摘要:
A method for managing the power consumption of an information handling system including a multi-lane serial link having a lane setting that identifies the number of active lanes in the multi-lane serial link. The method may include determining a number of lanes required for the multi-lane serial link based on one or more I/O devices connected to the information handling system, triggering a reduction of the lane setting of the multi-lane serial link if the lane setting of the multi-lane serial link is greater than the determined number of lanes required, and automatically reducing power to the multi-lane serial link in response to the reduction of the lane setting.

Methods and systems are disclosed for power usage level management of blades installed in blade servers. When a new blade added is to a blade server, possible power usage levels for the new blade are assessed to determine possible effects on the total power usage level of the chassis. By assessing the different power usage levels, the chassis controller can then make intelligent decisions as to the power usage levels at which new blades will be allowed to operate while still keeping within chassis power supply capabilities. Blade power usage levels can be based upon a variety of considerations, including processor performance modes and blade configuration options.

摘要:
Information handling system power consumption across plural information handling systems, such as a rack of servers, is managed to restrict operations of the information handling systems to within a maximum total power consumption. Power consumption is restricted if necessary to maintain a level below the maximum by selectively operating one or more information handling systems in a reduced power mode or by disapproving operation of one or more information handling systems. Monitoring of power consumption and configuration of reduced power consumption modes is managed by a management controller associated with each information handling system.

A system and method for performing a VM migration which manages a cluster of machines in a pool for live migration to the same feature set or behavior. In certain embodiments, machines within the pool can be configured to emulate a certain feature set to enable a VM migration amongst the similar pools. The emulation can be by either masking reporting of a feature set or enabling/disabling a feature set. The handling of emulation registers within the hardware occurs at a firmware level rather than an operating system or hypervisor level.

A remote access module associated with a BIOS of an information handling system having a UHCI-based USB controller allows selection of legacy USB control with a local keyboard or access by a remote keyboard through a remote access bus master adapter. Input from an inactive local or remote keyboard results in automated enabling of the inactive keyboard and disabling of the active keyboard. In one embodiment, remote access to a keyboard port during legacy USB control saves the data associated with the remote access to a memory location accessible to the BIOS and invokes the BIOS to obtain the data. In another embodiment, a legacy USB control option is offered by a display to a user associated with a local keyboard and legacy USB control disabled if the user fails to select local access in a predetermined time period.
摘要:
An information handling system includes a set of power and performance profiles. Based on which of the profiles has been selected, the information handling system selects a thread scheduling table for provision to an operating system. The thread scheduling table determines the sequence of processor cores at which program threads are scheduled for execution. In a power-savings mode, the corresponding thread scheduling table provides for threads to be concentrated at subset of available processor cores, increasing the frequency with which the information handling system can place unused processors in a reduced power state.

In accordance with the present disclosure, a system and method for multilayered authentication of trusted platform updates is described. The method may include storing first cryptographic data in a personality module of an information handling system, with the first cryptographic data corresponding to a verified firmware component. A second cryptographic data may also be determined, with the second cryptographic data corresponding to an unverified firmware component. The unverified firmware component may be stored in a memory element of the information handling system, and the second cryptographic data may be determined using a processor of the information handling system. The method may further include determining if the first cryptographic data matches the second cryptographic data and updating firmware in the information handling system with the unverified firmware component if the first cryptographic data matches the second cryptographic data, and the unverified firmware component includes a digital signature of a manufacturer.
