Introduction openEuler 21.09 Technical White Paper 02 openEuler has evolved from a simple server operating system (OS) into a digital infrastructure OS that fits into any server, cloud computing, edge computing 09 Technical White Paper 04 02/ Platform Architecture openEuler 21.09 Technical White Paper 05 System Framework openEuler is an innovative open source OS platform built on kernel innovations and a solid online services to run reliably based on their higher service priorities. • EulerFS: A new file system is designed for non-volatile dual in-line memory modules (NVDIMMs). It uses technologies such as

Easy operation and maintenance ○ High performance ● CEPH ○ Complex and Large amount of codes ○ system maintenance are difficult in corner cases ○ Performance requirements cannot be metAgenda Why develop performance optimizations RAFT protocol Zero data copy pre-created file poolCURVE file system File service middleware Upper-layer applications can access file data in storage pools through interfaces of Curve file systems ● System operation and maintenance ○ Further improve tools for installation/monitoring/maintenance ○ dashboard ● Cloud Native ○ Using CURVE file system in KubernetesCURVE community

consistent, & secure c. CREATE OUR SINGLE REPOSITORY OF TRUTH FOR THE ENTIRE SYSTEM i. ALL parts (code & environments) of the system are shared in a version control repository ii. Version control is for When a change causes the build or automated tests to fail: 1. No new work is allowed to enter the system until the problem is fixed. 2. Bring in whatever help is needed to resolve the problem iii. Prioritize tests of the integrated system as a whole 3. Work towards single-piece flow iii. Trunk & state of Deployment Pipeline represents & communicates the current state of the system iv. Modified Definition

Technical White Paper System Framework openEuler is used mainly for servers. It consists of the basic acceleration library, virtualization, kernel, driver, compiler, system tool, OpenJDK, and other expansion etMem: unified management of various memory and storage media, and smooth expansion of system capacity • Live kernel upgrade: quick, hitless fixes of kernel vulnerabilities Cloud base: • StratoVirt iSula Compilers Apps Desktops UKUI/DDE/Xfce DB Web Resource orchestration Messaging middleware Live kernel upgrade File systems Chips and peripheral drivers Linux Kernel 5.10 Computing architecture
