network. > the data pair and set copies=2 on the rpool if you don't have another > disk to complete the rpool with it.
