A method for managing the power of a chassis includes receiving a plurality of modular information handling systems into the chassis, receiving a plurality of information handling resources into the chassis, virtualizing access of one of the modular information handling resources to two or more of the plurality of modular information handling systems, the modular information handling systems sharing the modular information handling resource, and, upon initialization of one of the information handling systems, determining power requirements of the shared information handling resource, receiving power requirements from the information handling systems, determining whether the power requirements from the information handling system includes power requirements of the shared information handling resource, subtracting the power requirements of the shared information handling resource from the power requirements of the information handling system to determine resultant power requirements, comparing the resultant power requirements with available power, and allowing operation of the information handling system.

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.

A modular enclosure including first, second, third, and fourth servers, and a chassis management controller. The first, second, and third servers each have reclaimable power. The fourth server is configured to request a specific amount of power needed to complete a power-on request received at the fourth server. The chassis management controller is in communication with each of the first, second, third, and fourth servers. The chassis management controller is configured to reassign all the reclaimable power of the first server and to reassign a portion of the reclaimable power of the second and third servers to the fourth server.

A method may include generating an efficiency curve for each of a plurality of power sources and operating the plurality of power sources based at least on the generated efficiency curve. Generating the efficiency curve for each power source may include coupling a test load to the power source for a period of time, measuring an output power after the period of time, determining a productivity of the power source, determining an efficiency of each power source based at least on the measured output power and the determined productivity, repeating the efficiency determination of the power source for a plurality of different test loads, and generating an efficiency curve from at least the determined efficiencies.
摘要:
A method, system, and software instructions for allocating power in a information handling system are operable to respond to a power profiling request by transitioning a processing resource to a first power consumption state and obtaining and storing a first power consumption value. The first power consumption value is then retrieved and used to allocate power to the first processing resource in response to a power on request. The first power consumption state may be a state in which power consumption approximates a maximum power consumption. The processing resource may be further transitioned to a second power consumption state and a second power consumption value obtained. The second power consumption state may be a reduced performance state. Thereafter, responsive to determining that the system lacks sufficient power budget to fulfill a pending request for power, the processing resource is throttled and power is allocated using the second power consumption value.

An information handling system includes a device, a controller, and a license manager subsystem. The controller is configured to determine whether the device has a license assigned and to extract a unique identification for the device in response to a request for information about the device. The license manager subsystem is configured to send the request for information about the device to the controller, to send the unique identification for the device to a license server as a request for the license for the device, to receive the license from the license server, and to assign the license to the device when the license is received.

In an information handling system, a universal serial bus (USB) key emulation system includes a USB hub operable to communicate with a USB host, a USB bus communicatively coupled with the USB hub, a USB controller communicatively coupled with the USB bus via a set of endpoints, and a USB virtual media module communicatively coupled with the USB controller and operable to communicate data between the USB controller and a plurality of data storage devices as if the plurality of data storage devices are a single USB key.

A method of operating a remote access control unit which comprises first and second units each having an Ethernet port for remotely controlling modules of a server system, comprises the steps of powering up the server system; initializing the first unit into master mode thereby establishing a remote access through the first Ethernet port; assigning and storing a remote access address for the first unit; controlling modules of the server system by the first unit via a communication bus; initializing the redundant second unit into slave mode and disabling a coupling of the modules and the second unit; establishing a communication path between the first and second unit; and monitoring operability of the first unit; wherein upon failure of the first unit, the first unit is decoupled from the modules, the second unit is switched to master mode, thereby establishing a remote access through the second Ethernet port using the previously stored address and coupling the second unit with the modules for control operations.

A computing system and operating method are executable on a target processor and bootstrap loads and run an application program or interface from an alternative medium, for example a CD-ROM medium or via a network link, when an operating system associated with the application program or interface is not installed on the target processor. For example, a computing system includes an executable program code or command entries that load and run a graphical user interface functionality when the operating system associated with the graphical user interface is not installed. The computing system typically includes a processor, a CD-ROM drive coupled to the processor, and a Random-Access Memory (RAM) Drive coupled to the processor. The executable program code or command entries substitute a designator of the RAM-Drive in place of predefined drive designators that are hard-coded into base code of the operating system. The executable program code or command entries disable various functionalities of the operating system that interfere with operating system operations arising from the RAM-Drive. The executable program code or command entries modify a registry in the operating system to permit storage of data on the RAM-Drive and to execute applications from an alternative source such as the CD-ROM drive or via a network link, for example.
