When building vCenter which Port Group do I join it to

Hiya,

We are going to build our vCenter on a Windows server which will be one of the VMs in the Cluster.

We have isolated networks for management and VM traffic both being on different VLANs and Port Groups.

Do I configure the vCenter to have one NIC and attach it to the VM port group or do I attach it to the Port Group with the management VLAN, only it will have to communicate with DNS and AD etc.

or do I create 2 vNics  on the VM and attach it to both Port Groups

Whats best practice.

A copy of our network is below:

cheers Mike
