Storage resources

Center Wide Storage (pfs)

The Center Wide Storage is a fast parallel file system, with 2 PB disk. It is running Lustre.

The machine is called Ransarn, but we generally refer to this system as 'pfs' on our webpage. It is available on all our clusters. As well as the normal home directory on afs, all users also have a home directory on the pfs. This is where you run your batch jobs from, since the batch system can access the pfs system, but not afs. The pfs system has NO BACKUP. In case the file system gets full, files that have been unused for some time might get deleted without warning.

The pfs system has been in use since 2014, and it was upgraded mid-2016, to a total of 2 PB of storage.

We have a page with more information about our filesystems.

Bender (Tape Storage)


  • IBM TS3500 tape library
  • Six IBM LTO Ultrium 5 tape drives capable of storing 1500GB uncompressed data per tape at the transfer speed of 140MB/s
  • One L53 library manager rack housing tapes, tape drives and control equipment
  • Four D53 drive racks housing tapes and tape drives
  • A capacity of 2000 tape slots


The tape storage facilities at HPC2N are based on an IBM TS3500 tape library which currently contains six IBM LTO Ultrium 5 tape drives, each capable of storing 1500GB  uncompressed data per tape at the transfer speed of 140MB/s. The library can hold 2000 tapes.

Archive and backup data for various SNIC projects and resources are stored in the tape library. It's also used for data archiving in the WLCG project.


The hardware in the Swegrid project is financed by a donation from the Knut and Alice Wallenberg foundation. Operational costs and personnel for support and maintenance are funded by the Swedish research council (VR) via SNIC. VR is also funding research targeted toward grid within the framework of Swegrid. SNIC is coordinator of Swegrid operation.

WLCG Storage

The Worldwide LHC Computing Grid (WLCG) is a global collaboration of computer centres. It was launched in 2002 to provide a resource to store, distribute and analyse the 15 petabytes (15 million gigabytes) of data generated every year by the Large Hadron Collider (LHC).

The Nordic Data Grid Facility (NDGF) is Tier-1 site for WLCG, with storage capacity and support for the Grid. HPC2N is a Tier-1 node, providing storage (dCache Pools) and computing services.

Storage: 8 DL32S, each with 7 TB. 5 Sun X4540, each with 36 TB.

In use since: 2007/2009.
