Native support, at least as far as I'm concerned, hinges on integration of devfs as the default device access mechanism. 2) There is a Compaq SCSI comtroller that has transparent RAID. There is a driver for FreeBSD, although it hasn't been integrated. Look at the -hackers list archive, subject "Re: RAID" for details on the Compaq controller. Software RAID is pretty much unusable because of [lack of] speed, although there was talk at one time of altering the AIC-7770 based controller's sequencer code (since it is home brew anyway) to support RAID at that level, which would make it more realistic.
