Multitenant Control Systems for Geographically Dispersed Disaster Restart
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing geographically dispersed disaster restart (GDDR) systems require multiple dedicated mainframe logical partitions, leading to increased hardware costs and complexity, as each GDDR complex needs its own set of control systems, limiting the ability to share resources across different storage configurations.
Innovation Solution
Implementing multitenancy principles in the system design allows multiple GDDR complexes to share the same set of control systems, reducing the number of mainframe logical partitions required by combining individual control systems into a single logical partition, thereby decreasing hardware costs and enhancing system efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple dedicated mainframe logical partitions are used for each GDDR complex, then system autonomy and reliability are improved, but hardware costs and device complexity increase
Solution Approach 1:
Multiple GDDR complexes share a common set of control systems on a single mainframe logical partition, consolidating previously separate control systems into a unified shared infrastructure that reduces hardware requirements while maintaining operational independence through software-based isolation and coordination mechanisms
Solution Approach 2:
The shared control systems are designed to perform multiple functions across different GDDR complexes, enabling a single control system to manage multiple storage configurations and disaster recovery sites simultaneously, thereby reducing the total number of control systems needed while maintaining full functionality for each complex
2Reliability
If multiple dedicated mainframe logical partitions are used for each GDDR complex, then system independence is improved, but system efficiency deteriorates
Solution Approach 1:
Multiple GDDR complexes share a common set of control systems on a single mainframe logical partition, consolidating previously separate control systems into a unified shared infrastructure that reduces hardware requirements while maintaining operational independence through software-based isolation and coordination mechanisms
Solution Approach 2:
The system uses virtualization and software-based isolation to create independent operational environments for each GDDR complex on the shared control system, allowing multiple independent instances to run simultaneously on the same physical infrastructure without interfering with each other
