It's a little unclear what help you are asking for here.
In terms of "freeing up resources" can you elaborate on what you are referring too?
In regards to your query about what version of SolidFire Element is required by best practices? Do you mean in terms of Openshift deployments? I believe Redhat Openshift will have some documentation about what versions of NetApp software is supported, so that might be a good place to start.
