MIX offers to its Members and Carriers leading edge technological infrastructure, the Data Center has the ISO-27001 certification and a great level of reliability and redundancy of power supply and cooling system. Different solutions, managing procedures and support are provided in order to ensure the maximum neutrality of the Data Center, according to the role and Mission of Milan Internet Exchange. From the electrical point of view, it is organized in four different sub-sections: two for each physical macro area, divided in turn in two different sub-areas. The power supply lines of the sub-area are called “Line A” and “Line B” and are deployed from two different path connected to the local distribution network. The UPS is completely redundant in each of its components: each main power distribution board has its own 250 kVA UPS. The two UPS of each macro section are then connected to two 250 KVA distinct and identical generators. This continuity of power supply applies both to the 230V AC powered devices as well as to the -48V DC powered ones.
