Patent number: 9436257Abstract: A system includes power supply units (PSUs) to supply power to components. For each PSU, a power conversion efficiency profile is determined. A maximum amount of power consumed during operation of the components is determined. A minimum number of PSUs capable of providing the maximum amount of power is determined. A first amount of power consumed at inputs of the minimum number of PSUs is calculated based on the maximum amount of power and based on the determined power conversion efficiency profile of each of the PSUs. A first number of PSUs to engage is determined, the first number greater than the minimum number of PSUs, wherein a total amount of power consumed at inputs of the first number of PSUs during operation of the system is less than the first amount of power, the determining based on the power conversion efficiency profile of each PSU.Type: GrantFiled: December 18, 2014Date of Patent: September 6, 2016Assignee: DELL PRODUCTS, LPInventors: Ashish Munjal, Jaydev Reddy, Michael J.

Patent number: 8918656Abstract: An information handling system includes a plurality of power supply units (PSUs) to supply power to one or more system components. For each PSU of the plurality of PSUs, a power conversion efficiency profile for the PSU is determined using a power management control module of the information handling system. The power conversion efficiency profile represents a power conversion efficiency of the PSU for each of one or more power outputs capable of being supplied by the PSU. The power management control module determines a total amount of power to be supplied to a load of the information handling system, and engages a select number of PSUs to provide the total amount of power based on the total amount of power and the power conversion efficiency profiles of the PSUs.Type: GrantFiled: June 30, 2009Date of Patent: December 23, 2014Assignee: Dell Products, LPInventors: Ashish Munjal, Jaydev Reddy, Michael J.

Patent number: 8806256Abstract: A power supply unit of an information handling system determines that a power consumption module of the information handling system is available. If the power consumption module is available, the power supply unit measures input power of the power supply unit and provides a representation of the input power to the power consumption module in response to receiving a power measurement request from the power consumption module. If the power supply unit determines that the power consumption module is not available, the power supply unit measures input power of the power supply unit and stores a representation of the input power at the power supply unit independent of a power measurement request from the power consumption module.Type: GrantFiled: May 28, 2013Date of Patent: August 12, 2014Assignee: Dell Products, LPInventors: Ashish Munjal, Alan Brumley, Jaydev Reddy

Patent number: 8499178Abstract: An information handling system having plural processing modules, such as an information handling system blade chassis having plural information handling system blades, allocates power by determining an actual load sharing power loss associated with plural power supplies and applying the actual load sharing power loss to determine how much power to allocate to the information handling system modules. A chassis manager determines actual load sharing power loss by retrieving power information from plural power supplies. The actual load sharing power loss replaces a worst-case load sharing power loss assumed value to increase the amount power available for allocation to the information handling system modules.Type: GrantFiled: January 30, 2012Date of Patent: July 30, 2013Assignee: Dell Products L.P.Inventors: Timothy M. Lambert, Jaydev Reddy, Ashish Munjal

Patent number: 8156358Abstract: Infrastructure power resources of a chassis information handling system are made available to run chassis information handling system modules when infrastructure devices are not using the power resources. For example, cooling fans that cool information handling system modules supported by an information handling system chassis run at variable speeds having variable power consumption. A power reserve maintained to run the cooling fans at full speed if needed is made available to information handling system modules when under power management by a chassis manager.Type: GrantFiled: February 19, 2009Date of Patent: April 10, 2012Assignee: Dell Products L.P.Inventors: Alan Brumley, Jaydev Reddy, Ashish Munjal, Arun Munhalyan

Patent number: 7383454Abstract: A blade information handling system server prevents excess power demand from blade information handling systems by inventorying the power consumption of each blade information handling system before startup. Another power consumption inventory performed after startup ensures an accurate power consumption inventory for making subsequent startup decision. The baseboard management controller performs the first power consumption inventory with the processing components of the blade information handling system in an off state. The power inventory is communicated to the chassis management controller to obtain authorization to startup based on the power available at the chassis. The second power inventory is performed with the processing components in an on state and forwarded to the chassis management controller for use in subsequent determinations of power available at the chassis.Type: GrantFiled: April 18, 2006Date of Patent: June 3, 2008Assignee: Dell Products L.P.Inventors: John S.
