      abstract     = {The SAGE2 project is a collaboration between industry, data
                      centres and research institutes demonstrating an
                      exascale-ready system based on layered hierarchical storage
                      and a novel object storage technology. The development of
                      this system is based on a significant co-design exercise
                      between all partners, with the research institutes having
                      well established needs for exascale computing systems, both
                      in terms of compute (exaFLOPS) and storage (exaBytes).In
                      this paper we present an overview of the system design
                      concepts and introduce some of the features of the object
                      storage system which have the potential to make applications
                      more efficient and simpler to use. The physical realisation
                      of a prototype, hosted at Forschungszentrum Jülich is also
                      detailed showing in detail the layered hierarchyWe also
                      present a case study of applications which have already been
                      ported, covering issues uncovered and how these have been
                      addressed in the codesign proves. Finally, we look at how
                      this suite of applications are being extended into different
                      regimes including machine learning to address a wider range
                      of use cases and how interfaces are being developed to allow
                      integration with other architectures.},
