Hello simpleguy3k, So that card is a combo card in that if you have hard drives connected to it you can use it as a raid card, or if no drives are direct connected to the card then it can be used as a SAS passthrough card. Also I checked the Compatibility guide & it does support a couple of different tape units as well. [URL]  Please let us know if you have any other questions.
