I have two different models of the DPT SmartRAID board -- both are buggy
and cause data loss (software raid corruption) on high disk loads such as
copying large files. I'm still using them for $$ reasons, and on
relatively low loads they seem to be OK. There are some notes floating
around the net that some of these boards have bugs in the microcode. I've
confirmed that for one type of board I have. Sorry, don't know the model
numbers offhand, they are buttoned up in the machines. I have a spare
daughterboard that is a 4050.
If I had the option, I would make boat anchors of the cards and the scsii
disks that go with them. They've been nothing but trouble. We have a
dozen Linux raid 1 and 5 hosts and these are the only ones that ever
fault. We run very low duty cycle on the disk IO so it's not a problem
for us at the moment.
