Patent ID: 8879257

Claim:
A method of providing an apparatus for facilitating power and cooling of at least one electronics rack, the method comprising: providing a frame; associating at least one bulk power assembly with the frame, the at least one bulk power assembly being configured to provide power to the at least one electronics rack, wherein the frame with the associated at least one bulk power assembly are distinct from the at least one electronics rack; associating at least one heat exchange assembly with the frame, the at least one heat exchange assembly being configured to cool system coolant provided to the at least one electronics rack, wherein heat is transferred by the at least one heat exchange assembly from the system coolant to a facility coolant, and wherein the frame with the associated at least one bulk power assembly and associated at least one heat exchange assembly provides both power and cooling to the at least one electronics rack; and providing at least one facility coolant sub-loop and at least one facility coolant-cooled cold plate, the at least one facility coolant sub-loop being coupled in fluid communication with the at least one facility coolant-cooled cold plate, and the at least one facility coolant-cooled plate is disposed in thermally conductive contact with at least one heat-generating component of the at least one bulk power assembly, the at least one facility coolant sub-loop and at the least one facility coolant-cooled cold plate facilitating transfer of heat from the at least one heat-generating component of the at least one bulk power assembly directly to the facility coolant.
