I discovered that arc(4) is support on OpenBSD/sparc64. Having never
used one of these cards, I am assuming that configuration is done in
basically the same way as most BIOS configured RAID cards. Is it
possible to configure a RAID 5 array on an i386 or amd64 box and then
move it to a sparc64 box? The Areca cards look nice and are supported
by bio(4) and bioctl(8) which is just fantastic!
