Storage Resource Selection for DR Volume Copy Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In self-service-type infrastructure operations, ensuring that performance requirements are met for volume copy pairs in disaster recovery configurations is challenging, particularly in cloud environments, where infrastructure administrators need to verify that defined service levels are satisfied post-failover.
Innovation Solution
A storage management apparatus that includes a processor and storage device, managing storage resource information to determine if performance requirements are met at both the main and remote sites, and creating volume copy pairs only when suitable storage apparatuses are available to maintain performance post-failover.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If storage apparatuses are configured uniformly in self-service-type infrastructure, then disaster recovery performance is improved, but device complexity and resource allocation flexibility worsen
Solution Approach 1:
The system enables application engineers to automatically create volume copy pairs with performance guarantees through self-service operations. The storage management apparatus automatically checks performance requirements and selects appropriate storage apparatuses, eliminating the need for manual configuration verification while maintaining performance standards.
Solution Approach 2:
The system performs preliminary checks of storage apparatus performance capabilities before creating volume copy pairs. By verifying performance requirements in advance and pre-selecting suitable storage apparatuses, the system ensures disaster recovery performance without requiring complex post-configuration verification or uniform pre-configuring of all storage apparatuses.
2Manufacturing precision
If performance requirements are strictly verified for volume copy pairs, then service level quality is improved, but operation time and complexity worsen
Solution Approach 1:
The storage management apparatus automatically receives performance requirements, checks them against storage apparatus capabilities, and provides feedback on whether the requirements can be satisfied. This automated feedback loop enables strict performance verification without manual intervention, maintaining service level quality while reducing operation time.
Solution Approach 2:
The system replaces manual performance verification processes with automated electronic checking mechanisms. The processor automatically compares performance requirements with storage apparatus capabilities, substituting manual verification operations with automated computational processes that are both precise and time-efficient.
3Productivity
If storage apparatus performance is optimized for main site, then main site performance is improved, but remote site performance may worsen
Solution Approach 1:
The system allows different storage apparatuses at main and remote sites to have different performance characteristics optimized for their specific roles. The storage management apparatus selects appropriate storage apparatuses for each site based on local performance requirements, enabling main site apparatuses to be optimized for high-performance operations while remote site apparatuses are selected for their suitability for backup and recovery operations.
Data Source
AI summary
An apparatus stores storage resource management information for managing information on a throughput performance resource and a response time of a storage apparatus in each of a main site and a remote site. The apparatus receives a performance requirement including response performance and throughput performance for a volume copy pair including a primary volume in the main site and a secondary volume in the remote site. The apparatus determines whether there is a storage apparatus satisfying the performance requirement in both the main site and the remote site with reference to the storage resource management information. When there is a storage apparatus satisfying the performance requirement in both the main site and the remote site, the apparatus determines to create the volume copy pair.
