A fluid-cooled computer system includes a plurality of heat-generating components and a cooling system configured for supplying a cooling fluid at a controlled cooling fluid flow rate to cool the heat-generating components. A temperature-based cooling control circuit includes a temperature sensor configured for sensing a temperature of the heat-generating components and control logic for increasing a cooling fluid flow rate in response to the temperature exceeding a temperature threshold. A power-based cooling control circuit is configured for identifying and quantifying an increasing power consumption trend over a target time interval and, during a period that the temperature of the electronic device does not exceed the temperature threshold, increasing a cooling fluid flow rate to the electronic device in response to the magnitude of the increasing power consumption trend exceeding a power threshold. In one option, the fluid-cooled computer system is a server and the heat-generating components include a processor.

Fluid-cooled computer system with proactive cooling control using power consumption trend analysis

A computer-implemented method comprises accessing historical operating data for a unit of information technology equipment, wherein the historical operating data includes power consumption, fan speed, inlet air temperature, workload, and any processor throttling events at various points in time. The method further comprises receiving user input selecting a fan speed, and using the historical operating data to determine a performance impact that is expected from operating the unit at the selected fan speed, where the power consumption is a proxy for performance. The estimated performance impact of the selected fan speed and one or more alternative fan speeds is then displayed.

Optimization of system acoustic signature and cooling capacity with intelligent user controls

Techniques are disclosed for managing inventory data for components of a server system. In one embodiment, a global management controller is provided, that is operatively connected to a plurality of local management controllers. Each local management controller is configured to manage a subset of the components of the server system. Each local management controller is also configured to generate, for each component, a checksum based on vital product data (VPD) of the component. Each local management controller is also configured to compute a composite checksum based on the checksums generated for the components in the subset. The global management controller is configured to maintain a global view of the VPD in the computer system, based on the checksums and/or composite checksums.

Managing inventory data for components of a server system

A method, system and computer program product for managing and deploying physical and virtual environments across multiple hardware platforms. A single unit, referred to herein as a cloud construction block, contains both the hardware and software components used to build a cloud computing environment. By having such a single unit contain both the hardware and software components needed to build a cloud computing environment, the user no longer needs to purchase and integrate different hardware and software components. Furthermore, the cloud construction block contains modular pieces of hardware, such as compute hardware, memory hardware, storage hardware and network hardware, that are integrated with management software configured to manage both the hardware and the cloud computing environment in a seamlessly integrated package. Since there is a single management system, the management software allows the user to manage the modular pieces of hardware via a single user interface.

Unified cloud computing infrastructure to manage and deploy physical and virtual environments

A mechanism is provided for dynamically changing power caps for a set of powered elements. Current being consumed by the set of powered elements P on a branch circuit is measured and available current on the branch circuit is determined. A new total power cap for a current time period t is identified based on a current total power cap and the measured current. A difference in total power caps (&#x394;TPC) is determined and, for each powered element p in the set of powered elements P at the current time period, a new power cap PC (p,t) is determined based on the previous power cap PC(p,t&#x2212;1) and the difference of the total power caps to the set of powered elements P. A power cap of each powered element p is then dynamically set to the new power cap PC (p,t).

Branch circuit power measurement and dynamic power distribution

Methods, computers, and products for managing power consumption of a computer, the computer including a computer processor and managing power consumption of a computer includes: dynamically during operation of the computer, setting, by an in-band power manager in dependence upon performance metrics of the computer processor, a current performance state ('p-state') of the computer processor; and providing, by the in-band power manager to an out-of-band power manager, the current p-state of the computer processor.

A method for dynamic power and performance calibration of a data processing system is provided in the illustrative embodiments. A synthesized program loaded in the data processing system is executed responsive to detecting an event in the data processing system. The synthesized program is configured to generate a set of data that is indicative of the data processing system's power-performance characteristics under varying conditions of operation. Using the set of data, a determination is made of a performance limit on an operation of the data processing system under present operating conditions of the data processing system. A parameter of the data processing system is calibrated to operate the data processing system within the performance limit.

One embodiment provides a method of managing power in a computer system. A device of the computer system is operated at a selected power-state. The power consumption of the computer system is monitored. If the power consumption of the computer system is approaching or has exceeded a power cap selected for the computer system, then a request to reduce the power-state for the device is generated in response. The operating system is used to service the request to reduce the power-state according to the priority of the request. The reduced power state is forced out-of-band following the request to reduce the power-state if the request is not immediately serviceable by the operating system. Different approaches can be taken to force the reduced power state, using, for example, system management mode or a platform environment control interface.

An apparatus, system, and method are disclosed for distributing configuration parameters. The present invention includes one or more storage devices configured to store data, a first DHCP server configured to process DHCP messages and redirect communications regarding configuration parameters for the storage devices to a second DHCP server, and a configuration datastore configured to store configuration parameters for the storage devices. The second DHCP server may be configured to process DHCP messages and retrieve configuration parameters for the storage devices from the configuration datastore. In certain embodiments, each storage initiator communicates with the DHCP servers, receives the configuration parameters such as iSCSI parameters, and provides the configuration parameters to one or more storage devices.
