Supported networking changes

Contributors netapp-mwallis netapp-amitha Download PDF of this page

After you deploy NetApp HCI, you can make limited changes to the default networking configuration. However, certain settings are required for smooth operation and proper network detection. Changing these settings will cause unexpected behavior, and might prevent you from expanding compute and storage resources.

After you deploy your system, you can make the following changes to the default network configuration in VMware vSphere as dictated by your network requirements:

  • Change vSwitch names

  • Change port group names

  • Add and remove additional port groups

  • Change the vmnic interface failover order for any additional port groups you have added

H300E, H500E, H700E and H410C compute nodes

NetApp HCI expects the following network configuration for H300E, H500E, H700E and H410C nodes.

The following is a six-interface configuration with VMware vSphere Distributed Switching (VDS). This configuration is only supported when used with VMware vSphere Distributed Switches, and requires VMware vSphere Enterprise Plus licensing.

H610C compute nodes

NetApp HCI expects the following network configuration for H610C nodes.

This configuration is only supported when used with VMware vSphere Distributed Switches (VDS), and requires VMware vSphere Enterprise Plus licensing.

Ports A and B are unused on the H610C.
