Punchline: I had a chat with one of the top techs at this
mail system provider, and told him about the OpenBSD
experience with Adaptec. He told me they have come to the
same conclusion and that their next generation product would
have a much better (by OpenBSD standards) manufacturer for
the RAID systems...
More of a punch line would be if they actually see the light for real as
well and use OpenBSD instead with softraid and all. Wouldn't that be the
killer. They already know about BSD, so using OpenBSD shouldn't really
be such a problem but going from BSD to Linux for mail system? OK, I am
not a big fan of Linux, I must confess, but using something rock solid
and on email, I know of none that come close to OpenBSD for stability ,
security and all. That would make their stuff install and forget for
ever! Call that good marketing, that's what company wants, install and
forget.
But sure good writing as usual and I hope they listen to you too Nick.
They couldn't have someone more convincing to listen too!
Thanks for all the information. You are, of cause, right about the
quality of Adaptec cards. Any suggestions for a nice and not too
expensive 32/64bit PCI hardware RAID card supporting RAID 5 and maybe
even 6?

I recently bought an LSI MegaRAID 320-1LP on eBay
for $25. The battery backup unit to make it go fast cost $45. I'm still
setting up this server (got some 15K 72G U320 on the way) but here it is with
6 32G Fujitsu drives configured as 3 RAID1 volumes. I wouldn't touch RAID5
myself, but you can set this card up that way.

It shows up as an ami, so it is fully accessible through bioctl.
$ sudo bioctl -v ami0

Thanks, Marco for writing bioctl!
