[HCI 1.6] Supported networking changes

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

NetApp HCI requires that the following vmk to vmnic interface mappings be in place.

Physical interface	VSS six-cable compute virtual interfaces	VDS six-cable compute virtual interfaces	VDS two-cable compute virtual interfaces
Management interface	vmk0: vmnic2, vmnic3	vmk0: vmnic2, vmnic3	vmk0: vmnic1, vmnic5
vMotion interface	vmk1: vmnic0, vmnic4	vmk3: vmnic0, vmnic4	vmk3: vmnic1, vmnic5
iSCSI-A interface	vmk2: vmnic1	vmk1: vmnic5	vmk1: vmnic1
iSCSI-B interface	vmk3: vmnic5	vmk2: vmnic1	vmk2: vmnic5
