22. Evaluation of gluster file system at IHEP

Dr Yaodong CHENG (Institute of High Energy Physics,Chinese Academy of Sciences)

5/4/11, 9:15 AM

Storage & Filesystems

GlusterFS is an open source, clustered file system capable of scaling to several petabytes and handling thousands of clients. At IHEP, we setup a testbed to evaluate the file system, including functionality, performance and current status. The advantages and disadvantages for HEP data processing are also disscussed.

25. Benefits of a virtualized approach to mass storage system

Dorin Daniel Lobontu (Karlsruhe Institute of Technology (KIT))

5/4/11, 9:45 AM

The talk will show the benefits of grouping a number of heterogeneous tape libraries into one virtual container of tape media and drives. The backup and archive applications send their data to this huge container which has all necessary mechanisms to control and access the tape resources(cartridges, drives, physical libraries).The implementation is based on an ibm software "Enterprise...

30. CASTOR status and development

Eric Cano (CERN)

5/4/11, 10:05 AM

Storage & Filesystems

We will present the performance achieved during data taking for the 2010 LHC run, including heavy ion run. The operational benefits reaped from the deployed improvement as well as the roadmap for further developments to consolidate the system and lower its deployment cost will be introduced. Our performance assessment for the new generation of Oracle tape drives – T10000C – will also be shown.

38. The DESY Grid-Lab, a detailed 'local access protocol' evaluation

Dmitry Ozerov (DESY)

5/4/11, 11:15 AM

Since mid of 2010, DESY IT is operating a performance evaluation facility of the size of a small gLite Tier II, the DESY Grid-Lab. Regular gLite software is deployed, allowing to execute commonly used LHC analysis jobs as well as applications provided by other communities. This presentation focuses on the comparison of different implementations of XROOTD, dCap as well as of the NFS4.1/pNFS...

39. Lustre at GSI

Thomas Roth (GSI)

5/4/11, 11:45 AM

Storage & Filesystems

Lustre has been employed with great success as the general purpose distributed file system for all experimental and theory groups at GSI. Currently there are 100 mio files stored on Lustre, and between batch nodes, interactive nodes and desktops there are ca. 500 clients with access to Lustre. Past issues with stability have been overcome by running the Lustre 1.8 version. Hardware upgrades...

54. Evaluation of distributed file systems using trace and replay mechanism

Mr Jiri Horky (Institute of Physics of Acad. of Sciences of the Czech Rep. (ASCR))

5/4/11, 12:15 PM

Storage & Filesystems

Reliable benchmarking of file systems is a complex and time consuming task when one has to test against a production environment to achieve relevant results. In case of the HEP community, this eventually leads to setting up a particular experiments' software environment, which could be a rather complicated task for a system administrator. To simplify this task, we developed an application ...

4. Foundation of the EOFS - support the lustre development

Walter Schon (GSI)

5/5/11, 4:30 PM

Storage & Filesystems

The European Open File Systems society is a non profit organisation to coordinate the future development of lustre. Founding members of the organisation are Universities, Supercomputing Centers and partners from industry. The next release of a lustre version is scheduled for summer 2011.
