A full evacuation is not mandatory. In 2-node configuration, each component has 3 objects:
– the initial data
– the replicated data
– a witness

The witness is managed by the Witness ESXi appliance. Initial data is on one node while the replicated data is in the other.

While two of these objects is online, the component is reachable. So you can stop a node or stop a witness and your VM keep running.

In full evacuation, you migrate everything from one node to the other. This option is useful when you plan to replace the host permanently. For ESXi update, select Ensure data accessibility from other hosts.

Just a couple of questions:
– On our 2 node vsan cluster, if I take 1 host out and select “Full Evacuation” maintenance mode. It errors out and does not allow you to evacuate all data.
– If above fails, how would one upgrade the ESXi host to the next version in the future (assuming a full install instead)?

Thanks…

I suggest you the following topic: https://www.yellow-bricks.com/2017/11/22/isolation-address-2-node-direct-connect-vsan-environment/

Have a good day 🙂

On your final configuration, VMware recommends that because you disable HA Heartbeat datastore that you should add additional vSAN isolation addresses from the vSAN network.
However, with a 2 node direct-connect you do not have any additional vSAN IP addresses available. What would be your recommendation on this?

Will it work with vSphere essentials plus along with a ROBO license?

No I use a JBOD HBA for vSAN. I leave vSAN manage the resiliency.
