c7000 stacking question...
Mike had a Virtual Connect stacking question from a customer:
********************
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.
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.
My question is…Is there an “official” doc on how to set this up?
I checked the VC Cookbook and there is a scenario for Private Networks (Simple vNet)..but not stacked…
Any help would be very much appreciated…
Thanks!!
******************
From Carl:
******************
Any servers connected to the same vnet 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.
******************
And from Steve:
*****************
So, if you create the vNet you mentioned…. But add a single uplink, then do the same in the other enclosure and connect them together. This will work with a single uplink to that vNet. 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.

Comments? Here is a link to the Multi-Enclosure Stacking document for help:
