Inquiry Regarding NetApp ONTAP Configuration Maximums for Kubernetes/OpenShift Environments

Hi Team,

I am inquiring about the configuration maximums for NetApp ONTAP storage, specifically in the context of Kubernetes and OpenShift environments.

My focus is on the following limits:

  • The maximum number of NFS shares that can be created on an ONTAP system.

  • The maximum number of Block Volumes (e.g., iSCSI/FC LUNs) that can be created on an ONTAP system.

  • The maximum supported size of a single Block Volume on an ONTAP system.

The background for these questions is to understand the physical storage constraints that apply to Kubernetes/OpenShift users. When users request storage space via a Persistent Volume Claim (PVC), the request (including the desired Persistent Volume (PV) size) is passed from the container platform layer to ONTAP through Trident, NetApp's CSI Driver.

While Kubernetes/OpenShift does not impose inherent limits on the count or size of PVCs/PVs, the underlying hardware storage system's limitations will ultimately govern these maximums. Therefore, I need to know the specific configuration maximums of ONTAP to inform our planning and deployment.

Thank you for your assistance.
