Given that you're still using one array for everything, I would just use
whatever is most convenient. Although AoE has some apparent advantages, I am
not a fan as it lacks the security that iSCSI has native. I would probably
export an NFS directory or use iSCSI and export a file using fileio mode.

OTOH, your network between the two is pretty secure :) Use AoE...

I wouldn't even consider Samba, why muddy the waters sharing data between Linux
hosts emulating a non native Linux protocol. That's just silly?
