AST 2500) with dedicated RAM and Flash ▶ Provides ▶ System Power/thermal control ▶ Out of Band management ▶ IPMI, REST, etc ▶ Data collection ▶ Debug ▶ GUI and Command line ▶ Interfaces to Host/OCC ▶ System error logging ▶ Based on OpenEmbedded technologies built via Yocto ▶ Embedded Linux stack ▶ Linux Kernel 4.10….4.18, Yocto 2.3…2.6, python, SSH ▶ Applications communicate via D-Bus ▶ Users communicate via REST, IPMI and GUI ▶ Reports externally to management entity ▶ No customer network functional interaction What is the OpenBMC Project Free open source software management Linux distribution designed for the embedded environment … OpenPOWER Eco-system Enablement Industry Collaboration Quality Solutions Reduce Redundant Effort Openness -- provides proof of security Part of Linux Foundation What is OpenBMC ▶ 100% compatible with OpenPOWER Hostboot/Opal/OCC ▶ Aka BIOS ▶ https://github.com/open-power/op-build ▶ Can simply be a reference implementation ▶ Currently runs on… ▶ Barreleye, S822LC, S822LC For HPC, P8 Reference ▶ Witherspoon -- P9 AC922LC Power AI and CORAL ▶ P9 reference boards ▶ AST2400 and AST2500 BMC hardware Core Infrastructure of the OpenBMC Project Control the Functions in your OpenBMC… ▶ Built on Yocto-Linux ▶ YAML/XML input for system configuration Infrastructure at the ready ▶ Process management Systemd ▶ IPC via D-Bus ▶ External Interfaces via REST, IPMI, GUI ▶ Journaling for Trace/debug ▶ Code update ▶ Code
