Redundant and Load Balanced storage on FreeBSD?

Back from: https://unix.stackexchange.com/questions/81252/load-balanced-redundant-storage-on-freebsd How do I create a (Redundant and Load Balanced) Storage based on FreeBSD? - Storage should be located on (2 or more servers) providing Redundancy and Load Balancing (round robin) at the same time. - Storage needs to be accessible over network for other BSD machines as one folder (i.e. /storage) (NFS?). Any solutions are welcome, except for master-slave HAST and CARP. **Please don't post these: they are not related to this question.**
