Five virtual machines(VMs) are created with the Red Hat Enterprise Linux 8.4 operating system running on each one. Each of these VMs is configured with datastores that are mapped to the PowerFlex volumes. Upstream Kubernetes cluster v1.21.5 is built with one control plane node and four worker nodes using these VMs. PowerFlex CSI driver v2 is installed on the control plane node. This installation is done using Helm charts and Dell CSI Helm installer. PowerFlex SDC is installed on each of the worker nodes to communicate and consume PowerFlex-based storage volumes that are automatically provisioned by the CSI driver to meet the container’s storage requirement.

PowerFlex CSI 1.4 onwards does not create any storage classes as part of the driver installation. It is therefore necessary to create additional storage classes during CSI installation using the sample YAML file from the
The following storage classes were created in the lab to meet the SQL MI storage requirements:
NAME PROVISIONER RECLAIMPOLICY VOLUMEBINDINGMODE ALLOWVOLUMEEXPANSION AGE
vxflexos (default) csi-vxflexos.dellemc.com Delete WaitForFirstConsumer true 106d
vxflexos-xfs csi-vxflexos.dellemc.com Delete WaitForFirstConsumer true 106d

vxflexos-xfs-sql-datalogs csi-vxflexos.dellemc.com Delete WaitForFirstConsumer true 105d
Note: Follow the compatibility matrix and the latest available CSI version before planning and configuring the PowerFlex platform. For more information about how to deploy PowerFlex CSI Driver, see and ensure that the prerequisites are met before the installation.
