Greetings,<br><br>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.<br>
<br>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?<br><br>Thanks,<br><br>Jeff<br clear="all"><br>-- <br>Jeff Cleverley<br>Unix Systems Administrator<br>
