Jordan,<br><br>It looks like the port speeds are independent.  I plugged some in on a 3270 and the A ports speeds were 3G (ds4243) and the B ports were showing 6G (ds4246).<br><br>Thanks,<br><br>Jeff<br><br><div class="gmail_quote">

<p class="MsoNormal">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>
