NetApp HCI Requirements Edit on GitHub Request doc changes

Contributors ebarcott

The following are requirements for using NetApp HCI with NetApp Kubernetes Service (NKS). For more information about using NetApp HCI, see the official NetApp HCI documentation.

  • A NetApp HCI system successfully installed.

  • System size requirements:

    • 2x4 (2 compute nodes x 4 storage nodes) systems are not supported for production use. However, you can use these for demo work.

    • 3x4 (3 compute nodes x 4 storage nodes) systems are the minimum production system size we support.

    • 4x4 (4 compute nodes x 4 storage nodes) systems are the recommended minimum size.

    • NetApp HCI v1.6 or later.

  • Any version of vSphere supported by NetApp HCI.

  • vSphere distributed switches (VDS). We do not support installing to standard switches.

  • Management node 2.1 (requires updates from the 2.0 version).

  • Optional: Networks for NKS (and other services) pre-created in vCenter.

  • An NKS account.

  • An NKS API token.

    • This token authorizes the installer to access your NKS Organization.

    • To create an NKS API token, log in to NKS and click your user icon in the upper right-hand corner. Click Edit Profile then Add Token.

    • You can create the token at any time, even if you have not yet enabled cloud services on NetApp HCI.

If you have any of the following issues:

  • Replica pods deployed on different worker nodes. Trident’s guardrails prohibit the PVC Access Mode RWX with an iSCSI driver. In this case, no pods will come up.

  • Kubernetes Rolling Updates unsuccessful when a persistent volume is attached to the pod with iSCSI.

  • Ungraceful Kubernetes worker node loss due to multi-attach errors when RWO is configured.
