Jason Thorpe beépített egy kísérleti ATA raid támogatást a NetBSD kernelébe. Egyelőre nem a komolyabb vezérlőkhöz (mint az Adaptec vagy a 3Ware), hanem csak az egyszerűbbekhez, ebben az esetben a Promise vezérlőkhöz.

Folks...
I just checked in some experimental support for RAID volumes found
on ATA "RAID" controllers; not the smart controllers (like e.g. Adaptec
and 3Ware), but the dumb ones ... in this particular case, Promise.
These controllers are just IDE controllers with a BIOS that can configure
RAID volumes, write config blocks to the disks, and do I/O to the volumes,
for the purpose of booting. The OS has to implement the RAID in software,
using the configuration data that is written to the disks by the BIOS.
The functionality is pretty basic at this point, but it works well
enough for me to use the RAID0 volume on this new Intel server I have
(which has a Win2k Advanced Server installation that I need to preserve).
Attached are boot messages from my machine (a dual 2.4GHz Xeon w/ HT,
though I am only using a uniprocessor kernel on it at the moment); it
is using an NFS root right now, since I was using PXE to load kernels
while working on the ATA RAID code.
Enjoy!
