The Repair Delay Timer expires, and vSAN starts automatic repair evaluation.

Once data resync completes, objects are marked as Compliant again.

vSAN verifies policy requirements and rebuilds missing components on available capacity devices.

When a host goes offline unexpectedly, vSAN treats the missing components as absent and waits for the configured repair delay timer before initiating rebuild operations. This prevents unnecessary resynchronization when a host or device returns quickly. In this scenario, the host is offline for more than an hour, so the repair delay timer expires and vSAN begins automatic repair evaluation. vSAN then checks the assigned storage policies, available capacity, and fault-domain placement requirements to determine whether missing components can be rebuilt safely on available capacity devices. If sufficient capacity and fault domains exist, vSAN creates replacement components and starts resynchronization. When the resync process finishes and the affected objects again satisfy their assigned policies, the objects are marked Compliant. The administrator does not need to manually run a resync task from vCenter, and the host does not need to be placed into maintenance mode for automatic repair. A full cluster rebalance is a separate capacity-balancing operation and is not required before object repair.

The architect should highlight that quotas and Access Based Enumeration are configured when creating the vSAN file share, with ABE available for SMB shares. In the vSAN File Service create-share workflow, the General page allows the administrator to choose the protocol and configure protocol-specific options. When SMB is selected, the share can be configured with Access Based Enumeration, which displays only files and folders that the user has permission to access and hides files or folders where the user lacks Read or equivalent permissions. The same create-share workflow also includes Storage space quotas, including a share warning threshold and a share hard quota. Therefore, the design implication is operational: quotas and ABE must be planned and applied at the file-share configuration level for SMB shares that require both controls. Quotas are not limited only to NFS shares, and ABE is not a cluster-level setting. Separate file service servers are also unnecessary because vSAN File Service supports SMB and NFS shares through the same file service architecture.

vSAN File Share SMB services are required because the storage must be consumed by Windows workstations and the application requires native NTFS permissions. SMB is the Windows-native file sharing protocol and integrates with Active Directory authentication. vSAN File Service supports SMB file shares, and Windows clients joined to the Active Directory domain configured with vSAN File Service can access those shares by using the SMB path. vSAN File Service also supports Microsoft Management Console for SMB shares, including Access Control List management, open file viewing, active sessions, and client connection management. These capabilities align directly with NTFS-style permission expectations for Windows-based graphic design workstations. vSAN File Service also supports two-node vSAN configurations, which matches the remote-site rack-space constraint of two hosts with a witness deployed remotely or in a shared location. NFSv3 does not provide native NTFS permissions for Windows clients. vSAN Storage Cluster and vSAN HCI Mesh address remote datastore capacity sharing, not SMB file access for Windows users.

Windows Server Failover Cluster shared disks require coordinated access to shared block storage. vSAN supports Windows Server Failover Clusters by providing SCSI-3 Persistent Reservation support at the virtual disk level, which allows cluster nodes to arbitrate access to a shared disk resource. One supported approach is to use the vSAN iSCSI Target Service, which presents vSAN-backed LUNs to initiators and can be used for clustered workloads that require shared block access. Another supported approach is to configure a shared virtual disk using a VMware Paravirtual SCSI controller with physical bus sharing. Physical bus sharing allows multiple VMs to access the same shared virtual disk in a WSFC configuration where supported. Raw Device Mapping is not the vSAN ESA-native solution for this requirement. NFS v4.1 is a file datastore protocol, not a WSFC shared block disk mechanism. “LSI SCSI controller per disk” does not satisfy the required shared-disk bus sharing configuration.
