Support Matrix

Storage Platforms

Platform Version OS Dependencies
PowerStore 3.5, 3.6, 4.0, 4.1 iscsi-initiator-utils
multipathd
nvme-cli
nfs-utils
PowerScale OneFS 9.4, 9.5.0.x (x >= 5), 9.7, 9.8, 9.9, 9.10, 9.11 nfs-utils
PowerFlex 3.6.x, 4.5.x, 4.6.x SDC
PowerMax Unisphere 10.0,10.1,10.2 iscsi-initiator-utils
multipathd or powerpath
nvme-cli
nfs-utils
Unity XT 5.3.x, 5.4.x, 5.5 iscsi-initiator-utils
multipathd
nfs-utils

Notes:

  • Install only the OS dependencies for the protocols you use (e.g., skip nvme-cli if 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.
  • Use SFTP to fix mismatches between PowerFlex SDC’s scini kernel module and OpenShift’s RHEL kernel.

Container Orchestrator Platforms

Platform Version
Kubernetes 1.31, 1.32, 1.33
Red Hat OpenShift 4.18, 4.19
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.

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.
