Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Server-level backup energy storage devices are bulky, consuming valuable space and often positioned in thermally suboptimal areas, affecting their functionality due to temperature sensitivity.
Innovation Solution
Integrate an energy storage device with a storage controller into a pluggable module installed at the front of a server, allowing each storage controller to have its own independent backup power source, reducing the need for server-level backup power systems and optimizing placement for better cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If server-level backup energy storage devices are used, then backup power capacity is sufficient, but space consumption increases and thermal management deteriorates
Solution Approach 1:
The patent divides the server-level backup power system into multiple distributed storage controllers, each with its own integrated energy storage device. Instead of one large centralized battery, each storage controller has a smaller local backup power source, segmenting the total backup capacity across multiple independent units. This reduces the space required in any single location and improves thermal distribution.
Solution Approach 2:
The patent moves backup power from a vertical stacking arrangement (server-level components stacked in limited space) to a horizontal distribution across multiple storage controllers positioned at the front of the server. This dimensional shift allows better space utilization and thermal management by spreading components across a larger surface area with improved airflow.
2Reliability
If server-level backup energy storage devices are used, then backup power capacity is sufficient, but thermal management deteriorates
Solution Approach 1:
By segmenting the backup power capacity into multiple smaller energy storage devices distributed across storage controllers, the heat generated by each device is reduced and can be more effectively dissipated. This avoids the thermal concentration problem of a single large battery.
Solution Approach 2:
Each storage controller with its integrated energy storage device can be positioned in locations with optimal thermal characteristics, such as areas with better airflow or proximity to cooling components. This allows each local backup power source to operate in its own thermal environment, optimized for its specific location.
3Adaptability or versatility
If integrated energy storage devices are added to storage controllers, then backup power becomes modular and scalable, but device complexity increases
Solution Approach 1:
The patent combines the storage controller and energy storage device into a single integrated module, merging two previously separate functions into one unified component. This integration reduces the number of separate devices needed and simplifies the overall system architecture while maintaining modular scalability.
Solution Approach 2:
The storage controller is designed to perform multiple functions: normal storage operations and backup power supply. By making the storage controller universal and capable of both data management and power backup, the system reduces complexity by eliminating dedicated backup power hardware while maintaining all necessary functions.
4Ease of operation
If storage controllers are positioned at the front of the server, then accessibility and cooling improve, but space for other components may be reduced
Solution Approach 1:
The patent utilizes the front horizontal space of the server chassis, converting previously underutilized front panel area into functional space for storage controllers. This dimensional reorganization allows easy accessibility while maintaining adequate space for other components through optimized spatial distribution.
