Drivers for just the ATA/SATA channel support?
Or the FRAID disk organization?

I've seen people think the ATA/SATA driver is the FRAID
support, when the FRAID is in addition to the ATA/SATA
channel support.

In kernel 2.6, the LVM2-DM (Device Mapper) can do a lot.
It can read the FRAID vendors disk organization, and LVM2-MD
can handle provide the software RAID logic (without the
vendor's proprietary, 3rd party code)

It's also _very_broken_ too.

Furthermore, vendors change disk organization/logic
continuously between models.

Lastly, I've also not seen FRAID-5 supported yet either.
