  **Project and user**
  A project, sometimes referred to as a*tenant*, is a unit of ownership. Most resources, such as 
  virtual machines, volumes, and images, belong to a specific project. Only users with a role 
  assignment for a specific project can work with the resources that belong to that project. The 
  ibm-default project is created during installation, but PowerVC supports the creation of more 
  projects for resource segregation. 
  
  When possible, it is recommended to create a user and project for the OpenShift 
  environment. 
  
  **High Availability**
  High Availability (HA) is a requirement for any production deployment. A crucial consideration 
  for HA is the removal of single points of failure (SPOFs). This reference architecture is highly 
  available at all layers (Hardware, PowerVM, PowerVC, and OpenShift). 
  
  **Hardware HA**
  You must take care to eliminate single points of failure at the hardware layer. The following 
  hardware fault tolerance recommendations are implemented in this architecture: 
  
  (cid:2) Redundant server power supplies that are connected to different power sources. 
  (cid:2) Redundant network adapters that are connected to redundant network switches. 
  (cid:2) Redundant Fibre Channel adapters that are connected to redundant SAN fabrics.
