One of biggest problems of data processing centers is the energy consumption. This is specially important in a supercomputing center, because the consumption when the processors works at 100 % is very high, as is obvious in a supercomputing center there are a lot of them. So the great challenge of modern supercomputing centers is to face the high density requiered.
From the electrical point of view, it involves having within each rack, enough supply for the requiered density (in the case of the FCSCL, until 45 kW/rack). And morover, due to the special needs of customers and users of FCSCL, the electrical system must be ready for working 24*7*365 as we have explained. Thus, following the normative TIA-942, there are two independet power branches that supply each rack. The equipments, which have at least N +1 power supply are connected simultaneously to both branches (each rack has at least two terminal blocks, each plugged into a branch. There are racks with six Exists wardroves with until six power strips). The terminal blocks are of different densities (from 16A single-phase to 96A three-phase), and combinations of different configurations of C13 and C19 connectors. In any case, all the power-strips have control processor and network interface being monitored.
Each branch of power is supported by a system of supply interrupted (UPS) APC Symmetra PX of 160kVA. These systems are modular in turn, both in power and in capacity. The loss of a module of 16 kVA module reduces the total power delivered by the UPS but does not prevent its work. The autonomy with the load of FCSCL is 25 minutes.
For power failures of longer duration, the FCSCL has an emergency diesel generator of 630 kVA, so that within two minutes from the interruption, the generator is feeding the UPS systems.
