If a container platform is deployed on a virtualization platform, you are advised to use the iSCSI protocol when the CSI is connected to SAN storage.
If the customer requires the FC, NVMe over FC, or NVMe over RoCE protocol, the virtualization platform needs to be configured. In this case, the customer’s virtualization team needs to provide technical support.
When NVMe over RoCE or NVMe over FC is used, the supported nvme-cli tool version is 1.9 or later. To query the version, run the nvme version command.
