If I am not wrong Manual Storage Vmotion is moving VM from one datastore to another.
I wonder if there is automatic  Storage Vmotion, if there is , then in which scenario that the automatic SVmotion happens?

Thank you

Correct.

I wonder if there is automatic  Storage Vmotion, if there is , then in which scenario that the automatic SVmotion happens?

Yes, the function is called Storage DRS (SDRS), the similar to DRS which moves VMs between hosts in a Host Cluster, but Storage DRS automatically moves VM (disks/storage) between datastores, in a Datastore Cluster.

and this is based on many metrics, latency, datastore space, and can be set to manual or automatic.

You can read more about Storage DRS here

Moving a VM is an informed decision.

If you need some automation added into it, then you have to consider DRS (Dynamic Resourse Scheduler) -

More info on DRS is here -

https://pubs.vmware.com/vsphere-50/index.jsp?topic=%2Fcom.vmware.wssdk.pg.doc_50%2FPG_Ch13_Resources.15.6.html

With DRS you can introduce Automation to this process.

Hope this helps.

@Raghavendra Manavi The link and post you have posted is about DRS, we are discussing SDRS!

- Storage DRS - not DRS, there is a big difference. Moving VM Storage between Datastores , not the VM between hosts(DRS).
