2. Tools for the management of stored data and transfer of data: DPM and FTS

David Smith (CERN)

[presentation] As a part of the EGEE project the data management group at CERN has developed and support a number of tools for various aspects of data management: A file catalog (LFC), a key store for encryption keys (Hydra), a grid file access library (GFAL) which transparently uses various byte access protocols to access data in various storage systems, a set of utilities ...

3. File Transfer Service

[paper] A key feature of WLCG's multi-tier model is a robust and reliable file transfer service that efficiently moves bulk data sets between the various tiers, corresponding to the different stages of production and user analysis. We describe in detail the WLCG transfer service, both the tier-0 data export and the inter-tier data transfers, discussing the transition...

4. DPM Status and Next Steps

[paper/poster] The DPM (Disk Pool Manager) provides a lightweight and scalable managed disk storage system. In this paper, we describe the new features of the DPM. It is integrated in the grid middleware and is compatible with both VOMS and grid proxies. Besides the primary/secondary groups (or roles), the DPM supports ACLs adding more flexibility in setting file...

5. Recent Developments in LFC

[paper/poster] The LFC (LCG File Catalogue) allows retrieving and registering the location of physical replicas in the grid infrastructure given a LFN (Logical File Name) or a GUID (Grid Unique Identifier). Authentication is based on GSI (Grid Security Infrastructure) and authorization uses also VOMS. The catalogue has been installed in more than 100 sites. It is essential to...

6. GFAL and LCG-Util

Remi Mollon (CERN)

03/09/2007, 09:20

[paper/poster] GFAL, or Grid File Access Library, is a C library developed by LCG to give a uniform POSIX interface to local and remote Storage Elements on the Grid. LCG-Util is a set of tools to copy/replicate/delete files and register them in a Grid File Catalog. In order to match experiment requirements, these two components had to evolve. Thus, the...

7. Medical Data Management Status and Plans

Akos Frohner (CERN)

[paper/poster] The goal of the Medical Data Management (MDM) task is to provide secure (encrypted and under access control) access to medical images, which are stored at hospitals in DICOM servers or are replicated to standard grid Storage Elements (SE) elsewhere. In gLite 3.0 there are three major components to satisfy the requirements: The dCache/DICOM SE is a...
