Power Control Mechanism for Archival Storage Enclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing volume of data stored by companies leads to high costs due to the need for maintaining large numbers of data storage devices, especially in archival storage systems where data is rarely accessed, necessitating a cost-effective solution for managing and storing large quantities of infrequently accessed data.
Innovation Solution
The implementation of multiple-data-storage-devices cartridges that utilize low-cost, high-density data storage devices with limited lifespans, where power is efficiently managed through a power control mechanism that selectively powers only the necessary devices via a network cable, allowing for a power-saving architecture that extends device lifespan and reduces overall costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If power is continuously supplied to all data storage devices in archival storage systems, then data accessibility is maintained, but operational costs and energy consumption increase significantly
Solution Approach 1:
The system implements periodic power cycling of storage devices by placing them in sleep mode during idle periods and activating them only when data access is required. The controller manages power states dynamically, transitioning devices between active and sleep modes based on access patterns, thereby reducing energy consumption while maintaining data accessibility when needed.
Solution Approach 2:
The patent applies dynamic power management where the controller continuously monitors system state and adjusts power supply to individual storage devices in real-time. Devices are selectively powered on or off based on current access requirements, creating a dynamic power allocation system that optimizes energy usage while ensuring data accessibility when required.
2Reliability
If high-quality components are used in data storage devices, then device lifespan and reliability are extended, but manufacturing costs and system complexity increase
Solution Approach 1:
The system employs lower-cost storage devices with limited lifespans (designed for approximately 10 access cycles) in archival applications where data is accessed infrequently. The controller manages these devices through careful power cycling and access optimization, allowing the use of cheaper components while maintaining system reliability through redundancy and controlled usage patterns.
Solution Approach 2:
The patent changes operational parameters by limiting the number of access cycles for archival storage devices and optimizing power state transitions. By modifying access patterns and power management parameters, the system extends the effective lifespan of lower-quality components without requiring high-end hardware, thereby reducing system complexity and cost.
3Quantity of substance
If a large number of data storage devices are deployed for high-density archival storage, then storage capacity increases, but power management complexity and operational costs increase
Solution Approach 1:
The system segments the large array of storage devices into multiple independent zones or groups, each managed by the controller through standardized power management protocols. This segmentation allows the controller to manage power states of individual devices or groups independently, reducing overall power management complexity while maintaining high storage capacity through scalable device addition.
Data Source
AI summary
A method of power management of a multiple-data-storage-devices enclosure is disclosed. In some embodiments, the method includes: receiving a network connection and power from a data connection port detachably coupled to a network cable; identifying a subset of data storage devices within the enclosure to activate; powering off components within the enclosure other than the subset of the data storage devices; for each data storage device in the subset that is not yet powered, activating the data storage device by: monitoring power consumption drawn from the data connection port; identifying a sequence of components associated with the data storage device, wherein the components within the sequence, when powered, together provide access to the data storage device; and powering on each component in the sequence when a previous component in the sequence has reached a steady state power consumption level, wherein when activating the data storage device, power supplied to power on the sequence of the components does not exceed a total power available from the data connection port.
