Shuquan Huang 5d24943d57 Add how to use in Ironic Section 
Since Ironic is an integration project now. We should add one section
about it in Admin guide.
This commit is part of the bugfix since adding the whole section is
huge. This one is to add the sequence of how to use Ironic.

Bare Metal

The Bare Metal service provides physical hardware management features.

Introduction

The Bare Metal service provides physical hardware as opposed to virtual machines and provides several reference drivers which leverage common technologies like PXE and IPMI, to cover a wide range of hardware. The pluggable driver architecture also allows vendor-specific drivers to be added for improved performance or functionality not provided by reference drivers. The Bare Metal service makes physical servers as easy to provision as virtual machines in a cloud, which in turn will open up new avenues for enterprises and service providers.

System architecture

The Bare Metal module is composed of the following components:

  1. A RESTful API service
  2. A conductor service
  3. Various drivers that support heterogeneous hardware
  4. A message queue
  5. A database for storing information about the resources

Bare Metal deployment

  1. PXE deploy process
  2. Agent deploy process

Use Bare Metal

  1. Install Bare Metal service.
  2. Setup Bare Metal driver in the compute node's nova.conf.
  3. Setup TFTP folder and prepare PXE boot loader file.
  4. Prepare the baremetal flavor.
  5. Register the nodes with correct drivers.
  6. Configure the driver information.
  7. Register the ports information.
  8. Use nova boot to kick off the baremetal provision.
  9. Check nodes' provision state and power state.
