Future development for data transfer
We discuss (CNAF) how to simplify the data transfers
using the tools available on the market.
We identify a solution which should be able to avoid to
run of a linux virtual machine on the DAQ system.
• Globus connect within EU project or Bit torrent sync
– They require just a client running on windows
– Transfers and monitoring are managed via a web interface
– We don’t propose this as the production setup for the pilot
run but it would be useful to test it in the next month in 12 schools.

Filesystem at CNAF
We are designing the final structure of the filesystem were data will be stored
A possible solution:
/filesystem/
/filesystem/GROS-01
/filesystem/ALTA-01
/filesystem/... a directory per school
/filesystem/test
/filesystem/reco/GROS-01
/filesystem/reco/ALTA-01
/filesystem/reco/... a directory per school
/filesystem/user1
/filesystem/user2
/filesystem/user3
/filesystem/... a directory per user

Authentication at CNAF
-
we received so far 2/3 requests (Garbini, Coccetti, Gnesi?).
- in future authentication at CNAF will be mandatory to access the data stored at
CNAF
- The machine to log in is: bastion.cnaf.infn.it (which is the only machine open to
external accesses) and from there you will access all the EEE resources
- the policy to copy files from CNAF to your local machine has to be defined (we
didn't discuss it yet)
-
Per ottenere un account al Tier1 bisogna seguire questa procedura:
https://www.cnaf.infn.it/en/node/315
Verrà fornito login appartenente al gruppo "EEE", che può accedere
all’infrastruttura per la ricostruzione ed analisi dei dati
Specificare come "reason": Accesso alle VM di Cloud@CNAF per il progetto EEE
Specificare come contact person: Cristina Vistoli
