Hello All, I'm just starting to think about building some mass-storage arrays and am looking to better understand some of the components involved. For example, the Supermicro SC826 series of systems is available with three backplanes: 1. SAS / SATA Expander Backplane with single LSI SASX2

You're right, from the documentation it definitely should work. Still, it doesn't. At least not in Solaris 10. But i am not a zfs-developer, so this should probably answered by them. I will give it a try with a recent OpneSolaris-VM and check, wether this works in newer implementations of zfs.
