I agree with D answer: Each host in a vSAN cluster is an implicit fault domain. vSAN automatically distributes components of a vSAN object across fault domains in a cluster based on the Number of Failures to Tolerate rule in the assigned storage policy. To mitigate this risk, place the servers in a vSAN cluster across server racks and configure a fault domain for each rack in the vSAN UI. This instructs vSAN to distribute components across server racks to eliminate the risk of a rack failure taking multiple objects offline. This feature is commonly referred to as "Rack Awareness". https://storagehub.vmware.com/t/vsan-6-7-update-1-technical-overview/fault-domains-31/
