Re: RAID and OpenBSD

[Chuck Yerkes <chuck@snew.com>]

My girlfriend is fighting some PCI based RAID card at work.  And the
machine is giving her trouble.  We're both MORE advocates of a box
that you attach to via SCSI.  Host sees SCSI, box does the RAID work
(hopefully with decent RAM cache and perhaps a battery backed write
cache.

Advantages include that when the machine smokes, you pull
that scsi cable out and attach it to something else.  Oh,
and they tend to be OS independant - I've attached high
end RAID to my Apple Laptop in MacOS to back it up before
installing OS X (roaring at 5-10 MB/s :).  The machine
sees a couple 100GB disks.

That said, SCSI RAID cards are out there and fast and 
work pretty well.  Software RAID can work if the machine
isn't CPU bound and has really good I/O.
