Yes -- I'm sure others will fill you in on the capabilities of
FreeBSD's DPT driver.

You can do RAID in software with the ccd (concatenated disk) driver.
There are FreeBSD and NetBSD servers running this all over the place.
It's rock solid extremely fast.
Of course, a DPT controller with cache RAM on it will be faster,
mainly because of the extra cache. But spreading a bunch of SCSI
drives over two or three NCR 8xx-based SCSI cards can be considerably
less expensive, and still extremely fast.
