Support Matrix
Supported Storage Platforms
| Platform | Version | OS Dependencies |
|---|---|---|
| PowerMax | PowerMax 2500/8500 PowerMaxOS 10 (6079) PowerMaxOS 10.0.1 (6079) PowerMaxOS 10.1 (6079) PowerMaxOS 10.2 (6079) PowerMax 2000/8000 - 5978.711.711, 5978.714.714 5978.479.479 Unisphere 10.0,10.0.1,10.1,10.2 |

| PowerFlex | 3.6.x, 4.5.x, 4.6.x | SDC |
| Unity XT | 5.2.x, 5.3.x, 5.4.x | iscsi-initiator-utils multipathd nfs-utils |
| PowerScale | OneFS 9.4, 9.5.0.x (x >= 5), 9.7, 9.8, 9.9, 9.10 | nfs-utils |
| PowerStore | 3.5, 3.6, 4.0, 4.1 | iscsi-initiator-utils multipathd nvme-cli nfs-utils |
| ObjectScale | 1.2.x | - |
Notes:
- Install only the OS dependencies for the protocols you use (e.g., skip
nvme-cliif NVMe isn’t used). - Always use the CSM and Kubernetes API for storage operations.
- Changes made outside these tools (like using storage array GUIs or CLIs) won’t be reflected in Kubernetes, leading to inaccurate metadata and state information.
- If you make external changes, manually update the Kubernetes cluster to keep everything in sync.
Supported Container Orchestrator Platforms
| Platform | Version |
|---|---|
| Kubernetes | 1.30, 1.31, 1.32 |
| Red Hat OpenShift | 4.17, 4.18 |
| Mirantis Kubernetes Engine | 3.7.x |
Notes:
- Self-certify unsupported orchestrator platforms/versions using Cert-CSI. Use platforms that haven’t reached end of life.
- CSM Authorization Server v1 is not supported on Red Hat OpenShift. It can be installed on standard Kubernetes and used with a Dell CSI Driver enabled with CSM Authorization on Red Hat OpenShift.
- CSM Authorization Server v2 is supported on Red Hat OpenShift.
OpenShift Virtualization
OpenShift Virtualization 4.17 supports storage profile operations only for the following storage systems: PowerFlex, PowerMax, PowerStore, PowerScale.
Tested Host Operating Systems
Container storage module doesn’t officially support specific operating systems, but the following are known to work:
- RedHat CoreOS (RHCOS) as supported by OpenShift Container Platform
- RHEL 8+
- SLES 15SP5
- Ubuntu 22.04
Notes:
- Ensure the host OS/version aligns with Dell Storage platform support. Check E-Lab Navigator for details.
- OS versions not listed must be self-certified using Cert-CSI. It’s recommended to use OS versions that haven’t reached end of life.
