One region, two availability zones
This Openstack Lab is composed of one region (fr1) and two availability zones (az1 and az2).
In the first availability zone :
- 3 compute nodes (aka hypervisors) for Nova wihtin a Nova Cell called cell1
- 1 Ceph cluster for Cinder and Glance
- 3 bare metal nodes for Ironic
In the second availability zone :
- 3 compute nodes wihtin a Nova Cell called cell2
- 1 Ceph cluster (Cinder only)
Networks
The different networks are :
- fr1-az1 : provider network in AZ1 (flat, i.e. without VLAN, shared, i.e. available for everybody and external, i.e. managed outside Openstack)
- fr1-az2 : provider network in AZ2
- ironic : external VLAN for bare metal nodes (only available in AZ1)
- octavia : external VLAN for Octavia management (only available in AZ1)

The bare metal nodes are "simulated" thanks to Virtual BMC and Sushy-tools. Ironic uses among others the IPMI or Redfish protocol to turn on/off/change the boot order of nodes.
