The Capacity Reserve feature in vSAN 8.0 OSA reduces the amount of capacity reserved for transient and rebuild operations by using a slack space threshold. This threshold is calculated based on the size of the largest component in the cluster and the number of failures to tolerate. If the used space on vSAN datastore exceeds the suggested slack space threshold, the feature will not operate properly and vSAN will revert to using the host rebuild reserve threshold. The other scenarios will not affect the Capacity Reserve feature. References: [VMware vSAN Specialist v2 EXAM 5V0-22.23], page 28

To prevent vCenter notifications of vSAN Health status during a scheduled maintenance window, the administrator can disable the alarm from the HTML client. This will suppress the alerts for a specified duration or until the alarm is re-enabled. Disabling the performance service, running performance diagnostics, or disabling SNMP service will not affect the vSAN Health status notifications.

The minimum required number of hosts to provide data redundancy for a vSAN stretched cluster using dual-site mirroring and local protection with 1 failure - RAID-1 (Mirroring) is six hosts. This is because a vSAN stretched cluster requires at least three hosts per site, and each site must have enough hosts to tolerate one host failure. Therefore, the minimum configuration is three hosts per site, plus one witness host at a third site, for a total of six hosts. References: [VMware vSAN Specialist v2 EXAM 5V0-22.23], page 14
