After you have set up your vSAN cluster, you can add hosts and capacity devices, remove hosts and devices, and manage failure scenarios. Expanding a vSAN ClusterYou can expand an existing vSAN cluster by adding hosts or adding devices to existing hosts, without disrupting any ongoing operations. Sharing Remote Datastores with HCI MeshvSAN clusters can share their datastores with other vSAN clusters. You can provision VMs running on the local cluster use storage space on the remote datastore. Working with Maintenance ModeBefore you shut down, reboot, or disconnect a host that is a member of a vSAN cluster, you must put the host in maintenance mode. Managing Fault Domains in vSAN ClustersFault domains enable you to protect against rack or chassis failure if your vSAN cluster spans across multiple racks or blade server chassis. You can create fault domains and add one or more hosts to each fault domain. Using the vSAN iSCSI Target ServiceUse the iSCSI target service to enable hosts and physical workloads that reside outside the vSAN cluster to access the vSAN datastore. vSAN File ServiceUse the vSAN file service to create file shares in the vSAN datastore that client workstations or VMs can access. The data stored in a file share can be accessed from any device that has access rights. Migrate a Hybrid vSAN Cluster to an All-Flash ClusterYou can migrate the disk groups in a hybrid vSAN cluster to all-flash disk groups. Shutting Down and Restarting the vSAN ClusterWhen necessary, you can shut down the entire vSAN cluster.
