Virtual All-in-one Duplex Installation R3.0

Overview

The All-in-one Duplex (AIO-DX) deployment option provides a pair of high availability (HA) servers with each server providing all three cloud functions (controller, worker, and storage).

An AIO-DX configuration provides the following benefits:

  • Only a small amount of cloud processing and storage power is required

  • Application consolidation using multiple containers or virtual machines on a single pair of physical servers

  • High availability (HA) services run on the controller function across two physical servers in either active/active or active/standby mode

  • A storage back end solution using a two-node CEPH deployment across two servers

  • Containers or virtual machines scheduled on both worker functions

  • Protection against overall server hardware fault, where

    • All controller HA services go active on the remaining healthy server

    • All virtual machines are recovered on the remaining healthy server

Note

If you are behind a corporate firewall or proxy, you need to set proxy settings. Refer to Docker Proxy Configuration for details.

Note

By default, StarlingX uses IPv4. To use StarlingX with IPv6:

  • The entire infrastructure and cluster configuration must be IPv6, with the exception of the PXE boot network.

  • Not all external servers are reachable via IPv6 addresses (for example Docker registries). Depending on your infrastructure, it may be necessary to deploy a NAT64/DNS64 gateway to translate the IPv4 addresses to IPv6.

  • Refer to the StarlingX IPv6 Deployment guide for details on how to deploy a NAT64/DNS64 gateway to use StarlingX with IPv6.
