     A simple flat cluster with two node types

A Sample config.yml file;

The config file below defines two compute node templates and multiple network
templates.  The sample cluster can be configured with the provided config.yml file.
The deployer node needs to have access to the internet for accessing packages.
Internet access must then be provided via one of the dotted line paths shown
in the figure above or alternately via a wireless or dedicated interface.

Various OpenPOWER nodes can be used such as the S821LC.  The deployer node can be OpenPOWER
or alternately a laptop which does not need to remain in the cluster.  The data switch can be
Mellanox SX1700 or SX1410. The management switch must be a
Lenovo G8052 switch::

    # This sample configuration file documents all of the supported key values
    # supported by the genesis software.  It can be used as the basis for creating
    # your own config.yml file.  Note that keywords with a leading underscore
    # can be changed by the end user as appropriate for your application. (e.g.
    # "_rack1" could be changed to "base-rack")
