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.

Tape Storage

    Kryten - Hardware

    • IBM TS4500 tape library
    • Six IBM TS1155 tape drives capable of storing 15TB uncompressed data per tape at the transfer speed of 360MB/s
    • One L25 library manager rack housing tapes, tape drives and control equipment
    • Two S25 storage racks housing tapes
    • A capacity of 2500 tape slots


    Backup and long term storage data for various SNIC projects and resources are stored in the tape library. It's also used for long term storage of data in the WLCG project.


    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.


    Swestore is Research Data Storage Infrastructure operated by the Swedish National Infrastructure for Computing (SNIC).

    The resources provided by Swestore are made available through open procedures such that the best Swedish research is supported and new research is facilitated. The purpose of Swestore allocations, granted by Swedish National Allocations Committee (SNAC), is to provide large scale data storage for “live” or “working” research data, also known as active research data.
