Storage Platforms

Prerequisites PowerStore PowerScale PowerFlex PowerMax Unity XT
Version 3.5, 3.6, 4.0, 4.1 OneFS 9.4, 9.5.0.x (x >= 5),
9.7, 9.8, 9.9, 9.10, 9.11		 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-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.

Container Orchestrator Platforms

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.
