This section outlines network-related requirements that must be addressed before proceeding with the install.

3.1 IP Address Considerations

Nutanix recommends using static IP addresses for all nodes and CVMs. If the customer uses a DHCP server, ensure the assigned IP addresses are excluded from the DHCP pool.

You need to reserve two (2) IP addresses for each node in the cluster. The first IP is for the node itself, and the second is for the CVM that will run on that node.

Nutanix recommends using the 10.x.x.x or 172.x.x.x IP address schemes. Use the Network Information Checklist in the appendix to record this information before the install.

Community Edition reserves the IP range through for internal communication between nodes. Ensure the customer is not using this range for any other device on the network!

3.2 Firewall Considerations

The following table outlines which firewall ports must be open for Community Edition to communicate properly.
