How to setup Multi-NIC vMotion on a distributed vSwitch
This article provides you an overview of the steps required to setup a Multi-NIC vMotion configuration on an existing distributed Switch with the vSphere 5.1 web client. This article is created to act as reference material for the designing your vMotion network series.
Configuring Multi-NIC vMotion is done at two layers, first the distributed switch layer where we are going to create two distributed port groups and the second layer is the host layer. At the host layer we are going to configure two VMkernel NICs and connect them to the appropriate distributed port group.
Before you start you need to have ready two ip-addresses for the VMkernel NICs, their respective subnet and their VLAN ID.
Distributed switch level
The first two steps are done at the distributed switch level, click on the networking icon in the home screen and select the distributed switch.
Step 1: Create the vMotion distributed port groups on the distributed switch
The initial configuration is pretty much basic, just provide a name and use the defaults:
4: Review the settings and click finish.
Do the same for the second distributed port group, name that vMotion-02
Step 2: Configuring the vMotion distributed port groups
Configuring the vMotion distributed port groups consist of two changes. Enter the VLAN ID and set the correct failover order.
1: Select distributed Port Group vMotion-01 in the left side of your screen and right click and select edit settings.
2: Go to VLAN, select VLAN as VLAN type and enter the first VLAN used by the first VMkernel NIC.
4: Click OK
We are done at the distributed switch level, the distributed switch now updates all connected hosts and each host has access to the distributed port groups. Two vMotion enabled VMkernel NICs are configured at host level. Go to Hosts and Clusters view.
6: Click on next and review the settings.
Create the second vMotion enabled VMkernel NIC. Configure identically except:
1: Select vMotion-02 portgroup
2: Enter IP-address corresponding with the VLAN ID on distributed Port Group vMotion-02.
The setup of a Multi-NiC vMotion configuration on a single host is complete. Repeat Step 3 on each host in the cluster.
