Prototype of National Federated Storage


R&D project to develop, prototype and implement a federated data storage system between Russian WLCG sites and University clusters and to demonstrate how data reconstruction and analysis payloads (for at least two LHC experiments ATLAS and ALICE) and for bioinformatics applications (genome sequencer group of NRC-KI) running on WLCG facilities, on super-computers and Academic cloud can access federated data. This project intends to implement a federated distributed storage for all kind of operations such as read/write/transfer(3rd party)-RWT, and access via WAN from heterogeneous computing resources, such as Grid centers, University clusters, academic and commercial clouds and supercomputers.

Technologies to be evaluated

Computing Facilities

  • Grid centers
  • University clusters
  • Academic cloud(s)
  • Supercomputers

Technical requirements



  • PerfSonar should be insttaled on each participating site


List of Tests

  • Experiments tests
    • ALICE
      • add short desc or ref to doc

Test results

Results are stored at You'll need RDIG CA root certificate (in your browser or at the machine, depending on the access method) and your personal certificate (browser/machine too).

People with r/w access:

  • Eygene Ryabinkin
  • Andrey Zarochentsev
  • Andrey Kiryanov

People with r/o access:

  • Alexey Klimentov
  • Dmitry Krasnopevtsev

More people can be added, drop a letter to, tell why do you need access and attach your X.509 certificate (BEWARE: not the private key).

Access to results

Use plain browser for read-only operations.

Use Davix for X.509-powered read-write access:

Currently we don't allow for anonymous access at all.
