Hello
I would like to know if we can add an external datastore to a vSAN?
is there any KB for the same?
, Yes, you can add any external storage that is supported for ESXi to a vSAN node e.g. VMFS/NFS LUNs.
After all, these are just ESXi hosts just they also are using vSAN.
Just to be clear, you can add datastores to the hosts in a cluster, you can NOT have those datastores contribute to the vSAN datastore! Seen some people trying this in the past. vSAN Datastores only use host local capacity of direct attached disks. (SAS, SATA, NVMe)
Hi!
You can add any type of datastore (VMFS, NFS, vVOLs) to a host that participates in a vSAN Cluster, but apart from the vSAN Datastore.
However, you cannot extend the actual vSAN Datastore with other datastores (VMFS, vSAN, NFS, vVOLs), but you can add capacity disks (SATA, NVMe, SAS) that are direct attached to the host to contribute to a diskgroup.
Here are some KBs for that:
- Creating a VMFS Datastore: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-5AC611E0-7CEB-4604-A03C-F600B1BA2D23.html

I hope that this helped you with your doubt.
Good luck!
Thank you
