Bare metal Standard with Controller Storage Installation R2.0¶
Overview¶
The Standard with Controller Storage deployment option provides two high availability (HA) controller nodes and a pool of up to 10 compute nodes.
A Standard with Controller Storage configuration provides the following benefits:
A pool of up to 10 compute nodes
High availability (HA) services run across the controller nodes in either active/active or active/standby mode
A storage back end solution using a two-node CEPH deployment across two controller servers
Protection against overall controller and compute node failure, where
On overall controller node failure, all controller HA services go active on the remaining healthy controller node
On overall compute node failure, virtual machines and containers are recovered on the remaining healthy compute nodes

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.
