Abstract: An information handling system determines a system configuration including a hardware module, and determines an adjusted power budget for the hardware module. The adjusted power budget is based on a calculation including a difference between a date code read from the hardware module and a baseline date, a baseline power budget, a power reduction period and a power reduction interval. The calculation may optionally include a risk factor. In alternate embodiments, an adjusted power budget for a hardware module may be calculated by an order processing system for information handling systems, or by a planning tool for a data center which contains information handling systems.

Abstract: An authorized information handling system (IHS) generates unique identifier codes for an OEM (programmable) device designed as a component for an IHS. An identifier generation and validation (IGV) controller in the authorized IHS generates a unique encrypted sequence by encrypting identification (ID) data read from the OEM device. The IGV controller generates a unique OEM identifier code by further encrypting the encrypted sequence using a first OEM proprietary code. The IGV controller writes the first identifier code to a pre-specified storage location of the OEM device. According to one embodiment, the IGV controller generates the unique OEM identifier code using a second reversible encryption-decryption component that comprises an Exclusive-OR (XOR) scrambler engine and generates the unique encrypted sequence using a first reversible encryption-decryption component that comprises an LFSR based scrambler, which utilizes polynomial coefficients that are securely generated and maintained.

Abstract: A method validates whether a component/device installed within an information handling system (IHS) is an OEM (original equipment manufacturer) programmed device, by: reading identification (ID) data and an identifier code from the target device; generating a unique encrypted sequence using the ID data; providing a unique validation check code based on the ID data; generating a component validation code corresponding to the target device via a decryption process involving the unique encrypted sequence; and comparing the component validation code to the validation check code. The method further includes: in response to the component validation code matching the validation check code, identifying the target device as an OEM programmed device with a valid identifier code stored as the identifier code; and enabling certain processes reserved for only verified OEM programmed devices. The decryption process reverses an encryption process utilized when generating the unique OEM identifier code of the target device.

Abstract: Systems and methods are provided for supporting use of non-volatile memory (NVM) on a double data rate (DDR) memory channel for an information handling system so that non-volatile memory devices (e.g., such as Phase Change Memory “PCM” devices) may be employed for main memory usage.
