What  is  a  BMC?  

!  BMC  –  Baseboard  Management  Controller  •  Runs  at  AC  plug  Gme  (no  power  switch)  •  Manages  Procs,  DIMMs,  Fans,  Power  Supplies,  etc  •  Reports  externally  to  management  soNware  

!  Current  suggested  BMC  on  Power:  AST2400  chip

What  is  OpenBMC  !  Provides  simplified  management  of:    

•  Environment    •  Inventory    •  Sensors  and  event  logs    

!  Based  on  OpenEmbedded  technologies  built  via  Yocto    !  Embedded  Linux  stack  

•  Linux  Kernel  4.4,  Yocto  1.8.1,  python,  SSH  

!  ApplicaGons  communicate  via  D-­‐Bus    •  Allows  any  user  overlay  

!  Users  communicate  via  REST

What  is  OpenBMC  

!  100%  compaGble  with  OpenPOWER  Hostboot/Opal  •  Aka  BIOS  •  h`ps://github.com/open-­‐power/op-­‐build  

!  Can  simply  be  a  reference  implementaGon  

!  Currently  runs  on…  •  Barreleye,  822LC  and  the  P8  Reference

OpenBMC  Dbus  Interface  Examples  

!  A`ach  an  interface,  get  the  benefits  

•  Org.openbmc.Service  !  Obtain  informaGon  about  the  service    !  “status”,  “informaGon”  

•  Org.openbmc.delete  !  The  Parent  interface  is  delete’able  

•  Org.openbmc.InventoryItem  !  ProperGes  for  all  inventory    !  “Fault”,  “Present”
