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

SDC | iscsi-initiator-utils multipathd nfs-utils |
nfs-utils | iscsi-initiator-utils multipathd nvme-cli nfs-utils |
Notes:
- The required OS dependencies are only for the protocol needed (e.g. if NVMe isn’t the storage access protocol then nvme-cli is not required).
- The host operating system/version being used must align with what each Dell Storage platform supports. Please visit E-Lab Navigator for specific Dell Storage platform host operating system level support matrices.
