    <description>&lt;P&gt;&lt;STRONG&gt;&lt;FONT color="#000000"&gt;Mike had a Virtual Connect stacking question from a customer:&lt;/FONT&gt;&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;********************&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Customer wants to stack c7000’s so that bladeA in c7000 #1 can communicate with bladeB in C7000#2 without having to go to uplink switches.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;My thinking on this is that basically they would create a vNet with no uplinks, then assign the network (vNet) to all desired blades in the server profiles -- with the stacking links providing the communication path.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;My question is…Is there an “official” doc on how to set this up?&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I checked the VC Cookbook and there is a scenario for Private Networks (Simple vNet)..but not stacked…&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Any help would be very much appreciated…&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Thanks!!&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;******************&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;STRONG&gt;&lt;FONT color="#000000"&gt;From Carl:&lt;/FONT&gt;&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;******************&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Any servers connected to the same vnet &amp;nbsp;will talk to each other without using uplinks if they are in the same stack. The vnet can have uplinks – they will not be used unless traffic needs to egress the chassis.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;******************&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;STRONG&gt;&lt;FONT color="#000000"&gt;And from Steve:&lt;/FONT&gt;&lt;/STRONG&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;*****************&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;So, if you create the vNet you mentioned….&amp;nbsp; But add a single uplink, then do the same in the other enclosure and connect them together.&amp;nbsp; This will work with a single uplink to that vNet.&amp;nbsp; Again this will work, much like using a cross connect between two servers, if you need to add a third enclosure, you will need to link through a switch.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;********************&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;STRONG&gt;&lt;FONT color="#000000"&gt;Comments?
