The data centers in Arezzo (IT1) and Milan PSP (IT3) respect the highest levels of resilience set by ANSI/TIA-942 Rating 4 (formerly Tier 4)
Rating 4 (formerly Tier 4) is the highest level outlined by ANSI/TIA-942 and classifies a data center as an infrastructure capable of avoiding interruption of services even in the event of serious failures, thanks to the installations' high levels of redundancy.
A Rating 4 (formerly Tier 4) data center has redundant components constantly in operation, as well as multiple supply routes and hardware cooling systems.
The data center is equipped to withstand a failure in any part of the installation without causing downtime and is protected against physical events, including natural catastrophes (e.g. fire, flood, earthquake, etc.).
A data center can be compliant with Rating 4 standard (formerly Tier 4) for its design also in the development phase (Design Validation). Once in operation, the data center will be subjected to an inspection by ANSI/TIA to verify the Rating 4 (formerly Tier 4) construction, As Built Validation.
ANSI/TIA-942 is one of the main standards of reference worldwide for the validation of the quality of the infrastructure and the guarantee of service continuity in a data center. TIA-942 is the only standard of reference and classification adopted by AGID (Agency for Digital Italy) for the classification of the data centers of Italy's Public Administration.
