Media 100 (Boris FX) should have compatibility and configuration info for SCSI cards (I know they used to). However, in all likelihood the card of choice is the ATTO UL4D (PCI- X version). You need to follow Media 100's recommendation for which slot to put the cards in as this is very important for performance reasons (generally you want the SCSI on a different bus than the Media 100 (or any video capture card. Probably in Slot 4). Properly installing the ATTO cards drivers and Firmware is also critical (follow ATTO's directions carefully). Other than that, you shouldn't have to make any changes to the system or FCP settings (aren't you using Media 100?). Checking with the Viper RAID manufacturer wouldn't hurt either. Often you can find the info you need online at the manufacturers websites.
