 * Does FreeBSD-2.1.0 support any SCSI controllers capable of of RAID
 * mirroring support?

No, but there is a software striping/mirroring device driver called
"ccd" in -current and -stable.  You can use an ordinary SCSI
controller to manage a mirrored volume! :)

See

  http://stampede.cs.berkeley.edu/ccd/

for details.
