DMTF Manageability StandardsRemoteClient Off-platform (Redfish) A RESTful interface for manageability (HTTP, JSON)In-band Includes resource models for systems, chassis,managers. Other SDO's have extended Redfish tomanage other type of platforms and services On-platform (PLDM over MCTP) MCTP - A route-able transport protocol for manageabilitymessages (connection independent)Out-of-band(Redfish)BIOSCPUNICNC-SIBMC FW PLDM - A bit-based request/response command model RDE - A PLDM model designed for devices to supportRedfish form

OCP Platform Manageability Direction OCP will use Redfish profiles to specify platform manageability The OCP Hardware Management projectInterface Will specify the manageability common across OCPplatforms Has approved the "OCP Baseline HardwareManagement rofile(s)TelcoProfile(s)Rack &PowerProfile(s) Other OCP projects Will create platform specific profilesHardware Mgmt Baseline Profile Profiles will extend the "Baseline HardwareManagement Profile" "OCP Server Profile" is available1opencompute.org/wiki/Hardware Management/SpecsAndDesigns
OCP San Jose Compute Node Successfully ran the Redfish Interop Validator testing against the "OCP BaselineHardware Management Profile" Demonstrated at OCP Summit (March 2018)OCP Server Profile
Enabling Interoperable Manageability OCP will prescribe platform manageability in machine readable JSON profile Implementers can use the profile to test conformance of an implementation Linux Foundation governs the open-source implementation of BMC firmware (OpenBMC)10
OCP San Jose Compute Node Incorporated OpenBMC The implementation passed the OCP Baseline HW Manageability Profile Demo’ed at OCP Regional Summit (Oct 2018, Amsterdam) Changes will be upstreamed to the OpenBMC repository1 Target Date: March 2019 available on GitHub1The Linux Foundation project

Mission: Develop an open source philosophy based ‘system firmware’(BIOS) modules, to support different Operating Systems and differentCPU silicon r Companies Contributing to OSF development: Microsoft, Intel,Google, Facebook, Lenovo, IBM, Two Sigma, ITRenew, 9 Elements,Cavium, AMD and many more.Major Work Streams: Open EDKII DXE core, Linux Boot, Core Boot,Silicon Interface Firmware Module, Intel FSP, AMD AGESA, ARM bootcode, HW platform module, Build tools, Automated test support, HWrequirements, etc.GitHub Repositories Collateral eekly OSF discussions : Architectural reviews, workstream progress,design reviews, agenda setting and other collaborative discussions onOSF development.

Proposed OpenRMC sub-project Rack The rack is the fundamental building block for the Data Center Rack Manager Controller (RMC) The RMC is fundamental to Data Center Management hierarchy The RMC can be located standalone, within power shelf, or within the switch Opportunity Common language/model between RMC and nodes (aggregation, etc.) Provide an open source reference RMCnodes
