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

It is best if the storage network and the management network each use separate contiguous ranges of IP addresses. Use the following table to determine how many IP addresses you need for your NetApp HCI 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

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
10.255.0.0/16 Docker swarm ingress network
169.254.100.1/22 Docker bridge network
169.254.104.0/22 Docker bridge network
