Description
The ASTRI (”Astrofisica con Specchi a Tecnologia Replicante Italiana”) and Mini-Array project is
a collaborative international effort led by the Italian National Institute for Astrophysics (INAF)
for developing an array of nine 4m-class dual-mirror imaging atmospheric Cherenkov telescopes.
These telescopes will be sensitive to gamma-ray radiation at energies above 1 TeV. The Mini-Array
is under construction at the Teide Observatory (Canary Islands). The ASTRI Mini-Array Informa-
tion and Communication Technology (ICT) is distributed between the “on-site”(Teide) segment,
to support the development, installation and on-site operations of the ASTRI Mini-Array, and the
“off-site “(Rome, Italy) segment for data archiving and user support activities (see the companion
contribution at this meeting).
In this contribution it is described the design of the “on-site” ICT infrastructure, which includes
various subsystems that can support various software components and how are foreseen all related
implementations. The design of the virtual system for controlling telescopes, the data acquisition
and data storage as well as the computing system are described too. All these components are
connected together so a particular attention to the network topology is also given in order to
guarantee nominal runtime together with the required data transfer throughtput to the off-site
long term archive facility.
Finally, it is introduced and described the mini-ICT , which is a reduced version of main on-site ICT
infrastructure, currently installed in the ASTRI-MiniArray site to ensure the preliminary operation
and validation of the subsystems and technologies adopted for the first three telescopes installed,
before the final ICT infrastructure is in production.
Finally the m-ICT has proved to be not only a workaround to compensate for the lack of the final
ICT, but revealed to be fundamental in validation and testing of subsystems like the optical fiber
network and Internet connection as well as the SCADA software integration.
