ITERDB—The Data Archiving System for ITER

For ITER, acquiring, managing and archiving its data is an essential task. ITER is foreseen to produce up to one terabyte of data per pulse and several petabytes of data per year. All the produced data needs to be stored and managed. The stored data is expected to serve the data access needs of ITER researchers located both on the ITER premises as well as worldwide during ITERʹs lifetime and beyond. is a data management system being designed for centralized ITER data archival and data access. It is designed to manage and serve both unprocessed and processed data from the ITER plant systems and data analysis workflows. s paper, we report the ITER Data Archiving System software requirements and priorities that have been identified by working with ITER staff and a large number of stakeholders. We will describe the design challenges and the proposed solutions. We will also present the current state of the ITERDB software architecture design.
