SATA/SAS Hardware RAID

I know it specifically says in the manual that SATA, SCSI and RAID are all not supported but it would be great to have support for at least one of the major vendors cards. Specifically I would like support for the LSI SAS 1064 hardware RAID controller (but that’s just the hardware in the box I’m looking to deploy on - the Sun x4100 - It’s not essential as I can use the IDE drive in the box but it would be nice to be able to use the hardware RAID 1 for disk redundancy). The Linux drivers for the LSI MPT Fusion controllers are open source, I don’t know about drivers for other vendors cards but I seem to remebmer OpenBSD support only LSI as they are the only ones that would give them specs for the cards. I think Highpoint and Arcea are also open source but I can’t remember off the top of my head
