Hi to all,
I am new to ESXi and I need some advice from the experts about networking configuration on ESXi 5 host.
Setup looks like this.
One HP DL380 G7 Server running ESXi 5, 3 Server 2K8R2 Enterprise VM's, 4 LAN ports on server, one dedicated to management network.
I would like to setup networking in the following way:
Every VM should have access to physical network but I would also like that all three VM's communicate to each other not through physical network interfaces but through intra-server networking basically not touching physical network for VM to VM networking.
If I understand networking in ESXi correctly, if I assign same vSwitch to all VM's they will talk to each other through intra server networking, but then I will be able to assign only one physical LAN card to that vSwitch if my physical switch doesn't support teaming and in that case I'm stuck to 1000 Mbps for all three VM's total throughput?
Then I was thinking about creating three vSwitches, assign one physical LAN card to each vSwitch and assign every VM to it's own vSwitch, but in that case every VM will communicate to each other through physical network right?
Next idea was to do it in the same way as previously mentioned but additionally to create one more vSwitch without any physical NIC's assigned to it, connect all three VM's to it as additional virtual LAN card on VM and have different subnet for that second network and setup all services on all VM's to communicate to each other through that (other) network. Then I would have some issues with name resolution between VM's if I don't reference VM's by IP? Or maybe not because they are all in the same broadcast domain just to put that other intra-host network adapter higher on the priority list in VM networking settings than physically bound network adapter?
Thanks for help.
