Anything supported by mpi(4) mfi(4) or mpii(4) should be ok (covering all the hardware raid options on dell boxes should work). Out of these mpi and mfi are more widely used, so will have had more testing. For older hardware ami(4) is ok too but it sounds like you're looking for something new. > I've actually spent a bit more time and gotten software RAID working > and will send some updates to the authors of the very helpful software > RAID guidelines that I found. The only _maintained_ software raid on OpenBSD is softraid(4), that has only just recently had code written to allow booting from it and it's not committed yet. For what you're talking about using the machine for, I'd be much happier with a single disk than an unmaintained software raid setup. And if there's a choice between two (carp'd?) boxes with single disks, or one box with raid, two boxes would be hugely preferable.
