Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data storage systems in data centers face risks due to power failures, which can lead to data loss from cache memory in the event of AC power supply failure, as current backup power solutions are insufficient for maintaining data integrity and efficient data routing upon power restoration.
Innovation Solution
A data storage system with rechargeable energy modules, such as supercapacitor or battery modules, is implemented to provide backup power to data storage media, allowing continued operation and data writing during primary power failures, with redundant modules for enhanced reliability and scalability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rechargeable energy modules are added to provide backup power, then data integrity is improved, but device complexity increases
Solution Approach 1:
The backup power system is segmented into multiple independent energy modules, each capable of providing backup power to specific storage devices. This modular approach improves reliability through redundancy while managing complexity by dividing the system into manageable, interchangeable units rather than requiring a monolithic backup power solution.
Solution Approach 2:
The system changes the energy state of storage devices by switching from primary power to backup power provided by rechargeable energy modules. This parameter change enables continued operation during power failures, ensuring data integrity by maintaining power to complete write operations and flush cache memory.
2Reliability
If multiple energy modules are deployed for redundancy, then reliability is improved, but cost and device complexity increase
Solution Approach 1:
The system uses identical copies of energy modules that can be interchangeably deployed. Each module is a standardized unit with the same capabilities, allowing for simple redundancy where multiple copies provide backup power. This copying approach improves reliability through fault tolerance while keeping individual module complexity low and manageable.
3Reliability
If backup power capacity is increased to cover larger power failures, then reliability is improved, but energy storage requirements and device size increase
Solution Approach 1:
Instead of using one large energy storage system, the backup power capacity is segmented into multiple smaller energy modules distributed across the storage system. Each module provides backup power to a subset of storage devices, achieving comprehensive coverage while keeping individual module sizes manageable and physically compact.
