Determine the number of supported nodes for SAN configurations


The number of nodes per cluster supported by ONTAP varies depending on your version of ONTAP, the storage controller models in your cluster, and the protocol of your cluster nodes.

About this task

If any node in the cluster is configured for FC, FC-NVMe, FCoE, or iSCSI, that cluster is limited to the SAN node limits. Node limits based on the controllers in your cluster are listed in the Hardware Universe.

  1. Go to NetApp Hardware Universe.

  2. Click Platforms in the upper left (next to the Home button) and select the platform type.

  3. Select the check box next to your version of ONTAP.

    A new column is displayed for you to choose your platforms.

  4. Select the check boxes next to the platforms used in your solution.
