Expanding a vSAN Cluster

You can expand an existing vSAN cluster by adding hosts or adding devices to existing hosts, without disrupting any ongoing operations.

Use one of the following methods to expand your vSAN cluster.

• Add new ESXi hosts to the cluster that are configured using the supported cache and capacity devices. See Add a Host to the vSAN Cluster.
• Move existing ESXi hosts to the vSAN cluster and configure them by using host profile. See Configuring Hosts in the vSAN Cluster Using Host Profile.
• Add new capacity devices to ESXi hosts that are cluster members. See Add Devices to the Disk Group in vSAN Cluster.
