  1. 1. Particulate magnetic tape for data storage and future technologies
    Mr Masahito Oyanagi (Recording Media Research Laboratories, Fujifilm Corporation)

    Storage & Filesystems

    Enterprise tape drives are widely used at major laboratories in the world, such as CERN, US DoE Labs, KEK and so on as well as data centers in commercial companies. Demands on capacity and speed of I/O inflate infinitely in the tape market. Not only drive technology but also media technology is the key for answering such future requirements. Fujifilm is the world-leading company in the market...

    Storage & Filesystems

    In March 2017 Echo went in to production at the RAL Tier 1 providing over 7PB of usable storage to WLCG VOs. This talk will present details of the setup and operational experience gained from running the cluster in production.

  4. 68. Storage for Science at CERN
    Dr Giuseppe Lo Presti (CERN)
    19/10/2017, 11:10
    Storage & Filesystems

    In this contribution the vision for the CERN storage services and their applications will be presented.
    Traditionally, the CERN IT Storage group has been focusing on storage for Physics data. A status update will be given about CASTOR and EOS, with the recent addition of the Ceph-based storage for High-Performance Computing.
    More recently, the evolution has focused on providing higher-level...

  5. 36. Managing cloudy dCache storage pools with Ansible.
    Ulf Bobson Severin Tigerstedt (Helsinki Institute of Physics (FI))

    Storage & Filesystems

    NDGF-T1 is transferring the dCache storage to a model whese dCache is no longer run by the sysadmin but run as a normal user. This enables centralized management of the software versions and their configs.
    This automation is done with 3 roles in Ansible and a playbook to tie them together.
    The end result is software running in an environment much like the cloud.

  6. 41. Cloud storage with the Dynafed data federator
    Dr Marcus Ebert (University of Victoria)
    19/10/2017, 11:50
    Storage & Filesystems

    We describe our use of the Dynafed data federator with cloud computing resources. Dynafed (developed by CERN IT) allows a dynamic data federation, based on the webdav protocol, with the possibility to have a single name space for data distributed over all available sites. It also allows a failover to another copy of a file in case the connection to the closest file location gets interrupted...

  7. 69. The Outlook for Archival Storage at CERN
    Michael Davis (CERN)
    19/10/2017, 12:15
    Storage & Filesystems

    The CERN Physics Archive is projected to reach 1 Exabyte during LHC Run 3. As the custodial copy of the data archive is stored on magnetic tape, it is very important to CERN to predict the future of tape as a storage medium.

    This talk will give an overview of recent developments in tape storage, and a look forward to how the archival storage market may develop over the next decade. The...
