Explanation

In vSAN 8 and later, Capacity Reserve is divided into two configurable components: - Host Rebuild Reserve: ensures enough capacity is available to rebuild data after a host failure. - Operations Reserve: provides space for internal cluster operations such as object management, resynchronization, and policy changes. By adjusting these two settings, the administrator can fine-tune how much of the available underutilized capacity (~140 TB) is allocated for internal operations and fault recovery while maintaining optimal efficiency and availability.
