Low Power Archival Storage Enclosure Cartridge Segmentation
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 high-density and low-power data storage architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple data storage devices are maintained in archival storage systems, then data storage volume and density are improved, but system cost and power consumption increase
Solution Approach 1:
The system divides the data storage devices into multiple cartridges, each containing one or more storage devices. This segmentation allows the system to manage power consumption at the cartridge level rather than managing individual devices, enabling selective powering of entire cartridges based on access patterns and reducing overall power consumption while maintaining high storage volume capacity.
Solution Approach 2:
The system dynamically adjusts the power state of cartridges based on access requirements. Cartridges can be transitioned between powered and unpowered states, allowing the system to optimize power consumption by only powering cartridges that need to be accessed, rather than maintaining all storage devices powered continuously.
2Quantity of substance
If multiple data storage devices are maintained in archival storage systems, then data storage volume is improved, but system cost increases
Solution Approach 1:
Multiple data storage devices are merged into single cartridges that function as unified storage units. This merging reduces the complexity of managing individual devices by treating them as a single logical unit, simplifying power management, access control, and maintenance operations, thereby reducing system cost despite maintaining high storage volume.
Solution Approach 2:
The system uses lower-cost storage devices with shorter expected lifespans within the cartridges, accepting that these devices will need periodic replacement. This approach reduces immediate system cost by using more economical storage components rather than investing in expensive, long-lasting storage devices, while the cartridge structure provides a manageable unit for replacement.
3Ease of operation
If power is supplied to all data storage devices, then data accessibility is improved, but power consumption increases
Solution Approach 1:
The system segments data storage into separate cartridges, allowing selective activation of only those cartridges containing data that needs to be accessed. This segmentation enables the system to maintain data accessibility for active datasets while powering down cartridges with inactive data, significantly reducing overall power consumption.
Solution Approach 2:
The system pre-positions data in cartridges and maintains the ability to quickly activate specific cartridges when data access is needed. By having data pre-stored in organized cartridge structures and maintaining rapid activation capabilities, the system ensures data accessibility is preserved while minimizing the time and power required for data retrieval operations.
Data Source
AI summary
A method of controlling power within a multiple-data-storage-devices enclosure is disclosed. In at least one embodiment, the method comprises receiving a network connection and power from a data connection port to which a network cable is removably coupled; identifying one or more target data storage devices within the multiple-data-storage-devices enclosure to activate, wherein the one or more target data storage devices are a subset of all data storage devices within the multiple-data-storage-devices enclosure; powering off at least one of the data storage devices that draws power from the data connection port to make available additional power to supply from the data connection port; and powering the target data storage devices with the power received through the data connection port to activate the target data storage devices after all other data storage devices are powered off.
