SAGE (Percipient StorAGe for Exascale Data Centric Computing) is a EuropeanCommission funded project towards the era of Exascale computing. Its goal is todesign and implement a Big Data/Extreme Computing (BDEC) capable infrastructurewith associated software stack. The SAGE system follows a "storage centric"approach as it is capable of storing and processing large data volumes at theExascale regime.  SAGE addresses the convergence of Big Data Analysis and HPC in an era ofnext-generation data centric computing. This convergence is driven by theproliferation of massive data sources, such as large, dispersed scientificinstruments and sensors where data needs to be processed, analyzed andintegrated into simulations to derive scientific and innovative insights. Afirst prototype of the SAGE system has been been implemented and installed atthe Julich Supercomputing Center. The SAGE storage system consists of multipletypes of storage device technologies in a multi-tier I/O hierarchy, includingflash, disk, and non-volatile memory technologies. The main SAGE softwarecomponent is the Seagate Mero Object Storage that is accessible via the ClovisAPI and higher level interfaces. The SAGE project also includes scientificapplications for the validation of the SAGE concepts.  The objective of this paper is to present the SAGE project concepts, theprototype of the SAGE platform and discuss the software architecture of theSAGE system.
