IP Address Planning

IP Address Planning

An IP address plan might be broken down into the following sections:

• Subnet router

• Control services public interfaces

• Object Storage cluster internal communications

• Compute and storage communications

• Out of band remote management

• In-band remote management

• Spare space for future growth

Subnet Router

Packets leaving the subnet go via this address, which could be a dedicated router or a nova-network service.

Control Services Public Interfaces

Public access to swift-proxy, nova-api, glance-api, and horizon come to these addresses, which could be on one side of a load balancer or pointing at individual machines.

Object Storage Cluster Internal Communications

Traffic among object/account/container servers and between these and the proxy server’s internal interface uses this private network.

Compute and Storage Communications

If ephemeral or block storage is external to the compute node, this network is used.

Out of Band Remote Management

If a dedicated remote access controller chip is included in servers, often these are on a separate network.

In-Band Remote Management

Often, an extra (such as 1 GB) interface on compute or storage nodes is used for system administrators or monitoring tools to access the host instead of going through the public interface.

Spare space For Future Growth

Adding more public-facing control services or guest instance IPs should always be part of your plan.
