Peripheral Device Optimization via BMC Sideband Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems lack efficient management of peripheral device power and performance optimization in low-power states, as in-band optimization services are unavailable during these states.
Innovation Solution
Implementing a baseboard management controller (BMC) to manage optimization settings out-of-band, leveraging P3O payload generator to provide optimization information to the BMC, which extends optimization capabilities to reduced-power operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If in-band optimization services are used to manage peripheral device power and performance, then optimization can be achieved when the processor is powered, but optimization management becomes unavailable when the processor enters low-power states
Solution Approach 1:
The patent introduces a baseboard management controller (BMC) as an intermediary device that operates out-of-band to manage peripheral device optimization settings. The BMC can access and modify P3O settings independently of the processor's power state, ensuring continuous optimization management capability even when the processor is in low-power modes. This mediator approach resolves the contradiction by decoupling optimization management from processor availability.
2Ease of operation
If the processor manages optimization settings continuously, then optimization control is maintained, but power consumption increases during low-power states
Solution Approach 1:
The system implements self-service by enabling the BMC to autonomously manage peripheral device optimization settings without requiring processor intervention. The BMC can independently read, modify, and write P3O settings based on system power state and optimization policies, eliminating the need for the processor to remain active for optimization management. This allows the processor to enter low-power states while optimization management continues through the BMC's self-service capabilities.
