Explanation
You can add ESXi hosts to a running vSAN cluster without disrupting any ongoing operations. The new host's resources become associated with the cluster. Verify that the resources, including drivers, firmware, and storage I/O controllers, are listed in the VMware recommends creating uniformly configured hosts in the vSAN cluster, so you have an even distribution of components and objects across devices in the cluster. However, there might be situations where the cluster becomes unevenly balanced, particularly during maintenance or if you overcommit the capacity of the vSAN datastore with excessive virtual machine deployments. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan.doc/GUID- EA47DC82-4678-4430-AEF7-1D77FB9C77DB.html
