Question on SC08Ge Controller 488765-B21

SC08Ge 488765-B21 is a two port x 4 lanes multiport SAS controller.  It is supposed to be backwards compatible with SATA.   We are using a generic SFF-8088 (host adapter side) to four lane breakout cable.   No matter how we try this, the controller does NOT see attached SATA devices in external bays.    Can someone suggest why this may be?    It is starting to look like the controller only works with SAS devices?

What are the recommended cables to go from this controller to an individual SATA ESATA connector?
