摘要:
In accordance with the present disclosure, a system and method for performing a system memory save in tiered or cached storage during transition to a decreased power state is disclosed. As disclosed herein, the system incorporating aspects of the present invention may include a flash or other nonvolatile memory such as a solid-state drive, volatile memory, and at least one alternate storage media. Upon transition to a decreased power state, at least some of the data in the solid-state drive, for example, may be transferred to the at least one alternate storage media. After the SSD data is transferred, data stored in volatile system memory, such as a system context, may be transferred to the SSD memory. With the system context saved in SSD memory, power to the volatile system memory may be turned off.

In accordance with the present disclosure, a system and method for creating and dynamically maintaining power inventories of an information handling system is presented. A system for creating and dynamically maintaining power inventories of an information handling system may include a memory and a processor. The processor may be operable to generate power inventories for the information handling system and save the power inventories in the memory. Each of the power inventories may correspond to one of the power states of the information handling system. The processor may also be operable to dynamically update each of the saved power inventories in response to changes in the information handling system.

A method is provided for managing errors in a virtualized information handling system that includes an error detection system and a hypervisor allowing multiple virtual machines to run on the information handling system. The hypervisor may assign at least one memory region to each of multiple virtual machines. The error detection system may detect an error, determine a physical memory address associated with the error, and report that address to the hypervisor. Additionally, the hypervisor may determine whether the memory region assigned to each virtual machine includes the physical memory address associated with the error. The hypervisor may shut down each virtual machine for which a memory region assigned to that virtual machine includes the physical memory address associated with the error, and not shut down each virtual machine for which the memory regions assigned to that virtual machine do not include the physical memory address associated with the error.

A virtualization system includes an information handling system with a power detector that detects a power level of the information handling system and another power detector that detects another power level of the information handling system, a power status module, and a virtual machine manager that starts workloads on the information handling system. The power status module receives the power levels and sends the power levels to the virtual machine manager. The virtual machine manager apportions a first portion of the first power level to the first workload, apportions a second portion of the first power level to the second workload, apportions a first portion of the second power level to the first workload, and apportions a second portion of the second power level to the second workload.

Methods and systems for binding a removable trusted platform module (TPM) subsystem module to an information handling system to provide a core root of trust for the information handling system without requiring soldering down or other hard and permanent (non-removable) attachment of a TPM device to the information handling system planar (e.g., motherboard). The removable TPM subsystem module may be a plug-in module that may be removed from the information handling system planar (e.g., motherboard), while at the same time maintaining the transitive chain of trust, and being capable of remotely attesting its trusted state. An information handling system platform may be provided that has the capability and flexibility of supporting multiple TPMs on the same system planar.

A method for managing a redundant memory architecture for an information handling system (IHS) may include providing redundant memory for a portion of system memory wherein the redundant memory is configured to mirror data stored in the portion of system memory. The method may further include reporting a parameter associated with the portion of system memory to an operating system of the IHS and executing a program from the portion of system memory.

A credential caching system includes receiving a set of authentication credentials, storing the set of authentication credentials in a credential cache memory, wherein the credential cache memory is coupled with a management controller, and supplying the set of authentication credentials for automatic authentication during a reset or reboot. In the event of a security breach, the credential caching system clears the set of authentication credentials from the credential cache memory so that the set of authentication credentials may no longer be used for a reset or reboot.
摘要:
A method for provisioning systems within a solution which includes mapping a physical identifier of a component within a system to a logical identifier of the component within a system and mapping the logical identifier of the component within a system to an implementation identifier of the component within the system. The mapping conforms to a predetermined user identifiable naming convention.

A system and method for interpreting sensor data utilizing virtual sensors includes a plurality of physical sensors having a sensor number, a virtual sensor repository including a plurality of virtual sensors and an event log, a management controller, and one or more agents and allows for a central repository for a plurality of sensor values and a consistent and uniform view of system health. The management controller associates each of the physical sensors with one or more of the virtual sensors utilizing the sensor numbers. The management controller further stores within each of the associated virtual sensors the sensor value from the physical sensor associated with the associated virtual sensor. The one or more agents request and receive the sensor value for a desired physical sensor from one or more of the virtual sensors located in the virtual sensor repository instead of directly from the desired physical sensor.
