Our approach

YESTERDAY TODAY

ACHIEVEMENTS TO DATEWhere we are

11/04/2023 5

Performances we are able to propose

PUE below 1.1, Calculated using meteorological data from 2003,

PUE Effective day one PUE is totally independent of the datacenter load,

Very High Density Up to 30/35 kW IT per rack (12 kW IT / sqm),

Building design to meet maximum Air flow cooling capacity,

11/04/2023 6

Performances we are able to propose

Multi Tiering Architecture for power distribution,Tiering level can be different rack per rack accordingly to real needs?

Solution independent from technology and/or manufacturers,

Significant costs reduction,Investments by 20 % (Based on our first tender won)Running cost (Due to PUE performance and characteristic – effective day one)
