| cucumber | Hi there, I'm in early stages of planning to move to a HA environment. At this point I have Kilo and Liberty deployments (no HA), and I want to do a fresh install (in HA) of Ocata or something near that. I've being reading and I can't find useful information. I've read https://docs.openstack.org/ha-guide/ and https://docs.openstack.org/ocata/ha-guide-draft/, but I need something more high level at this point. I need to understand how m | 15:05 |
| cucumber | any server I will need for each service... 2 controllers (Neutron, HA-Proxy, Horizon, Glance, etc...), 1 (or 2?) Storage nodes (CEPH/Cinder) and several Compute Nodes (Nova). Is there anything I can read that can help me on that? | 15:05 |
