Both disk striping and drive concatentation are possible, though
you must install the patches yourself.
The CCD driver is usable from the NetBSD i386 sources to
concatenate disks (disk concatenation is not a very general
soloution).
There is disk striping code, originally from MIT, which Rod Grimes
has had working under FreeBSD for quite some time.
There is ongoing work on logical device addressing as a general
soloution.
There is experimental work in terms of specific controller
sequencer code rewrites for (potentially) full RAID support.
The Compaq RAID SCSI controller is a full on RAID implementation,
and is probably the best soloution. A driver for this controller
is available (see the -hackers list archives on www.freebsg.org).
