Hmm I did a google search for this Marvel controller and suprisingly found this:
http://www.sun.com/bigadmin/hcl/data/systems/details/2306.html The details includes this same controller chip as the heart of the machine for the SATA disks. So am I to believe this is meant to be used for ZFS and is the expected configuration to be Raid10 {mirrored paired sets} only? This message posted from opensolaris.org
