Support Matrix
Storage Platforms
| Prerequisites | PowerStore | PowerScale | PowerFlex | PowerMax | Unity XT | 
|---|---|---|---|---|---|
| Version | 3.6, 4.0, 4.1, 4.2 | OneFS 9.4, 9.5.0.x (x >= 5), 9.7, 9.8, 9.9, 9.10, 9.11, 9.12  | 
          3.6.x, 4.5.x, 4.6.x | Unisphere 10.0, 10.1, 10.2 | 5.3.x, 5.4.x, 5.5 | 
| OS Dependencies | iscsi-initiator-utils multipathd nvme-cli nfs-utils  | 
          nfs-utils | SDC | iscsi-initiator-utils multipathd or powerpath nvme-cli nfs-utils  | 
          iscsi-initiator-utils multipathd nfs-utils  | 
      
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.
 
Container Orchestrator Platforms
| Platform | Version | 
|---|---|
| Kubernetes | 1.32, 1.33, 1.34 |

Tested Host Operating Systems
Container Storage Modules 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.
