The initial deployment of OpenStack will leverage a single commodity server, a HP DL380.  Its details are listed in the following table:

This deployment provides a compute capacity for 60 m1.medium instances or 30 m1.large instances.

Change the specifications in the table to meet your deployment. It's important to specify the expected capacity in the deployment document. For a basic rule of thumb, just divide the amount of available system memory by the instance memory. We'll talk more about accurately forecasting capacity in a later chapter.

There is one physical provider network in this deployment. SDN is provided in the tenant space by Neutron with the OVS ML2 plugin. Its details are listed in the following table:

Change the network addresses in this section to meet your deployment. We'll only use a single network interface for the all-in-one installation.

This deployment will use the RDO all-in-one reference architecture. This reference architecture uses a minimum amount of hardware as the basis for a monolithic installation of OpenStack, typically only used for testing or experimentation. For more information on the all-in-one deployment, refer to: https://www.rdoproject.org/.

For the first deployment, we'll just use the RDO distribution of the box. In later chapters, we'll begin to customize our deployment and add notes to this section to describe where we've diverged from the reference architecture.

The host system will need to meet the following requirements prior to deployment:

To enable the RDO repository, run the following command as the root user on your system:

# yum install -y https://rdoproject.org/repos/rdo-release.rpm
