SAS port speeds

Greetings,

We have a stack of DS4243 shelves for a NearStore running SATA/BSAS drives. We will be getting some DS4246 with the 4TB FSAS drives. I know it is supported to put them in the same stack, my understanding is everything in the stack will drop to 3 GB/s speed.

Since the HBAs run 2 ports on one chip, does that one chip control the speed for both ports A/B, or are they separate?

Thanks,

Jeff
