Re: SVM Trident limits/config

Can you not use the Kubernetes  Resource  Quoting objects  to control the
same  ( Limits applied at the openshift/k8 cluster side  ) ?

https://kubernetes.io/docs/concepts/policy/resource-quotas/

You would need to have a mechanism to  control these  resource quota
numbers across  multiple namespaces/ in a given cluster
to make sure you did not exceed what was available to provision in the
associated  trident backend aggregate for the SVM you were pointing at .

This seemed like an approach to me anyway .  Is the above not feasible ?
