Storage I/O and Data Management for Exascale Architectures

The EU-funded IO-SEA project plans to provide a novel data management and storage platform for exascale computing based on object stores, hierarchical storage management and on-demand provisioning of storage services. The platform will efficiently make use of storage tiers, including non-volatile memory express (NVMe) and non-volatile random-access memory (NVRAM), all the way down to tape-based technologies. Use of ephemeral data nodes and data accessors should allow users to flexibly operate the system using various well-known data access paradigms. These ephemeral resources will eliminate the problem of treating storage resources and system components as static. The newly developed data management methods could be applied to data-intensive applications over exascale platforms.
