I'm using both regular vinum and ataraid on the production server (which runs a fairly recent -CURRENT). They both work fine, and ataraid even updates the metadata for the Highpoint RocketRAID 454 correctly (so that arrays show up in the BIOS config). > That takes us back down to geom-vinum, geom-stripe,=20 > perhaps some=20 > SCSI RAID controllers which aren't affected by any of the ATA stuff,=20 > and maybe ccd. I was under the impression CCD didn't to "normal" RAID-0, but instead = used some sort of interleaved concatenated mode that resembled RAID-0 for = some use-cases. If I'm wrong then that makes the number of choices 5 instead = of 4. :-) /Daniel Eriksson
