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.
