You configure virtual machine networks using vCenter. The default virtual machine network
(port group "VM_Network") in NetApp HCI deployments is configured without a VLAN ID. If
you plan to use multiple tagged virtual machine networks (VLAN IDs 200 and 201 in the
preceding example), ensure you include them in the initial network planning.
Network configuration and cabling options
You can use a two-cable network configuration for the H410C compute nodes, simplifying cable routing. This
configuration uses two SFP+/SFP28 interfaces plus an optional (but recommended) RJ45 interface for IPMI
communication. These nodes can also use a six-cable configuration with two RJ45 and four SFP28/SFP+
interfaces.
The H410S and H610S storage nodes support a network topology that uses four network ports (ports A
through D).
Compute nodes support three network topologies, depending on the hardware platform:
Configuration option Cabling for H410C
nodes
Cabling for H610C
nodes
Cabling for H615C
nodes
Option A Two cables using ports D
and E
Two cables using ports C
and D
Two cables using ports A
and B
Option B Six cables using ports A
through F
Not available Not available
Option C Similar to option B, but with native VLANs (or "access ports") on the switch for the
management, storage, and vMotion networks
Nodes that do not have the correct number of connected cables cannot participate in the deployment. For
example, you cannot deploy a compute node in a six-cable configuration if it only has ports D and E
connected.
You can adjust the NetApp HCI network configuration after deployment to meet infrastructure
needs. However, when you expand NetApp HCI resources, remember that new nodes must
have the same cable configuration as the existing compute and storage nodes.

Network configuration
NetApp HCI can utilize multiple different network cabling and VLAN configurations. The
first configuration, option A, uses two network cables for each compute node.
