The correct mapping comes from the VCF 9.0 Principal and Supplemental Storage model. vSAN ESA is supported as principal storage for the Management Domain default cluster, Management Domain additional clusters, and VI Workload Domains. A vSAN Storage Cluster is not supported for the Management Domain default cluster because the initial management cluster requires a standard principal storage model, but it is supported as principal storage for Management Domain additional clusters and VI Workload Domains. Fibre Channel is supported as both principal and supplemental storage across all three domain or cluster categories, allowing either initial cluster creation or later datastore expansion. NFS v4.1 is supplemental-only across these categories. NFS can be principal only when using NFS v3; NFS v4.1 is used as supplemental storage after the domain or cluster exists. These statuses align with VCF’s distinction between principal storage, which is used during workload domain or cluster creation, and supplemental storage, which is added after creation for workloads or data-at-rest use cases.

The required action is to deploy the VMware Live Recovery appliance. In VMware Cloud Foundation 9.0, vSAN Data Protection is powered by VMware Live Recovery and provides local virtual machine protection and remote virtual machine replication for supported vSAN ESA environments. The vSAN Services configuration workflow explicitly states that before vSAN Data Protection can be used, the VMware Live Recovery appliance must be deployed. This appliance provides the data protection control plane required for protection groups, native snapshots, recovery workflows, and replication-based protection. Enabling vSAN advanced options is not sufficient because those settings control cluster behaviors such as repair timers, read locality, thin swap, unmap, and rebalance. Data Services Manager is used for database/data-service lifecycle use cases, not vSAN VM data protection. vSphere Replication can be part of broader site-recovery scenarios, but it is not the required action to enable vSAN Data Protection from the vSAN services workflow. Reference topics: vSAN Data Protection, VMware Live Recovery Appliance, vSAN Services Configuration, Local VM Protection and Replication.

In vSAN ESA, the observed three disk stripes are expected behavior for objects using RAID-1, even when the storage policy shows “Number of disk stripes per object = 1.” The vSAN policy rule defines the minimum number of capacity devices across which each replica of an object is striped, and the default value is 1. However, VMware documentation explicitly notes that objects in a vSAN ESA cluster with RAID-0 or RAID-1 configuration have 3 disk stripes, even if the default storage policy defines only 1 disk stripe. Therefore, the three stripes are not caused by site mirroring itself, nor by the VM having three objects. Site mirroring controls placement across the preferred and secondary sites in a stretched cluster, while Failures to tolerate with RAID-1 controls local host/device protection. The behavior is also not evidence that a VM-level policy override exists. The datastore-level policy can still be applied correctly; ESA’s internal RAID-1 object layout uses three stripes as part of its optimized storage architecture.
