Abstract: Method, computer program products and systems for conserving energy in data processing center, wherein a plurality of services are offered to a plurality of subscribed service consumers in a dynamic fashion, allowing a created service instance to be re-assigned from one to another server of the resources. Control parameters comprising power consumption and temperature of a group of resources are monitored. A workload may be assigned properties such as “hot” and “cold.” which are then assessed. A hot workload may be relocated to a cold spot, and if necessary, a cold workload may be relocated to a location which was de-loaded from a workload, that is, a hot spot, which is then considered to cool down due to addition of less workload in form of the cold workload. Thus, the energy required to cool the data center may be minimized.

Abstract: A system for identifying a subset of sensors to sample to reduce the frequency of sensor access. The system determines rise times and records values for the sensors in the system. A time criticality of the sensors is determined based on the rise times. The system processes the sensors by first creating sensor subsets based on one or more constraints on the sensors. The system monitors the values of the sensors in a sensor subset and flags a sensor when it makes a determination that, prior to a next scheduled sampling of the sensor subset, the value of a sensor in the monitored sensor subset will exceed a threshold constraint. The system moves those flagged sensors to a second sensor subset which complies with the sensor's constraints.

Abstract: A method and corresponding apparatus is provided for determining the location of a configuration server being connected to a totally symmetric network infrastructure that does not exhibit any symmetry breakers on network level. The configuration server reaches a decision to determine its network-wide unique configuration in order to be able to serve controllers. This decision depends on the plug position of the configuration server under consideration and the assumption of plugging rules governing a “good” network infrastructure. The controllers periodically send network packets that will be marked if they traverse specific connection elements in the network. The origin and the path of a network packet can be determined. The decision making is based on a majority function based on the packets received by the configuration server. If a decision cannot be made, then errors in the cabling structure can be detected.

Abstract: A method, apparatus and computer instructions are provided for controlling communications between controller devices over an I2C bus hardware interface and a separate communication line, such as a GPIO line. With thermal/power management firmware installed on a system controller device, communications between the system controller device and a real time embedded controller device are sent using a predefined protocol whereby the system controller generates commands to the embedded controller by first performing an I2C write with a command packet, followed immediately thereafter by an I2C read to get the return packet. The embedded controller processes the command and returns the response to the I2C read. In addition, the embedded controller is able to make the system controller aware that it has a communication request by interrupting the system controller by asserting the separate communication line, in response to which the system controller issues a status request command to the embedded controller.

Abstract: A system is provided for unified management of power, performance, and thermals in computer systems. This system incorporates elements to effectively address all aspects of managing computing systems in an integrated manner, instead of independently. The system employs an infrastructure for real-time measurements feedback, an infrastructure for regulating system activity, component operating levels, and environmental control, a dedicated control structure for guaranteed response/preemptive action, and interaction and integration components. The system provides interfaces for user-level interaction. The system also employs methods to address power/thermal concerns at multiple timescales. In addition, the system improves efficiency by adopting an integrated approach, rather than treating different aspects of the power/thermal problem as individual issues to be addressed in a piecemeal fashion.

Abstract: A system and method of parameter measurement for a distributed computer system, the method including selecting a master unit; selecting slave units operably connected to the master unit on a bus, the slave units having a slave clock; determining slave unit latencies between the master unit and the slave units; generating slave unit synchronizing signals for the slave units, the slave unit synchronizing signals being adjusted for the slave unit latencies; synchronizing the slave clocks in response to the slave unit synchronizing signals; and measuring an operating parameter at the slave units at a synchronously determined time.

Abstract: A method, apparatus, and computer-usable medium for predicting capacity on a data processing system. According to a preferred embodiment of the present invention, a capacity manager estimates an incremental power value utilize for activating and maintaining an additional processor in the data processing system. The capacity manager calculates a power headroom value. In response to calculating the power headroom value, the capacity manager determines whether an adjustment power headroom value is required. The capacity manager calculates a projected capacity value added by the additional processor to the data processing system.

Abstract: A system and method for an initial boot of a system before adding or removing drawers to a system without requiring an n-level cable. Standby power is applied after all cables have been connected to the system. All available expansion ports for an SMP cable are searched. A unique ID is sent over and received by all plugged SMP cables. A list of each controller and its connected controllers is created, and a master controller is assigned. A plugging table of each controller is sent to the master controller. The master controller compares all received plugging tables to plugging rules. Errors are reported in cable plugging errors and system configuration is reported to platform management service.
