For all of this to work we need to get a couple of VMkernel network interfaces created per ESX host. This will give us vMotions and for VSAN connectivity. To delve more into VSAN I would highly recommend that you pick up a copy of Essential Virtual SAN by Duncan Epping and Cormac Hogan.

1. Log in using an account that has permission to configure the environment.
2. Select Home and Hosts and Clusters
3. Click on networking icon, right click  the Distributed Switch, Click Add and Manage Hosts…
4. Select Add Hosts, Select  Next.
5. Click New Hosts…
6. Select the Hosts you want to add to the Distributed Switch, Select OK,  and select Next.
7. Make sure Manage physical adapters and Manage VMkernel adapters are selected. Click Next.
8. Select the first vmnic you want to add to the dswitch and click Assign uplink.
   
9. Select Uplink 1. Click OK. Repeat for all remaining vmnics.
10.  Once you have added all your vmnic to their uplinks it should look similar to the below picture. Click Next.
11. The next following steps will be about adding in the vmkernel network adapters and will show you how to add in one adapter. You will need to go through and add two adapters to each host; 1 for vMotion and one for VSAN. Click New Adapter.
12. Click Browse.
13. We’ll be adding a vMotion port group, so select vMotion and click, OK.
14. Select Next.
15. Select vMotion Traffic. Leave the rest as defaults and click Next.
    
    
16. Select Use Static IPv4 Settings and enter in the network details. Select Next.
17. check all the details are correct and select finish.
18. Go back to step 11 and add vMotion vmknics and VSAN vmknics to all your hosts. If you’ve been following the previous posts/docs, once you’ve finished it should look like the below.
19. Select Next.
20. Check the details and Select Next.

vSphere will go off and add your hosts the the dswitch and create vmknics for VSAN and vMotion.

So where are we now? We have one more step to go before enabling VSAN.
