I need a little help wrapping my head around networking with vmware.
1.) Is it the case that one can NOT uplink 2 standard vswitches to the SAME pNIC (vmnic)? So, imagine vswitch0 and vswitch1 and both have uplinks to the same pair of 10G pNICs. Is that allowed?
2.) When one configures uplinks, is it vswitch-centric or port-group centric? See attached document from Scott Lowe's book. Focus on the top drawing. It looks like uplinking is a port group-centric thing, not vswitch-centric. Which is it?
I always thought that the reason why one configures more than one vswitch was so that you can separate traffic. So, imagine having vswitch0 uplinked to a pair of 1G pNICs and vswitch1 uplinked to a separate pair of 1G pNICs. That makes sense. BUT, I am trying to figure out why more than one vswitch should be configured in the same hypervisor on the same host if I only have 2 10G pNICs. What's the point, especially if I can have 1 vswitch with several port groups and uplink from a port-group perspective instead? This is what Scott Lowe is showing. He shows what looks like port group-centric uplinking, but what confuses me about what Scott Lowe shows is that he STILL has more than 1 vswitch.
I dont get it. What am I missing, besides a brain?
