SNIC Storage is a working group within a SNIC, that has assignment to create and operate research data storage infrastructure and research data services.

In scientific areas such as high energy physics (the Large Hadron Collider at CERN), climate modelling, bioinformatics, bioimaging etc., the demands for research data storage and research data services are increasing dramatically. To serve these and other user communities, SNIC has appointed this working group to design a storage strategy, taking into account the research community needs. For more information please contact [support at swestore.se]


The aim of this nationally accessible storage (Swestore) is to build a robust, flexible and expandable system that can be used in most cases where access to large scale storage is needed. To the user it should appear as a single large system, while it is desirable that some parts of the system are deployed and distributed across SNIC centres to benefit from the advantages of, among other things, locality and redundancy effects. We continuously investigate new technologies that are suitable to implement Swestore. This storage solution is intended as a versatile short and medium term storage (one to four years allocations), for large-scale research data. It is intended and best suitable for so called “warm” data that is not analysed or processed right now but it is still relevant for the active research project. Project allocations are usually not backed up unless agreed differently and all files, i.e. digital objects, exist in two replicas in two geographically different locations. The main purpose of this type of storage is to offload the fast storage (Center Storage) during the active research phase and to move data from and to SNIC Centers.

Today, Swestore is available as two separate services built on dCache and iRODS technology, and they exist under the names, Swestore-dCache and Swestore-iRODS.
