Hardware setup
The standard hardware requirements:
However, OpenStack does not require a significant amount of resources and the following minimum requirements should support a proof-of-concept high availability environment with core services and several instances:
[TODO: Verify that these numbers are good]
| Node type | Processor | Memory | Storage | NIC |
|---|---|---|---|---|
| controller node | 1-2 | 8 GB | 100 GB | 2 |
| compute node | 2-4+ | 8+ GB | 100+ GB | 2 |
For demonstrations and studying, you can set up a test environment on virtual machines (VMs). This has the following benefits:
- One physical server can support multiple nodes, each of which supports almost any number of network interfaces.
- Ability to take periodic "snap shots" throughout the installation process and "roll back" to a working configuration in the event of a problem.
However, running an OpenStack environment on VMs degrades the performance of your instances, particularly if your hypervisor and/or processor lacks support for hardware acceleration of nested VMs.
Note
When installing highly-available OpenStack on VMs, be sure that your hypervisor permits promiscuous mode and disables MAC address filtering on the external network.
