To discuss the (amazingly smooth) bringup process, Bryan and Adam were joined by members of the oxide team. Tales of adversity, re-work, un-re-work, and triumph!\nIn addition to Bryan Cantrill and Adam Leventhal, we were joined by Oxide colleagues Nathanael Huffman, Ian Sobering, Matt Keeter, and Aaron Hartwig.\nWe mentioned quite a few terms! Here's a helpful guide:\nCosmo - Oxide’s next-generation sled (currently in development) with an AMD Turin CPU\nGimlet - Oxide’s current-generation sled with an AMD Milan CPU\nTurin - AMD Epyc 9005 Series\nMilan - AMD Epyc 7003 Series\nGenoa - AMD Epyc 9004 Series (Oxide chose to skip this generation)\nSequencing - the precise control of when power rails are energized throughout a PCB\nSled - One of the (max 32) computers in an Oxide rack; a custom form-factor optimized for power and cooling efficiency\nIBC - Intermediate Bus Converter (Our 54VDC -> 12VDC converter)\nRoT - Root of Trust\nSP - Service Processor, the small computer (running Hubris) that allows for low-level control\nIgnition - An even lower-level control network for power management (including power of the SP)\nRuby - The AMD reference platform (Oxide has used this to prepare Cosmo software in advance of bringup)\nDC-SCM - https://www.opencompute.org/documents/ocp-dc-scm-spec-rev-1-0-pdf and OpenCompute standard form factor.\nGrapefruit - OCP DC-SCM form-factor board with our SP, RoT, and FPGA on it, used to replace the OCP DC-SCM baseboard management controller in the Ruby platform.\nCadence - Software Oxide previously used for PCB design\nAltium - Software Oxide now uses for PCB design\nHubris - Oxide’s embedded operating system, run on the SP and RoT\nHumility - The Hubris debugger\nPLM - Product Lifecycle Management – a class of software used for managing hardware BOMs\nBOM - Bill of Materials – the components required to build a hardware product\nRFK - Our colleague, Robert Keith (to distinguish him from our other colleague,...","thumbnail_url":"https://img.transistorcdn.com/cVYTzMGAZ_7gNn2i7iJYSuWlQOM4wHdJAzEuWrnLo9A/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS80OGI3/NjA5NWY4Yjc4NzE0/ZGI5ZmMzZmY4MjFi/YThiYy5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
