• Four storage nodes require eight (8) Cat 5e/6 cables and eight (8) Twinax cables.
• Three compute nodes using the six-cable configuration require six (6) Cat 5e/6 cables and twelve (12)
Twinax cables.

IP address requirements
NetApp HCI has specific IP address requirements that depend on the size of your
deployment. Note that by default the initial IP addresses you assign to each node before
using the NetApp Deployment Engine to deploy the system are temporary and cannot be
reused. You need to set aside a second permanent set of unused IP addresses that you
can assign during final deployment.
Number of IP addresses needed per NetApp HCI deployment
The NetApp HCI storage network and management network should each use separate contiguous ranges of IP
addresses. Use the following table to determine how many IP addresses you need for your deployment:
System component Management
network IP
addresses needed
Storage network IP
addresses needed
vMotion network IP
addresses needed
Total IP addresses
needed per
component
Compute node 1 2 1 4
Storage node 1 1 2
Storage cluster 1 1 2
VMware vCenter 1 1
Management node 1 1 2
Witness Node 1 1 2 per Witness Node
(two Witness Nodes
are deployed for
each two-node or
three-node storage
cluster)
IP addresses reserved by NetApp HCI
NetApp HCI reserves the following IP address ranges for system components. When planning your network,
avoid using these IP addresses:
IP address range Description
10.0.0.0/24 Docker overlay network
10.0.1.0/24 Docker overlay network
