PowerMax CSI Driver scenario query regarding Isolation Mechanism

Current example setup details as follows.

Unisphere Endpoint: 
    • For Site-1 - Dev/ Test/ PROD Unisphere Endpoint = https://xx.xx.xx.xx:8443
    • For Site-2 - Dev/ Test/ PROD Unisphere Endpoint = https://xx.xx.xx.xx:8443
    • A single Unisphere endpoint is used for Dev, Test, and Prod on each sites above.

User Account Scope:
    • A single Unisphere user account (test-admin) with full admin PowerMax array access is used.
    • This account has visibility and control across Dev, Test, and Prod storage.
    • There are no dedicated Unisphere users per environment.

CSI Driver Deployment:
    • Each environment (Dev, Test, Prod) runs on its own Kubernetes cluster.
        o Dev → Dev_Cluster
        o Test → Test_Cluster
        o Prod → Prod_Cluster
• Each cluster would have its own CSI driver deployment, which is good practice.

Are my key observations on isolation of the CSI driver capability among the environments correct?
