This paper summarizes the efforts over the last 3-4 years in providing symmetric active/active high availability for High-Performance Computing (HPC) system services. This work paves the way for high-level reliability, availability and serviceability in extreme-scale HPC systems by focusing on the most critical components, head and service nodes, and by reinforcing them with appropriate high availability solutions. This paper presents the accomplishments in the form of concepts and respective prototypes, discusses existing limitations, outlines possible future work, and describes the relevance of this research to other, planned efforts.
