  Yes, the white PCIe slot on the riser is the integrated storage slot. The black slot is an x16 slot that is used for add-on cards.
 I have a Poweredge R410 that has a Perc 6/i installed and I am looking to install a Dell SAS 6GB External Controller so I can have an external SAS port for a tape drive.  Does the 6/i use the port I need to install this?  Or is there still a PCIx slot available?  Thank you.
