IO-SEA

IO-SEA aims to provide a novel data management and storage platform for exascale computing based on hierarchical storage management (HSM) and on-demand provisoning of storage services. The platform will efficiently make use of storage tiers spanning NVMe and NVRAM at the top all the way down to tape-based technologies. System requirements are driven by data intensive use-cases, in a very strict co-design approach. The concept of ephemeral data nodes and data accessors is introduced that allow users to flexibly operate the system.

The ZDV will focus, besides other, inside this project on optimizing the open source object storage system MOTR, working on in-situ analysis and near-storage processing, as well as failure management. The ZDV will also bring in its expertise on HSM, data placement, and ephemeral storage systems.

Funding

IO-SEA has received funding from the European High-Performance Computing Joint Undertaking (JU) under grant agreement No 955811. The JU receives support from the European Union’s Horizon 2020 research and innovation programme and France, the Czech Republic, Germany, Ireland, Sweden and the United Kingdom.

The project runs from April 2021 to March 2024.
