You'll probably want to make sure you get one of their DC-390U3* Ultra160 controllers. The DC-315/395 controllers have a Tekram Ultra SCSI chip that (apparantly) doesn't have its own SCSI phase engine and so requires multiple interrupts per transaction. They also had some older boards based on the AMD 53c974 chip, which have similar issues and will be fairly slow. (I think that was the DC-390T) If you get one of their Ultra160 boards, though (which use LSI Logic chips) you should be fine; the sym driver works well. Tekram has been very good about supporting FreeBSD -- they've even written CAM drivers for their various SCSI controllers.
