Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The imbalance between increasing storage capacity and stagnant performance capability in storage devices leads to operational issues, particularly in data centers with diverse workloads, where it is challenging to ascertain the cause of these issues due to varying configurations and non-uniform equipment.
Innovation Solution

Engineering Contradiction Analysis
1Quantity of substance
If storage density is increased to satisfy data storage needs, then storage capacity is improved, but performance capability does not increase proportionally
Solution Approach 1:
The patent segments storage devices into different performance tiers (high-performance, standard-performance, and low-performance devices) and assigns workloads accordingly. This segmentation allows the system to optimize performance for critical workloads while utilizing lower-performance devices for less demanding tasks, thereby addressing the imbalance between storage capacity and performance capability.
Solution Approach 2:
The patent implements local quality by assigning different performance requirements to different storage devices based on workload characteristics. High-performance storage devices are allocated to workloads requiring fast access, while lower-performance devices handle less demanding workloads. This localized optimization ensures that performance capability is matched to actual needs rather than uniformly applied across all storage capacity.
2Quantity of substance
If storage devices of varying configurations are deployed incrementally, then storage capacity is expanded, but it becomes difficult to ascertain the cause of operational issues
Solution Approach 1:
The patent implements a feedback mechanism that continuously monitors storage device performance metrics and compares them against expected benchmarks. The system automatically identifies underperforming devices and initiates diagnostic workflows, providing feedback loops that simplify the detection and measurement of operational issues across heterogeneous storage configurations.
Solution Approach 2:
The patent creates a universal management framework that handles diverse storage device configurations through standardized interfaces and common diagnostic procedures. This universal approach allows the system to manage incrementally deployed storage devices of varying configurations while maintaining consistent monitoring and diagnostic capabilities across the entire storage infrastructure.
3Productivity
If workload demand is not properly quantified, then storage resources are inefficiently allocated, but performance optimization cannot be achieved
Solution Approach 1:
The patent transforms complex workload characteristics into simplified demand factor parameters that quantify workload intensity and performance requirements. By changing the representation of workload data from raw metrics to standardized demand factors, the system enables efficient resource allocation and performance optimization without being overwhelmed by the complexity of analyzing all individual workload parameters.

AI summary
Workload on an aggregation of storage devices can be quantified in terms of demand on the aggregation of storage devices and demand on logical storage containers configured on the aggregation of storage devices. The demand on the aggregation of storage devices and the demand on logical storage containers thereon are calculated in a manner that captures demand on both storage capacity and performance capability. Capturing demand on both storage capacity and performance capability facilitates intelligent management that accounts for the relationship between storage capacity and performance capability. This allows the owner/operator of the storage equipment to use storage capacity at a desired (or requested) performance.
