摘要:
System, computer implemented method and computer program product for preparing and navigating a query tree including a plurality of query nodes and informational nodes. Each query node is associated with a prompt, branching criteria and keywords. A current query node provides a prompt to a user and a user response is received and analyzed to identify branching criteria and keywords from the user response. The method navigates to another node in the query tree in consideration of the branching criteria received in the user response and a comparison between the keywords received in the user response and the keywords associated with the query nodes. The comparison may validate navigation to a destination node corresponding to the branching criteria or the comparison may indicate incorrect navigation of the query tree. Corrective navigation can be implemented in various ways based upon the keywords received in the user response.

Power in a computer system is managed by selectively authorizing requests by devices to operate at an elevated power state. One embodiment provides a computer system having a plurality of hardware devices interchangeably operable at mutually exclusive elevated and lower power states. The lower power states may be selected by default, and the devices independently request to operate at the elevated power state for a specified duration. A power management device, such as a baseboard management controller (BMC) or a chassis management module is configured for receiving and selectively authorizing the requests from the devices to operate at the elevated power state. The power management device subsequently revokes the authorization of the devices to operate at the elevated power state to enforce a system power limit.

Methods, apparatus, and products are disclosed for providing position information to computing equipment installed in racks of a datacenter that includes: projecting, by a projection module, a plurality of optical signals to a plurality of reference points on at least one reflective surface above the racks of the datacenter, each optical signal corresponding to one of the reference points and encoding reference point position information for that corresponding reference point; detecting, by a position detection module mounted on one of the racks, one or more of the optical signals reflected off of the reflective surface; determining, by the position detection module, rack position information in dependence upon the reference point position information; and providing, by the position detection module, the rack position information to a position information consumer that uses the rack position information to identify the position of the rack on which the position detection module is mounted.

Control of LCD backlighting, contrast, and video port selection with BIOS. Calls made from application programs to BIOS result in BIOS read and write operations to a distributed register in video adapters. The use of the register allows BIOS to simultaneously obtain information from multiple displays, as well as simultaneously execute hardware functions such as backlight control. In addition, use of BIOS simplifies programming of hardware related tasks such as backlight control to improve mean time between failure (MTBF) of LCD displays.

An aggregated server blade system includes a plurality of individual server blades and a management module which can be designated as a bootable device. A boot list maintained and executed in each server blade includes a management module entry in its list of bootable devices. In response to the management module entry being selected or otherwise made active as the bootable device for a particular blade, an alternative bootable-devices list maintained on the management module is referenced and the boot process proceeds according to the alternative list.
摘要:
A method and computer program product for controlling energy utilization includes receiving user activities from each of a plurality of users into one or more software application, associating each user activity with a defined workspace having one or more remotely controllable electronic devices, and controlling energy utilization of the one or more electronic devices within each defined workspace according to the user activities associated with the defined workspace. Energy utilization is reduced in a defined workspace during a time period that there is no user activity associated with the workspace. Optionally, the step of receiving user activities may include detecting that a user has logged onto a remote computer that is not located within the defined workspace, or users inputting activities into a software application, such as one or more instances of an electronic calendar.

Managing power domains in a data center including establishing a unique domain identification for each electrical path connecting one or more computing devices to a power source; receiving, by a management module from the computing devices, the unique domain identifications; maintaining, by the management module, a map associating the unique domain identifications with identifications of the computing devices; reporting, by a monitoring module to the management module, status information of a monitored power service module located in a particular power domain; and identifying by the management module an action to take in dependence upon the status information and the map of the unique domain identifications for the computing device.
