Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data storage systems face challenges in dynamically adjusting resource provisioning to match changing needs, leading to inefficiencies in resource allocation and performance over time.
Innovation Solution
A distributed storage network (DSN) with a managing unit that uses error encoding and decoding techniques, such as Cauchy Reed-Solomon encoding, and a neural network model to predict future loading conditions, allowing for adaptive configuration and optimization of resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed resources are provisioned in data storage systems, then initial needs are met, but the system cannot adapt to changing needs over time
Solution Approach 1:
The patent implements dynamic resource provisioning by continuously monitoring system performance metrics and automatically adjusting resource allocation based on actual usage patterns and predicted future needs, transforming the static resource provisioning model into an adaptive dynamic system
Solution Approach 2:
The system performs preliminary actions by predicting future loading conditions and proactively provisioning resources before peak demand occurs, allowing the storage system to anticipate and prepare for changing needs rather than reactively responding to them
2Reliability
If resources are over-provisioned to ensure performance, then performance requirements are met, but resource efficiency decreases
Solution Approach 1:
The patent implements continuous feedback loops that monitor actual system performance and resource utilization, using this feedback to dynamically adjust resource allocation and eliminate both over-provisioning and under-provisioning, optimizing the balance between reliability and efficiency
Solution Approach 2:
The system dynamically changes resource allocation parameters based on monitored performance metrics and predicted workload patterns, adjusting provisioning levels to match actual needs rather than maintaining fixed conservative allocations
3Adaptability or versatility
If manual resource adjustment is used, then some adaptability is achieved, but response time to changing conditions increases
Solution Approach 1:
The patent implements self-service automation where the storage system automatically monitors its own performance, predicts future needs, and adjusts resource provisioning without human intervention, enabling rapid response to changing conditions while reducing operational overhead
Data Source
AI summary
A method for execution by a storage network begins by issuing a decode threshold number of read requests for a set of encoded data slices to a plurality of storage units of a set of storage units and continues by determining whether less than a decode threshold number of read requests has been received in a time window. The method continues by identifying one or more encoded data slices encoded data slices associated with read requests of the decode threshold number of read requests that have not been received and for an encoded data slice of the one or more encoded data slices, issuing a priority read request to a storage unit storing a copy of the encoded data slice. The method then continues by receiving a response from the storage unit storing the copy of the encoded data, where the storage unit storing the copy of the encoded data slice is adapted to delay one or more maintenance tasks in response to the priority read request.
