Logistics OpenRMC is a subproject of the Hardware Managementproject Interim co-chairs: John Leung (Intel) and Alfie Lew (Inspur) Wiki Participation ARM, Microsoft, Facebook, Huawei, Inspur, Nokia, Intel, etc
StatusRegular meetings since Nov 2018 Facebook, Inspur and Microsoft have presented their RMC architectures Comparison of interfaces D88hxbSAxp5jCLKInitial draft of Northbound API (Redfish) 5FR71qc77e8-KRDMicrosoft submitted their Olympus RMC source The submittal will be updated with latest source changes https://github.com/opencomputeproject/Rack-Manager
Northbound API SpecificationRedfish-based Interfaces are specified by A set of URI to the resources Contents of JSON document (i.e. resource properties) Behavior of the interaction via the APIThe Northbound API shall be specified with An OCP Profile (resources and resource properties) An interface behavior specification
Redfish Resources from Service RootTop level resources Each top level resource may havesubordinate resources Each resource is represented as aJSON document (name-value pairs)Resource Path (URI)/redfish/v1 (Service lemetryService/redfish/v1/UpdateServiceOpenRMC RSD RMM Olympusx x x ? x x ?
Rack Manager Scope Vectors Manages a single rack or multiple racks? What rack-level manageability capabilities are supported? Reboot, power usage, power limit, temperature profile,firmware update? How do RMC Clients and RMC Services interact? During primary operational manageability or during debug? Via RMC abstraction or directly accessing server?
What rack-level manageability capabilities aresupported?Rack Level (northbound) Inventory Power-on/Reboot/ShutdownDrives the Power usagesouthboundInterface Power limitrequirements Temperature (profile?) Update firmware on all servers Status/HealthNode Level (southbound) Inventory Power-on/Reboot/Shutdown Power usage Power limit Temperature (profile?) Update firmware on all devices Status/HealthThe southbound Redfish interface shouldaligned with the OCP platform profiles
How do RMC Clients and RMC Services interact?Two extrema exists for the interaction models1. The RMC Client managesthe server, via the RMCabstraction model Does not see theunderlying complexity2. Upon failure, the RMCClient accesses the serverdirectlyRMC erver1. The RMC Client managesthe server, directly2. Upon failure, the RMCClient accesses the RMCdirectService, to reboot ordiagnose the server
