this is a question from a customer
"Assuming that the "Ensure Availibility" option is left as default to let the esxi nodes enter maintenance mode, what are the potential consequences in a cluster with FTT = 1? Would it be necessary to evacuate the data from the node that is entering maintenance to the other vSAN nodes? What happens when there are no more nodes to migrate to? Should we also take into account the migration timing of vSAN data to evaluate the minimum on-battery runtime required?"
