Is it possible to install Ubuntu Server (root) on a ZFS mirrored pool. E.g.
ssd1
- partition1
- partition2
ssd2
- partition3
- partition4
Then create a ZFS mirrored pool 'root' with partitions 1+3 and install Ubuntu Server on 'root' Second create a ZFS mirrored pool 'home' with partitions 2+4
Would it make more sense to have root on two separate disks?

The above should definitely be possible by following the "Root on ZFS" how-to; the only step which differs is the creation of the pool(s), after all. However, you should be aware of the fact that "non-ZFS partitions" (e.g., EFI) on said discs should be mirrored/kept in sync at all times as well in order to ensure that the system can still be booted if one of them fails; this has already been hinted elsewhere. You might want to check out Saverio Miroddi's "zfs-installer" repository on GitHub.
