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.
