Most of existing Data Centers have been created using decentralized approach, with sizes, which often do not exceed 180 m² and a dedicated IT team. However, this reality has been transforming due to the fast global increase of data consumption and the need to fulfill this demand at the same speed. Thus, we faced the appearance of the mega Data Centers.
The IT resources have been increasingly more consolidated, once the operational efficiency of the whole data center is under its control – simplify and minimize the failure points, manager the recovery – in addition to more efficient power management by means of low power consumption and heat generation.
Another revolution we are accompanying is the impacting use of the Cloud Computing. The simultaneous increase of data consumption, storage, security and hardware requirements together with the reduction of the world costs of servers and bandwidth is driving an exponential growth either in the use or in the demand for these services.
