I get most of the concept of a dvSwitch, but how do I actually assign a portgroup to a specific uplink? Right now, I seem to create port groups and they connect to all the uplinks. I guess this will not work as some pNICs won't connect the VMs (portgroups) to the correct physical network.
I can only have a single "uplink collection" per dvSwitch, right? So there must be something I'm not getting here...
As I understand it, portgroups were, in the old switchtype, separated to different vSwitches to find the correct pNics and vlans, how is this separation done now that all portgroups connect to the same dvswitch?

Hi Henrik,
I am not sure I understand exactly what you are asking but I will give it a go.
The seperation you are talking about works exactly the same with vNetwork Distributed Switches as it did with vNetwork Standard Switches. Just as you could have multiple vNSSs each with it's own uplink you can also have muliple vNDSs each with it's own uplink. From this point of view nothing has changed - if you had 3 vNSSs to achieve your networking environment before you would still have 3 vNDSs to achieve the same thing now. The only thing that has really changed is that the vNDS is created in vCenter and can be assigned to mutiple hosts (create once and reuse) whereas the vNSSs had to be created on each host individually.
You can have multiple portgroups per vNDS (separated with VLAN tagging) and this behaviour is also unchanged from how it is with vNSSs (you can have one or more portgroups defined on a vNSS too).

Argh.. Of course you are right. My bad. One simply, like with an old vswitch, configure the properties for the port group to enable or disable the possibility for that portgroup to use the uplink. Just like with a NIC in an old switch.
Thanks for getting me on track..

Still, in many VMWare presentations regarding dvSwitch they merge previously separate vSwitches into a single dvSwitch.
Any idea why?

Hi Henrik,
I have no idea. I cannot think of anything "new" with a vNetwork Distributed Switch that would mean you'd have any less of them than you had vNetwork Standard Switches.
I could be wrong!
Cheers,
