VO Auger data distribution (TB)

(VO auger support has ended in 2015)

Networks Services People ∙ ∙ www.geant.org

• manual (lcg-cp)• FTS3 (FZK)• recently very low• < 10 TB in total during the last 2 month

• biggest traffic: from active sites to CC IN2P3 • “consolidation” of results

• total data volume registered in LFC: 821 TB• slow increase in total data volume• estimated total 1 PB at the end of 2016

Data transfers
