Fajar, thanks for pointing out Oracle Appliance. Gonna have a look at that.
I'm testing Nexentastor now, yet it fails to start or detect on my test HW.

Walter, my question is about XCP, so it it only 2 storage nodes, XCP
itself has more nodes than that.
Also we have already tested Asterisk, works fine for several month now.
