Its not quite fake raid but its kinda in limbo.. I *much* prefer to use these cards in IT mode, which requires reflashing the firmware and BIOS, as they always seem to be shipped in IR mode. IT mode is plain SAS2 Initiator-Target mode, where the disks are just plain disks without needing to create volumes or any other nonsense. -- john r pierce 37N 122W somewhere on the middle of the left coast
