VMKernel Port versus Virtual Machine Port Group
Posted on 2012-08-20
I have ESXi v4.1 running on a small network. I have 9 virtual machines running on this host. Close to all of the throughput is being sent to and from internet hosts so bandwidth currently is not a big deal, however, I did notice copying data from VM to VM very rarely exceeds 100 mbps. I have 1 gbps NICs on the VM's and only copying within the same ESXi host. I'm beginning to wonder if it's my networking configuration. I have one vswitch and within that one vswitch I have both a virtual machine port group and a VMKernel Port. I have two NIC's in this server and each NIC has the ability to access the IP range assigned for this ESXi host. Do I need to create another virtual switch and add a virtual machine port group to it and move my VM's in there?
