« Lab architecture » : différence entre les versions

Version du 21 décembre 2022 à 11:13

This Openstack Lab is composed of one region (fr1) and two availability zones (az1 and az2).

In the first availability zone :

In the second availability zone :

Lab architecture

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)

Networks

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.
