Data Storage Enclosure Energy Management via Selective Drive Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In data storage systems, when the temperature of an enclosure exceeds a threshold, all drives are often powered down, leading to data unavailability and inefficient resource management, as existing systems lack proactive measures to manage energy consumption and temperature effectively across multiple enclosures.
Innovation Solution
A method is introduced to determine energy information for each enclosure, including power consumption and temperature metrics, and take proactive actions such as powering down or migrating data before reaching thresholds, by polling enclosures regularly and using standby power supplies to maintain system stability and availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If all drives in an enclosure are powered down when temperature exceeds a threshold, then temperature control is achieved, but data availability and system reliability deteriorate
Solution Approach 1:
The system divides the enclosure into individual drive-level segments, allowing selective cooling of specific drives rather than powering down all drives. This segmentation enables targeted temperature management while preserving data availability through coordinated standby power supply activation and selective drive operation.
Solution Approach 2:
The system activates standby power supplies in advance before temperature thresholds are exceeded, preparing backup power capacity to enable selective drive operation. This preliminary action ensures that when temperature management is needed, the system can immediately switch to selective drive powering without complete shutdown, maintaining data availability.
2Use of energy by moving object
If all drives are powered down to control temperature, then energy consumption is reduced, but system productivity and data access capability worsen
Solution Approach 1:
The system segments power management to individual drives, activating only the minimum number of drives needed for data availability while powering down others for temperature control. This selective segmentation reduces overall power consumption while maintaining productivity through intelligent drive selection based on data location and access requirements.
Solution Approach 2:
The system dynamically changes the operational state parameter of individual drives between active and powered-down states based on temperature conditions and data availability requirements. This parameter change enables flexible power consumption management while maintaining system productivity through coordinated drive state transitions.
3Reliability
If proactive measures are implemented to manage energy and temperature, then system reliability improves, but device complexity and management overhead increase
Solution Approach 1:
The system implements self-service through automated monitoring and control algorithms that independently manage drive power states and temperature control without requiring manual intervention. This self-service capability improves reliability through consistent proactive management while reducing the effective complexity burden on operators, as the system autonomously handles the complex coordination of multiple drives and power supplies.
Solution Approach 2:
The system employs continuous feedback loops that monitor temperature and drive operational states, automatically adjusting power distribution and drive activation decisions. This feedback mechanism improves reliability by responding dynamically to changing conditions while managing complexity through automated closed-loop control rather than manual management.
4Loss of energy
If selective drive powering is implemented, then energy efficiency improves, but measurement and control complexity increases
Solution Approach 1:
The system implements a universal monitoring and control framework that manages multiple drives and power supplies through a single integrated approach. This multi-functional system handles temperature sensing, power state monitoring, and selective activation across all drives uniformly, improving energy efficiency through coordinated control while reducing monitoring complexity by consolidating measurement and management functions into a unified system.

AI summary
Described are techniques for managing a data storage system. First energy information for each of one or more enclosures of the data storage system is determined. Second energy information for the data storage system based on information including the first energy information for the one or more enclosures is determined. It is determined whether any of the first energy information for each of the one or more enclosures and the second energy information for the data storage system are within a predetermined amount of one or more associated thresholds. If it is determined that any of the first energy information for each of the one or more enclosures and the second energy information for the data storage system are within a predetermined amount of one or more associated thresholds, one or more actions are taken prior to reaching the one or more associated thresholds.
