Minimal Nested vCenter 6 Lab – Configuring the vMotion Network

In this post, we will configure the vMotion networking for our ESXi hosts. Each ESXi host has 8 vmincs as show below

esxi-vmnic

As mentioned in the first post of this series, vmnic0 and vmnic1 are already used for management. vmnic2 and vmnic3 will be used for vMotion, and vmnic4 and vmnic5 will be used for iSCSI

vMotion is pretty easy to configure, we just create a VMkernel port group, specify that i will be used for vMotion traffic and assign an IP address to it.

However, the trick is on the iSCSI configuration, where two VMMkernel port need to be created on each host. Each VMkernel port will have one active vminc and another non used vmnic. This is way to have redundant paths to our iSCSI Target, and this is also the only configuration supported by VMware.

We already have one standard vSwitch named vSwitch0 used for hosts managment, and we’ll create VMKernel port group in a new vSwitch that will be used for vMotion.

Let’s go ahead and create our vMotion port group.

Configuring the vMotion Network

Go to the first host, in my lab esx1.contoso.local, then go to Manage > Networking > Virtual Switches and click on Add host networking

CreateNewNetwork

Choose VMKernel Network Adapter

vCenterLab-vMotionNetwork

We’ll create our vMotion port group in a new vSwitch

vCenterLab-vMotionNetwork

Select the appropriate vmnic that will be used for vMotion traffic (vmnic2 and vmnic3)

vCenterLab-vMotionNetwork

Confirm you selection then click on Next

vCenterLab-vMotionNetwork

Give a descriptive name to your port group, and specify that it will be used for vMotion

vCenterLab-vMotionNetwork

Assign a static IP in the vMotion range (172.16.0.0/16)

vCenterLab-vMotionNetwork

Confirm your port group creation by clicking on Finish

vCenterLab-vMotionNetwork

Our VMKernel vMotion port group is now created in a new vSwitch1

vCenterLab-vMotionNetwork

 

This was short and easy. We’ll just need to follow the same steps in our second host and we’re done with our vMotion network.

vMotion is now configured on both hosts.

In the next post, we’ll configure the iSCSI network to enable the ESXi hosts for storage connectivity
