The bare metal nodes are "simulated" thanks to [https://github.com/openstack/virtualbmc Virtual BMC]. Ironic indeed uses the IPMI protocol to turn on/off/change the boot order of nodes.

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
  • 1 Ceph cluster for Cinder
  • 3 bare metal nodes for Ironic

In the second availability zone :

  • 3 compute nodes
  • 1 Ceph cluster


Lab architecture


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)

Resources

For the needs of the lab, the actual hardware used is :

  • 4 VMs for Openstack controllers on a workstation
  • 3 VMs acting as hyperconverged nodes in AZ1 on Hypervisor 1 (Supermicro X10SL7-F with Xeon E3-1265L v3, 32 GB RAM ECC DDR3)
  • 3 VMs acting as bare metal nodes in AZ1 on Hypervisor 2 (HP Elitedesk 800 g2 mini with Core i5-6500t, 32 GB RAM DDR4)
  • 3 VMs acting as hyperconverged nodes in AZ2 on Hypervisor 3 (Supermicro X9SCM-F with Xeon E3-1265L v2, 32 GB RAM ECC DDR3)

The bare metal nodes are "simulated" thanks to Virtual BMC. Ironic uses indeed the IPMI protocol to turn on/off/change the boot order of nodes.
