LSI 150-4 works like a charm (OpenBSD 3.6 + driver cleanup patches from CVS)... I have many of them. Both in 32 and 64 bit slots. Now I use it on some OpenBSD 3.7 installations as well.
What can I say... I wont buy any adaptec cards ;-)

So they work well in 32-bit PCI slots as well? I thought (for no other than visual reasons) that they required a 64-bit slot. We were thinking about byuing one for our ISP1100 (somewhat old, but stable), which has no 64-bit PCI slot. Do you know if there is anything special to think about or will it work with just about any 32-bit PCI slot?
Can anyone else comment (pros/cons) on the ISP1100 and the LSI MegaRAID 150-4?
** Rogier Krieger replied: LSI Logic mentions on its website (that is, its knowledge base; I don't have a direct link) that these cards also work in 32 bit slots. It does so for me, without a glitch. I think I also mentioned this in my first post. I'll try a 64 bit slot (for performance comparison) once the appropriate hardware arrives.

I've rarely had problems using a 64-bit card in a 32-bit slot, as long as the card would physically fit without shorting the exposed card edge. The one time I did have a problem, I think it was a problem between the card, the motherboard and OpenBSD; the card worked fine in another 32-bit PCI system under some kind of Linux, as well as Windows.
** Per-Olov Sjvholm replied: I think you must have the following to put the 150-4 card in a 32 bit slot: * The motherboard must support PCI 1.1 (it probably does if it's not to old). * You also have to have a notch at the rear end of the pci slot. If you do not have it you can't put the card in the slot (I think all motherboards not older than a couple of years have this).

Thanks a lot for the pleasant replies! I'm very excited about getting some real RAID into the box. Now I only hope it's within our limited budget (including new disks and all). I'm trying to convince myself that software RAID isn't worth the hassle (root-on-raid issues, non-GENERIC etc).
Sincerely, Alexande
