Sorry you will need two controllers.  SAS is to parallel SCSI as SATA 
is to parallel ATA.
So far I do not know of a controller that supports both on the same 
adapter.  If your system
already has one flavor, you only need a controller for the other.

As for the 80-pin SCA backplane, most will support Ultra 160, but 
Ultra320 requires fairly
tight impedance control for solid operation.
