In one example, a heat pipe is configured to absorb and transfer heat away from ambient air of a data center to cool the ambient air circulating in the data center to cool devices of the data center, and a fluid interface is thermally coupled to the heat pipe and configured to cool the heat pipe via a coolant fluid circulating in the data center. In another example, a heat pipe configured to release transferred heat to air, and a fluid interface is thermally coupled to the heat pipe and configured to exchange heat to the heat pipe to cool a coolant fluid circulating in a data center to cool devices of the data center.

Data center cooling using a heat pipe

A control logic firmware is received at a power supply unit. The firmware specifies a configuration selected to place a magnitude of an impedance of the power supply unit above a magnitude of an impedance of a network data center power system. The control logic firmware is executed using a power factor correction circuit of the power supply unit including by setting a voltage loop phase margin of the power factor correction circuit to maintain the magnitude of the impedance of the power supply unit above the magnitude of the impedance of the network data center power system.

Electrical system stability

A data-center-module deployment apparatus may include a gantry robot adapted to move a sliding element parallel to a face of an information technology rack, where the face of the information technology rack exposes information technology device modules stored by the information technology rack. The apparatus may also include at least one track that is coupled to the sliding element and that extends away from the sliding element and toward the face of the information technology rack. In addition to the track(s), the apparatus may include an engaging element that is adapted to move along the track(s) and to engage with one or more of the information technology device modules stored by the information technology rack, such that the engaging element is adapted to insert into the information technology rack and remove from the information technology rack one or more of the plurality of information technology device modules.

Apparatus, system, and method for deploying data center modules

To avoid the need to operate in-chassis fans to cool rack-mounted servers in a data center, the data center is arranged into a hot aisle and a cold aisle. The cold aisle is adjacent to a first side of the rack mounted servers and receives cold air from a cold air supply unit. The hot aisle is adjacent to a second side of the rack-mounted servers and has a lower pressure than the cold aisle. Because of the pressure difference between the cold aisle and the hot aisle, cold air flows through the rack-mounted servers, cooling electronic equipment therein, into the hot aisle. Control systems are used to obtain sufficient cooling.

Cooling servers in a data center using fans external to servers

The need for backup diesel generators in a data center is obviated by using fuel cells to convert a fuel to electrical energy, which provide backup power to equipment in a data center, which may include the servers in the data center and other important systems that normally use utility power. When the utility power fails, the equipment switches to backup power that is provided by fuel cells supplied with fuel (such as natural gas), possibly using a source of temporary power (e.g., a UPS or direct tie-in of batteries) while the fuel cells come online. The fuel may also be used to power a turbine or generator, coupled to a chiller for providing a cooled liquid to a cooling system.

Data center using fuel cells in place of diesel generators for backup power

A data center is electrically coupled to a power grid at two separate access points, which may be located within geographic proximity to each other. Each access point is located between two power generation systems. The access points have one or more power generation systems located between them, allowing the data center to be coupled to three or more power generation systems simultaneously and have access to power in the event of multiple power generation system failure. The data center may comprise two separate data center power inputs, which may each be connected to a separate power grid access point. The power grid may provide a high voltage level to the data center, and the data center may comprise transformers which step the voltage down to a lower voltage level. The data center may comprise one such transformer coupled to each of the two data center power inputs. The outputs of such transformers may be coupled together.

Powering a data center using multiple connections from a utility grid

The need for an uninterrupted power supply (UPS) in a data center is obviated by tying a DC voltage from a backup power source directly to the motherboards of multiple servers in the data center. AC power received from a power utility service is converted into a lower voltage by a site transformer and then provided to one or more power distribution units at a site. The power distribution units supply power to a plurality of servers, which include power supplies that convert the AC electrical power to DC electrical power for use by the servers' motherboards. In the event of a failure of power from the utility service, the backup power source provides DC electrical power to the motherboards, e.g., for sufficient time to start up a generator to provide power in place of the utility service.
