  This architecture includes the following PowerVC recommendations: 
  
  (cid:2) Each Host Group (Availability Zone) must include more that one server to allow Simplify 
  Remote Restart, DRO, and Host evacuation. 
  
  (cid:2) Automated Remote Restart must be enabled at the Host Group level. When an error 
  causes a server outage, a virtual machine that is configured with the remote restart 
  capability can be restarted automatically on a different physical server. 
  
  Figure 5-8 shows how Simplify Remote Restart is working with HMC configuration.
