During a vSAN design workshop, the customer expressed the following requirements: The ESXi hosts will have their disk related hardware changed to become vSAN nodes. The default storage policy will be based on an FTT=2 (Failures to Tolerate). The vSAN Primary level of failures to tolerate (PFTT) will be set to a value of 2. Based on the request, the architect was shown the following information about the current cluster: The number of existing ESXi hosts is 8. vSphere High Availability (HA) Admission control set to 37.5%. How does this information impact the vSAN cluster design?
