environmental statistics, such as the temperatures, currents, and voltages present on System Boards • Monitor and control power flow to the platform components such as System Boards and Control Boards • Power On Self Test and similar platform diagnostics • Logging and Notification for various platform events • The creation and destruction of Inter Domain Networks (IDNs) which allow for
TCP/IP connectivity between domains, across the platform's centerplane. • Support for a dual power-grid option Several
