7. PhEDEx transfers T0-T1
CMS-CCIN2P3 meeting 30/11/ C. Charlot

8. Concerns/questions Release deployment Disk cleanup Sam test
Some delay for installation
Disk cleanup
manual removal of unmerged files is innefficient
Sam test
Criteria for site removal
T1-T2 full connection matrix
Heavy load on storage system, difficulty to debug all sites at the same time
T1-T1 links and T1-associated T2s enables all possible routing
Contact/communication
More information needed on what’s ongoing from centralized production
xrootd SE
Would be interested to test xrootd SE for analysis
