  1. Vlbi Storage Manager

  2. System Architecture

  3. Network environment

  4. Vlbi antennas schedule This table is modeled after the present text file worked out in Bonn to coordinate european VLBI observations

  5. Each observation is registered In the antenna table

  6. Each network station management host can be reached and its status monitored…

  7. Network admin can conveniently update the vlbi observations through a FORM

  8. System Architecture

  9. Station environment

  10. VSM Storage Station The “VSMstorage stations" are the structures that manage one or more "storage unit" under the supervision of the technical staff of the organization A storage station can manage one or more well connected antennas • A VSM storage station is made by: • One or more storage units • The VSM Software • The VSM Database of space usage in the storage units • The VSM Database of the local experiments

  11. The VSM System core concept is to manipulate the antennas’ scheduled and present data record on different MySQL databases. Dual implementation for the local admin management: - CLI (Command Line Interface) Bash - WEB-BASED Interface Php

  12. CLI Interaction Command set:

  13. WEB-BASED Interaction

  14. WEB-BASED Interaction A php replica of the bash command set… • In detail: • Storage status • Reservespace • Schedule observations

  15. WEB-BASED Interaction Through Storage status we get the space occupied on the filesystem by experiments on machines

  16. WEB-BASED Interaction Reserve space has done its job and checked if there is enough room for the upcoming observations and now we’re ready to schedule them…

  17. WEB-BASED Interaction The jobs are ready to be scheduled on the machines with the appropriate command at the selected time

  18. WEB-BASED Interaction The jobs are now waiting on the machine in the at queue

  19. A primary PoP of the NREN at the IRA HQ building With Lambda DWDM device

  20. Network for VLBI in Italy

  21. IPERF Transfer tests: Bologna  Metsahövi Metsahövi Bologna

  22. Medicina status Router in Medicina with 2 optical 10 Gbit ports and 2 CX4 ports Bad news Mark 5B+ is under repair, problem with motherboard Good news DBBC + Fila 10G network card arrived, setup in January 10 Gbit network isssues solved, now fully tested and ready
