Adaptive Power Backup Ride-Through Time Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power backup devices in information handling systems provide a fixed ride-through time that is inefficient, leading to data unavailability and potential loss due to mismatched power consumption and delivery characteristics, as they do not adapt to the specific needs of components during power losses.
Innovation Solution
An adaptive power backup system that monitors power consumption and delivery characteristics to determine a customized ride-through time period, allowing the power storage subsystem to power components for an extended period in systems with low power consumption and a shorter period in systems with high power consumption or degraded power delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a predetermined fixed ride-through time is provided to all memory systems, then the BBU device can operate with simple control logic, but this results in inefficient use of the BBU device causing data unavailability and potential loss
Solution Approach 1:
The patent implements dynamic adjustment of ride-through time based on real-time monitoring of power consumption characteristics of memory systems and power delivery capabilities of the BBU device. The controller continuously adapts the ride-through time parameter rather than using a fixed predetermined value, allowing the system to optimize data protection while efficiently utilizing available power capacity.
Solution Approach 2:
The system incorporates feedback mechanisms where the controller monitors power consumption of memory systems and power delivery characteristics of the BBU device, then uses this information to adjust the ride-through time. This closed-loop control ensures that the ride-through time is optimized based on actual system conditions, improving both reliability and efficiency.
2Duration of action of moving object
If a long predetermined ride-through time is provided, then low power consuming memory systems can maintain operation during power loss, but high power consuming memory systems may exceed BBU power delivery capabilities causing data loss
Solution Approach 1:
The patent applies different ride-through time values to different memory systems based on their individual power consumption characteristics. Instead of a uniform approach, each memory system receives a customized ride-through time that matches its specific power requirements and the BBU's power delivery capabilities, preventing both premature data unavailability and potential data loss from excessive power demand.
Solution Approach 2:
The system dynamically changes the ride-through time parameter based on monitored power consumption and power delivery characteristics. The controller adjusts this critical parameter in real-time to match actual system conditions, ensuring that the ride-through time is extended when power availability permits and reduced when power constraints are detected, thereby preventing data loss.
3Reliability
If a short predetermined ride-through time is provided, then high power consuming memory systems can be protected from exceeding BBU power delivery capabilities, but low power consuming memory systems will experience unnecessary data unavailability
Solution Approach 1:
The patent implements memory-system-specific ride-through time values tailored to each system's power consumption profile. Low power consuming memory systems receive extended ride-through times that allow them to maintain operation longer during power loss, while high power consuming systems receive appropriately limited times. This localized customization eliminates unnecessary data unavailability for low-power systems while maintaining protection for high-power systems.

AI summary
A power consumption/power backup-based ride-through system includes a power supply system that is configured to supply power to the one or more components. A power backup device is coupled to the one or more components and the power supply system, and operates to monitor an amount of power provided by the power supply system to the one or more components. Based on the amount of power provided by the power supply system to the one or more components, as well as characteristics of the power backup device in some embodiments, the power backup device determines a ride-through time period for which the power backup device is capable of powering the one or more components. When the power backup device detects a loss of power to the one or more components, it powers the one or more components for the ride-through time period.
