Pass the VMware VCAP-Storage 3V0-23.25 Questions and answers with CertsForce

Cross-cluster capacity sharing, also known as vSAN datastore sharing or HCI Mesh, allows vSAN HCI clusters or vSAN storage clusters to share remote datastores with other vSAN HCI clusters or vSAN compute clusters. A required availability setting is to configure vSphere HA failure response for “Datastore with APD” on the client cluster to “Power off and restart VMs.” This ensures that if a remote vSAN datastore becomes unavailable to a host, vSphere HA can respond appropriately and restart affected virtual machines on hosts that can access the datastore. The latency option is incorrect because vSAN storage cluster guidance requires latency below five milliseconds between client and server ESX hosts, not a minimum of ten milliseconds. The VM object placement option is also incorrect because all objects that make up a VM must reside on the same datastore, not multiple datastores. Finally, client and server clusters must use compatible vSAN architectures; vSAN OSA and vSAN ESA cannot share datastores with each other.

Disabling the vSAN iSCSI Target Service stops the service that presents iSCSI targets and LUNs to initiators, but it does not automatically delete the targets or LUNs. The vSAN administration guidance states that if an administrator wants to remove vSAN iSCSI objects and reclaim capacity, the LUNs and targets must be deleted manually before or after disabling the service. Therefore, when the service is disabled, the existing targets and LUNs remain in the vSAN datastore but are no longer accessible to the clustered legacy application. This behavior prevents accidental deletion of application or quorum data simply because the service is turned off. The targets are not archived for a fixed retention period, and they are not automatically migrated to another namespace for retention. They are also not deleted automatically. Operationally, administrators should confirm that the legacy application no longer depends on the LUNs before disabling the service or should remove the iSCSI objects through the supported workflow when decommissioning is complete.
