What physical ports on unity are needed to use NFS with Unity CSI driver ?

Jump to solution

I would like to setup the CSI driver to use NFS volumes on NAS shares on the Unity. 

Currently I don't have iSCSI ports on our array. Is this a requirement? From below it seems to be that to use NFS iSCSI ports are a requirement ?

Requirements

  • Install Kubernetes or OpenShift 
  • Configure Docker service
  • Install Helm v3
  • To use FC protocol, host must be zoned with Unity array
  • To use iSCSI and NFS protocol, iSCSI initiator and NFS utility packages need to be installed

Hi suprtbowl100d,

I see some confusion here ..

You may need physical ports if FC/iSCSI protocol is used. To use NFS protocol, only nasServer and storage pool should be configured any other ports/iSCSI ports are not required.

Also, csi driver uses nasServer and not responsible for creating it, though it is a pre-req. csi-driver is like any other tool, so if you can export NFS share with others then its ok you can use it.

Hi Suprtbowl100d,

Sorry for the confusion here...

For iSCSI support all Kubernetes nodes must have the iscsi-initiator-utils package for CentOS/RHEL or open-iscsi package for Ubuntu installed, and the iscsid service must be enabled and running. To do this, run the systemctl enable --now iscsid command.

For NFS support all Kubernetes nodes must have the nfs-utils package installed to be able to mount/unmount NSF exports from the Unity array.

Thanks
Bryan

ok thanks for the reply Bryan.

I am specifically asking about the physical ports on the unity and what ports I need to use.

I just want to use NFS for the moment... Does that mean I do not need iSCSI ports on the Unity ?

I can use Ethernet ports which currently I have setup for connectivity to our NAS servers for exporting NFS shares?
