strategy for choosing between two clusters

Jump to solution

Hi, 
I was wondering, when two clusters matche with our tags when allocating, what is the strategy used for choosing a cluster more than another ? Is it the amount of free storage, RAM, CPU, other ? 

On the picture , imagine my tags would have matched 2 clusters.

When multiple compute options comply with the designated constraints, vRA will use the Placement Policies configured in Cloud Assembly - at the Project level (Administration > Projects > [Project_Name] > Provisioning >Placement Policy) to select the Zone, and at the Zone level (Configure >Cloud Zones > [Cloud_Zone_Name] > Summary >Placement Policy) to select the compute.

There are only two placement strategies available at the Project level, where you're defining the logic used for selecting amongst available Cloud Zones. So I think what you're seeing is correct:

There are three placement policies you can apply at the Cloud Zone level:

I want to say I remember reading about the Advanced policy option once upon a time but I don't recall seeing it in any of my vRA environments.
