Cluster Aware Container Manager for Heterogeneous Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data storage systems face complexity in managing heterogeneous storage environments and scaling to meet large storage needs, requiring efficient allocation of nodes in a cluster to application containers while minimizing cost and complexity.
Innovation Solution
A method and apparatus that determine node allocation in a cluster using node capacity and policy, publishing the allocation to a coordinator to manage nodes, and instructing a container manager to generate application containers conforming to the allocation, enabling a distributed software platform for managing heterogeneous storage systems as a single logical array.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If nodes in a cluster are allocated to application containers manually, then flexibility in managing heterogeneous storage environments is improved, but system complexity and time consumption increase
Solution Approach 1:
A coordinator component is introduced as an intermediary between the allocation policy and container management. The coordinator receives allocation decisions, translates them into actionable commands, and distributes them to appropriate container managers across the cluster. This intermediary layer abstracts the complexity of heterogeneous storage management, allowing flexible allocation without directly increasing system complexity.
Solution Approach 2:
The system is segmented into independent components: allocation policy module, coordinator, container managers, and storage systems. Each component operates independently with well-defined interfaces, allowing the complex task of managing heterogeneous storage to be divided into manageable segments. This modular architecture reduces overall system complexity while maintaining flexibility.
2Loss of time
If nodes in a cluster are allocated to application containers using automated policies, then time consumption is reduced, but adaptability to heterogeneous storage environments may worsen
Solution Approach 1:
The allocation system is designed to be dynamic, allowing policies to adapt to different storage environments automatically. The coordinator can adjust allocation decisions based on real-time information about storage heterogeneity, performance metrics, and workload requirements. This dynamic capability enables automated allocation to maintain high adaptability without manual intervention.
Solution Approach 2:
The system incorporates feedback mechanisms where the coordinator receives information about allocation outcomes and storage system responses. This feedback loop allows the automated policy to learn from and adapt to heterogeneous storage environments, maintaining flexibility while operating automatically. The feedback enables the system to correct suboptimal allocations and adjust to varying storage characteristics.
3Quantity of substance
If a distributed software platform manages millions of storage volumes, then storage capacity is improved, but system complexity increases
Solution Approach 1:
The coordinator is designed as a universal component that can manage diverse storage volumes through a common interface and unified allocation policy. Rather than requiring specialized management for each storage type, the universal coordinator handles heterogeneous storage systems uniformly, enabling the platform to scale to millions of volumes without proportionally increasing system complexity.

AI summary
In one aspect, a method includes determining an allocation of nodes in a cluster to application containers using a node capacity and a policy, publishing the allocation to a coordinator, the coordinator configured to manage the nodes comprising a first node, reading the allocation from the coordinator and instructing a container manager in the first node to generate an application container in the first node conforming to the allocation.
