This setup uses two network cables on the compute nodes for connectivity to all NetApp HCI networks.

• Use the
NetApp HCI Installation Discovery Workbook
to configure your network before the installation.

This setup consolidates all traffic onto two physical, redundant ports, reducing the cabling and streamlining
network configuration.
This configuration requires that the storage, vMotion and any virtual machine network
segments use VLAN tagging.
The management network segment can use native or tagged VLAN; however,
native VLAN is the preferred mode so that NetApp Deployment Engine (NDE) can assign network resources in
an automated manner (Zero Conf).
This mode requires vSphere Distributed Switches (vDS), which require VMware vSphere Enterprise Plus
licensing.
Networking requirements before you begin
Here are highlights of prerequisites.

.
• Bond1G is a logical interface that combines 1GbE network ports on storage nodes and a management
interface on compute nodes. This network is used for NDE API traffic. All nodes must be able to
communicate over the management interface in the same L2 network.
• Bond10G is a logical interface that combines 10/25GbE ports and are used by NDE for beaconing and
inventory. All nodes must be able to communicate over the Bond10G interface with non-fragmented jumbo
frames.
• NDE requires at a minimum one manually assigned IP address on the Bond1G interface on one storage
node. NDE will be run from this node.
• All nodes will have temporary IP addresses assigned by NDE discovery, which is accomplished by
Automatic Private IP Addressing (APIPA).
During the NDE process, all nodes will then be assigned permanent IP addresses and any
APIPA assigned temporary IPs will be released.
• NDE requires separate networks for management, iSCSI and vMotion that are preconfigured on the switch
network.
Validate network readiness with NetApp Active IQ Config Advisor
To ensure network readiness for NetApp HCI, install the NetApp Active IQ Config Advisor 5.8.1 or later. This
network validation tool is located with other
. Use this tool to validate connectivity, VLAN
IDs, IP address requirements, switch connectivity and more.
