Dynamic Power State Control for Storage Device Thermal Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As storage devices, such as those using the PCI Express fifth generation (Gen 5) standard, experience increased frequency and transmission speed, their default operating modes become insufficient, leading to frequent activation of cooling processes and reduced operational stability due to rising temperatures.
Innovation Solution
A power state control method and system that dynamically adjusts the power state of a storage device based on its data access performance, allowing the host system to establish a connection, detect performance, and instruct the storage device to operate within one of several power states within the normal working state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the storage device operates at high frequency and maximum transmission speed, then the data access performance is improved, but the temperature rises above the threshold and cooling processes are activated frequently, reducing operational stability
Solution Approach 1:
The patent applies dynamics by making the power state adjustment adaptive and real-time. The host system dynamically detects data access performance and adjusts the power state accordingly, allowing the storage device to operate at optimal performance when needed while preventing thermal issues when performance demands are lower. This dynamic adjustment resolves the contradiction between maintaining high speed and ensuring operational stability.
Solution Approach 2:
The patent changes the power state parameter dynamically based on detected data access performance. By adjusting the power state between different levels (e.g., PS0-PS4) according to actual performance conditions, the system can maintain high data access speeds when necessary while reducing power consumption and temperature when performance demands are lower, thus resolving the contradiction between speed and operational stability.
2Productivity
If the storage device operates at high frequency and maximum transmission speed, then the data access performance is improved, but the power consumption increases, requiring frequent cooling activation
Solution Approach 1:
The system dynamically adjusts power consumption based on actual data access performance needs. When performance demands are high, the storage device operates at higher power states to maintain productivity. When performance demands are lower, the system transitions to lower power states, reducing energy consumption while maintaining adequate productivity levels.
Solution Approach 2:
The patent implements parameter changes by adjusting the power state parameter according to detected data access performance. This allows the storage device to optimize the balance between productivity and energy consumption, ensuring high data access performance when necessary while minimizing power consumption during periods of lower demand.
3Use of energy by stationary object
If the default operating modes PS0-PS4 are used, then the power consumption and temperature are gradually reduced, but these modes are no longer sufficient for high-frequency and high-speed storage devices
Solution Approach 1:
The patent extends the default operating modes by introducing dynamic power state adjustment capabilities. The host system can now adaptively select from multiple power states (PS0-PS4 and beyond) based on detected data access performance, making the storage device more adaptable to varying operational requirements including high-frequency and high-speed scenarios.
Solution Approach 2:
The patent expands the power state parameter range and introduces dynamic adjustment mechanisms. By allowing the power state to change adaptively based on detected performance, the system gains versatility to handle both low-power scenarios and high-frequency, high-speed operations effectively.
