  1. 58. Batch system data locality via managed caches
    Max Fischer (KIT - Karlsruhe Institute of Technology (DE))
    22/05/2014, 09:00
    Storage & Filesystems
    Modern data processing solutions increasingly rely on data locality to achieve high data access rates and scalability. In contrast the common HEP system architectures emphasis uniform resource pools with minimal locality, allowing even for cross-site data access. The concept for the new High Performance Data Analysis (HPDA) Tier3 at KIT aims at introducing data locality to HEP batch systems....

  2. 10. Ceph at CERN: one year on
    Dr Daniel van der Ster (CERN)
    22/05/2014, 09:25
    Storage & Filesystems
    Ceph was introduced at CERN in early 2013 as a potential solution to new use-cases (e.g. cloud block storage) while also providing a path toward a consolidated storage backend for other services including AFS, NFS, etc... This talk will present the outcome of the past year of testing and production experience with Ceph. We will present our real operations experience and lessons-learned, and...

  3. 33. Ceph at the UK Tier 1
    George Ryall (STFC)
    22/05/2014, 09:50
    Storage & Filesystems
    We are trialling the use of Ceph both as a file-system and as a cloud storage back end. I will present our experiences so far.

  4. 44. Update on CERN tape status
    German Cancio Melia (CERN)
    22/05/2014, 10:15
    Storage & Filesystems
    CERN stores over 100PB of data on tape via CASTOR and TSM. This talk will present the current status of the CERN tape infrastructure, with a particular focus on tape performance and efficiency and the status of the large media repacking exercise.

  5. 67. The DESY Big Data Cloud Service
    Mr Peter van der Reest (DESY)
    22/05/2014, 11:10
    Storage & Filesystems
    DESY -IT- has implemented a cloud storage service on the basis of dCache. The talk will describe architecture and service concepts.

  6. 60. Update on the bit-preservation Working Group
    German Cancio Melia (CERN)
    22/05/2014, 11:35
    Storage & Filesystems
    In this talk, we will provide an update of bit-level preservation WG activities, notable on the ongoing work on a set of recommendations and on a model for estimating long-term (10-20-30 years) archiving cost outlooks.
