Dell Storage Backend

The CSI drivers by Dell implement an interface between CSI (CSI spec v1.6) enabled CO and Dell Storage Arrays. It is a plug-in that is installed in Kubernetes to provide persistent storage using the Dell storage system.

For details about Dell CSIs, see https://dell.github.io/csm-docs/docs/csidriver/.

The Dell Technologies (Dell) CSM enables simple and consistent integration, and automation experiences, extending enterprise storage capabilities to Kubernetes for cloud-native stateful applications.

Note

For every change on user-overrides to be updated on the application, you need to reapply the override before applying the Dell-storage application.

Note

csi-powerstore is enabled by default. Disable any other CSI/CSM if not used, otherwise it could cause the application to fail on apply.
