- telecommunicational infrastructure that connects the elements of data-center, as well as data transmission between data-center and users;
- engineering infrastructure that provides normal functionality of main systems of data-center.
Engineering infrastructure includes conditioning systems for retaining the temperature and humidity on the needed level, the power supply without interruptions for the autonomous work of data-center in case power systems fail, security and fire prevention systems, remote IP-control system, the power management and access systems.
