Note: To connect to a PowerFlex 4.5 array, the SDC image will need to be changed to dellemc/sdc:4.5.
- If using helm to install, you will need to make this change in your values.yaml file. See helm install documentation for details.
- If using CSM-Operator to install, you will need to make this change in your samples file. See operator install documentation for details.
