• Input received from LHCb, ATLAS and ALICE.
• Still pending for CMS

14:50 → 15:00 WLCG Service Report

Weekly FTS report, site-by-site action list.

It is proposed that the on-going LFC 1.5.10 and dCache 1.7 deployment issues are followed by the weekly joint operations meeting.

Additional actions are expectly shortly regarding Production Deployment of Distributed Database Services, e.g. LFC for LHCb, COOL services for ATLAS and LHCb.

15:20 → 15:40 File Transfer Performance and Reliability

The process for understanding file transfer performance issues, reliability and realistic targets.

Issues to be understood include:

• Stability of basic services involved;
• Clear monitoring information and error reporting;
• Possible interference and / or conflicts between concurrent activities (within a VO, between VOs etc.)
• Road-map for resolving these problems, with realistic targets by site & by VO.
