I never heard about any LSI card called RAID which are not hardware RAID.

the base LSI SAS HBA cards, like the 2008 chip (9211-8i etc boards) have microcoded hardware raid without any write buffer or battery backup.... 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.
