I'm very interested to hear about your results with HAST/ZFS combo > because I have a possible use case. I've only used it in testing via VirtualBox so far. Our intended use is to create a fail-over storage network (1 server at building A, 1 server at building B, connected via gigabit fibre) for a virtualisation setup. In testing inside VirtualBox, it works nicely. Just waiting for our fibre link to go live to test it on real hardware. :) -- Freddie Cash fjwcash@gmail.com
