</div>
<div>
<p class="MsoNormal">In the setup that I am designing, I just need 1 more additional port on the switches.<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">So I was wondering whether the following design would work.<o:p></o:p></p>
<div>
<p class="MsoNormal"><b>HCA1 and 2 are bonded</b> on both nodes<br>

<p class="MsoNormal"><b>Host 1 Host 2</b>

</div>
<p class="MsoNormal">| HCA 1 |------------------->| Switch A |<span style="color:red">------- x -------></span>| HCA 1 |<o:p></o:p></p>
<div>
<p class="MsoNormal">------------- ---------------- -------------<br>
------------- ---------------- -------------<br>
| HCA 2 |------------------->| Switch B |------------------->| HCA 2 |<br>
------------- ---------------- -------------<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><b>Host 1 Host 2</b>
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Sender Receiver<o:p></o:p></p>

<b>HCA1 and 2 are bonded</b> on both nodes<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><b>Switch A and B are not connected.</b><o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Say, Host1-HCA1 is sending data to Host2-HCA1, when there is a link failure between Switch A and Host2-HCA1. Will the configuration automatically detect this and continue sending the data through Host1-HCA2
to Host2-HCA2 through Switch B?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Also, since the both the switches are bonded, and the subnet manager is running on any one host,will this be considered a single fabric?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Any insights would be helpful.<o:p></o:p></p>
