22.  FOREST uses a closed loop refrigerant-based cooling
system
 Chilled water is used to cool the refrigerant
 The water is localized to one end of the container
which reduces exposure in the event of water
leakage

26. DC Rectifier Design and Benefit
 X7500
 Single phase rectifier 200 - 305vAC to -48vDC
 8kW per rectifier
 Three Hot Swap rectifiers per shelf
 93% efficient (new design to 96%)
 Up to two shelves per Carriage or Rack
 Tolerates 1 cycle of dropout at 100% of load
 Drives container PF to near unity
The AC power comes into the supplies and that power is isolated
from the DC bus that feeds the servers. Thus all server load is
applied against the common DC bus so wherever the load is coming
from it sees the same bus. In other systems, the AC power comes
directly to the servers, so the way the servers spread the load leads
to the imbalance across the AC phases.
