Give the man a kewpie doll!!! I'm dealing with modest server hardware, which didn't have workable hardware RAID. I've found the hardware RAID compatibility chart to be awkward: much of the recommended hardware is no longer manufactured or not sufficiently specified to rely on. Naming a chipset is not enough: a model number is really ideal, because saying "LSI" or "Dell Perc" covers dozens of different cards, some of which may be very reliable but others are not. I used to recommend 3Ware from good experience and and general UNIX/Linux compatibillity, but they got bought by LSI: gods only know what their quality is these days. Also, I just went and tried the sensible guidelines at http://jpiasetz.tumblr.com/post/483365684/software-raid-on-openbsd-using-softraid, which use softraid for non-/boot partitions. Seems reasonable, but this command simply fails: # bioctl -C force -c 1 -l /dev/wd0d,/dev/wd1d softraid0 # dd if=/dev/zero of=/dev/rsd0c bs=1m count=1 bioctl: Can't locate raid0 device via /dev/bio The documentation on bioctl is reasonably, and detailed, and not very useful due to not having examples for noobs.
