Data Sharing & Preservation


 IA2 Archives Center, in addition to the activities related to the management of the main INAF archives from ground-based telescopes, also provides the INAF community with medium and long-term storage support.

Each request (space increases, account activation or simple info) must be made by e-mail: Questo indirizzo email è protetto dagli spambots. È necessario abilitare JavaScript per vederlo.t

About Storage , IA2 provides Middle and Long Term Storage in the following ways:

  • Owncloud ( Collaborative cloud storage available for all INAF employees / associates. (Each employee can connect with the INAF / IDEM account, and has 10G available by default. Space increases may be requested.

  • Storage space dedicated to users / projects. Access is done via ssh for both Middle Term and Long term storage.Activation request must be made as indicated above.An interface for the implementation of VOSpace is being developed in which it will be possible to deposit and retrieve data directly on both Middle and Long Term Storage.


The IA2 infrastructure currently have (for all projetcs)
1.5 PB of disk space on 3 separate stacks
2.5 PB of tape space (expandable to 8PB)




Please remember that:

  • Storage: it is a place where data is simply placed to allow their subsequent use. The organization is given by the user who owns it, and where possible sharing with other users is possible
  • Archive: it is the place where the data, in addition to being located, are also organized through the OAIS standard, and therefore searchable through dedicated interfaces.

It should also be noted that when we talk about Storage we are essentially talking about:
  • Fast storage: Reduced space and directly connected to the computing system
  • "Middle term" storage: Storage on high-capacity rotary HDs with reduced I / O speeds
  • "Long term" storage: Storage in the Tape Library whose access is asynchronous
