    Rongqiang Zhang Bringing the OpenBMC for Platform Manage- ment System in Telco Cloud Helsinki Metropolia University of Applied Sciences Master of Engineering Information Technology Master’s Thesis 30 Apr 2019 Abstract Rongqiang Zhang Author(s) Bringing the OpenBMC for Platform Man-agement System in Title Telco Cloud Number of Pages 88 pages + 0 appendices Date 30 Apr 2019 Degree Master of Engineering Degree Programme Information Technology Specialisation option Networking and Services Ville Jääskeläinen, Head of Degree Program Instructor(s) Zinaida Grabovskaia, PhL, Senior Lecturer Antti Koivumäki, Senior Lecturer Ari Helminen, Business Manager The current platform management system in Telco cloud infrastructure is based on closed firmware stack. With the upcoming 5G, this closed firmware stack has created several tech- nology and business problems. The major problems are hardware-software vendor lock-in, long lead time for feature development and bug fixing, and security risks. The objective of this study is to evaluate the possibility to bring an Open Source software stack for platform management system and baseboard management controller in Telco cloud. The study was divided into 3 parts. First part is to analyse the current state and project specification. Second part is to introduce and evaluate the OpenBMC, an open source soft- ware stack for the objective of this study. Third part is Proof of Concept to run OpenBMC on Telco.

Our Leadership Computing Facility celebrated its 25th anniversary and launched Summit, an IBM system that is currently the world’s fastest and most AI-compatible computer, marking the third time that ORNL has claimed the number one spot on the coveted TOP500 list; we acquired a vendor for our first exascale machine, Frontier, to be delivered in 2021; and we once again hosted the best and brightest from the computing and data worlds at the 2018 Smoky Mountains Conference in Gatlinburg, Tennessee. 2018’s theme, “the integration of experiment, data analytics, and modeling and simulation into instruments for discoveries in science and engineering,” proved a fertile one for discussion as our esteemed lineup of speakers brought us up to speed on the states of the art in both computing and big data. With more than 180 people registered, 15 great sponsors, and more Data Challenge participants than we have ever had, 2018 marked the biggest SMC on record. The conference has come a long way since its humble beginnings in 2003, when 45 participants descended on Fall Creek Falls in Pikeville, Tennessee.

Sander Abstract—Modern physics experiments often utilize FPGA- and calibration tasks can be handled in software. Quicker based systems for real-time data acquisition. Integrated analog implementation time and features such as advanced arithmetic electronics demand for complex calibration routines. Further- support with hardware division or floating-point calculations more, versatile configuration and control of the whole system is a key requirement. Beside low-level register interface to the FPGA, come in handy for these tasks. Also, remote monitoring also access to I2C and SPI buses is often needed to configure the and control access to DAQ systems is mandatory for larger complete system. Calibration through an FPGA is inflexible and experiments that can contain dozens of such platforms and yields a complex hardware implementation. On the contrary, measure over a longer time period. calibration through a remote system is possible but considerably We designed and implemented a versatile control framework slower due to repetitive network accesses. By using SoC-FPGA solutions with a microprocessor, more sophisticated configuration for DAQ systems based on heterogeneous MPSoCs. Our devel- and calibration solutions, as well as standard remote access opment primarily targets the application domains concerning protocols, can be efficiently integrated in software. the readout of superconducting sensors and quantum bits.

Over the past decade, IT device manufacturers and service providers have struggled with the OpenBMC is built on a standard Linux distribution that challenges of managing datacenters with non-standard, simplifies integration and porting to different offerings. Many proprietary Baseboard Management Controller (BMC) firmware. modular components are available that allow developers to Customers who rely on these assets to run their business were build a BMC solution and create advanced management often left frustrated because they had insufficient control over features. With support for OpenBMC coming largely from their datacenters. With BMC failures being one of the largest Facebook, Microsoft, Google, and IBM, the solution in the factors in datacenter reliability, customers had to rely community addresses the requirements for cloud-scale server completely on third-party BMC firmware providers. This often management. However, today’s embedded management resulted in poor reliability, costly schedules, lack of landscape spans across the entire IT infrastructure, across customization, slow issue resolution, and feeling vulnerable to multiple CPU architectures, and has a range of custom security threats at any given time. Furthermore, businesses features tailored to various customer segments.
