Current FTS planning
Gavin McCance & Paolo Badino
ATLAS DDM session
14 September 2006
ATLAS DDM meeting
Enabling Grids for E-sciencE
INFSO-RI-508833
Plans: current
• Support– Support of CERN FTS instance and expert support for T1 instances– Patches and fixes as required– Inter-site export support to debug problems
• Next user-visible features– Delegation in FTS
Requires earlier deployment of new client version (to ensure backwards compatibility)
Schema to support the new features Planned for certification end September
– SRM v2.2 support Both SRM v2.2 and SRM v1.1 supported Cleaner error classes and messages Cleaner SRM interactions Planned for certification end October

Plans: next
• Better transfer service monitoring is then the highest development priority– We will not achieve the agreed WLCG service availability targets
without this We have a reasonable set of internal alarms and procedures to
check for problems on the FTS daemons or hardware• These need to be exposed to the tier-1 sites running FTS
However, the current overall service takes an unsustainable amount of ‘expert’ effort to debug inter-site problems
– Improved SAM tests SAM team already working on this
– Properly exposing the FTS view of the transfers Automatic reporting of rates / failure rates (per site / per VO) Alarms to CIC-on-duty and sites if channels go bad Top-3 things that are broken on your SRM

Plans: after
• Next things– Optimized SRM interaction: split preparation from transfer– Pre-staging support– Notification of finished jobs (so you don’t have to poll)– Catalog plug-ins
LFC in particular
– Examine current FTS deployment model (it doesn’t fit so well for all VOs) Improve FTS discovery model (“where do I send my job?”)
– Better service controls Make it easier to run and debug problems
– Work to support an open-source database is starting
