System and method for power management in a computer system having multiple power grids
First Claim
1. A system for power management in a computer system having at least one power grid, said computer system operating to execute at least one instance of an operating system (OS), comprising:
- at least one uninterrupted power supply (UPS) operating to supply power to a portion of said at least one power grid, wherein said at least one UPS is operable to send a loss of power notification;
at least one alternative source of power for supplying power to said at least one power grid; and
a service structure executable on said computer system, said service structure for monitoring said at least one UPS and said at least one alternative source of power, wherein said service structure is operable, responsive to receiving said loss of power notification from said at least one UPS, to continue to maintain power supply of said computer system from said at least one alternative source of power upon determining that said at least one alternative source of power is operational.

Abstract
A system and method for power management in a computer system having multiple power grids is disclosed. The system includes a service structure operable in conjunction with an operating system (OS) instance executed on the computer system. At least one uninterrupted power supply (UPS) and at least one alternative source of power provide power to the multiple power grids. Where an UPS sends a loss of power notification to the service structure, the service structure is operable to maintain power supply to the grids from an available alternative source of power.

12. A method for power management in a computer system having at least one power grid, comprising:
-
receiving a loss of power notification from an uninterrupted power supply (UPS) associated with a portion of said at least one power grid; querying an alternative source of power associated with said at least one power grid for power, availability; continuing to supply power to said computer system from said alternative source of power upon determining that said alternative source of power is available; and sending a loss of power message to an operating system (OS) instance executing on said computer system if no power is available from said alternative source of power. - View Dependent Claims (13, 14, 15, 16)

17. A system for power management in a computer system having multiple power grids, comprising:
-
means for receiving a loss of power notification from an uninterrupted power supply (UPS) associated with a portion of said multiple power grids; means for querying at least one alternative source of power associated with said multiple power grids for power availability; means for continuing to supply power to said computer system from at least one available alternative source of power; and means for sending a loss of power message to an operating system (OS) instance executing on said computer system if no power is available from said at least one alternative source of power. - View Dependent Claims (18, 19, 20, 21)

22. A system for power management in a computer system having at least one power grid, comprising:
-
at least one uninterrupted power supply (UPS) operating to supply power to a portion of said at least one power grid, wherein said at least one UPS is operable to send a loss of power notification; at least one alternative source of power for supplying power to said at least one power grid; and a service structure executable on said computer system, said computer system operating with a first instance and a second instance of an operating system (OS), said service structure for monitoring said at least one UPS and said at least one alternative source of power, wherein said service structure is operable, responsive to receiving said loss of power notification from said at least one UPS, to continue to maintain power supply of said computer system from said at least one alternative source of power upon determining that said at least one alternative source of power is operational, and further wherein said service structure is operable to send a loss of power message to said second instance of OS via a slave service structure associated therewith upon determining that no alternative source of power is operational. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29)
