Coordination

• After the first setup and functional tests need to “open” the usability of the lake and focus on three main activities: 
  • eulake and external "standard" storage (Enrico): xrdcp TPC (Third Party Copy), FTS, gridftp, Data deletion
  • File locality (Andrey Zarochentsev): gathered, scattered and hybrid file co-location methods
  • File layouts: striped and full replica layouts: functionality over the WAN/LAN
  • Network performance (Andrey Kirianov): PerfSonar integration

Thanks to AndreyK, AndreyZ and Enrico for volunteering taking leadership on some of the activities. Need one responsible for “File layout”

• Reminder: please do document the setup of your disk/nodes in our Twiki: https://twiki.cern.ch/twiki/bin/view/WLCGDatalakes/WebHome
