Storage DRS and initial placement

Hi community! 

If I turn on the Fully Automated setting on a Datastore Cluster using SDRS-

Will SDRS always run?  I don't want it to run the moment I turn it on and I have no SDRS Scheduling configured on the "SDRS Scheduling" tab of the Datastore cluster.

All I want initially is initial placement or "load balancing" of VMs across datastores in the datastore cluster as I move VMs to it.

Any wisdom/guidance really appreciated.

Off to study up on SDRS some more!

SDRS will always run. But it will trigger normally on scenarios when there is a load on specific datastore or if there is a space crunch on specific datastore and the VM performance is impacted.

Yes, that is correct. SDRS will always run but it would be triggered if space or IO threshold is crossed. Initial placement would be done as and when new VM is getting created or other VM is sVmotion to datastore cluster.

If it is useful, plz mark answer as correct or helpful. ---------------------------------------------------------------- Thanks & Regards Vikas, VCP50, MCTS on AD, SCJP6.0. http://vThinkBeyondVM.com ----------------------------------------------------------------- Disclaimer: Any views or opinions expressed here are strictly my own.

Any idea if we need only VM INITIAL PLACMENTS

What is the parameter to use in advanced settings?

Fully automated - will that seek/ask user approval for initial placement?

Sateesh_vCloud​ can you clarify your question? Only need initial placement...for what? Parameter to use in advanced settings, for what?

When you have DRS level 1 enabled, only initial placements are covered and it'll prompt. For other levels, it becomes more automated where it will not prompt for initial placement decisions.
