9. Evaluation of CTA for use at Fermilab

Ren Bauer (Fermi National Accelerator Lab. (US))

09/03/2022, 16:00

CTA

Fermilab is the primary research lab dedicated to particle physics in the United States and also is home to the largest archival HEP data store outside of CERN. Fermilab currently employs a HSM based on Enstore, a Fermilab product, and dCache, for tape and disk, respectively. This Enstore+dCache HSM manages nearly 300 PB of active data on tape. Because of the necessary development work to...

34. An HTTP Rest API as SRM replacement for tape access

Cedric Caffy (CERN)

CTA

Imagine a world where SRM is no longer needed to dialog with tape storage systems. A world where only one standard protocol can be used across the entire WLCG to access tape storage systems.

This dream will soon become reality on EOS...

After several discussions about the specifications of the new WLCG tape REST API, a prototype of the final API has been developed in EOS.

In order to...

28. CTA at RAL

15 Minutes

This talk will present details of the deployment of Antares, the EOS-CTA service at RAL Tier-1, which replaces Castor.

7. dCache integration with CTA

Mr Tigran Mkrtchyan (DESY)

CTA

20 Minutes

The ever increasing amount of data that is produced by modern scientific facilities like EuXFEL or LHC puts a high pressure on the data management infrastructure at the laboratories. This includes poorly shareable resources of archival storage, typically, tape libraries. To achieve maximal efficiency of the available tape resources a deep integration between hardware and software components...

39. CTA tape format support : BoF discussion

Michael Davis (CERN)

09/03/2022, 17:20

CTA

CTA uses the same tape format as CASTOR. There is interest from the community in adding support to read (but not write) tapes in alternate formats, such as OSM and Enstore. The main use case is to allow sites to migrate from their existing tape storage system to CTA without needing to physically repack all of their tapes.

This BoF session will be a round-table for stakeholders with an...
