Management Computer Automated Standby Server Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computer systems with multiple servers, existing technologies face challenges in automatically setting a standby server coupled to a different port as the active server's standby, leading to increased I/O load and complex configuration management, especially in large systems where time and labor are required to set up path information across multiple active servers.
Innovation Solution
A method involving a management computer that detects a switch trigger, generates a virtualized storage area, maps logical storage devices, and boots the standby server, allowing automatic selection and configuration of a standby server on a different port without requiring prior settings on the active server's path information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the standby server is coupled to the same port as the active server, then the storage apparatus can manage host groups easily, but the I/O load increases due to multiple servers on one port
Solution Approach 1:
The invention segments the storage apparatus configuration by creating separate host group settings for different ports. Each port can have its own host group, allowing standby servers on different ports to be independently configured without affecting the active server's port configuration. This segmentation resolves the contradiction by enabling easy configuration while distributing I/O load across multiple ports.
2Object-generated harmful factors
If the standby server is coupled to a different port from the active server, then I/O load is reduced, but the administrator must manually provide path information settings for multiple active servers
Solution Approach 1:
The invention implements self-service by allowing the standby server to automatically acquire path information settings from the storage apparatus without manual administrator intervention. The storage apparatus automatically provides the necessary configuration data when the standby server connects to a different port, eliminating the need for manual path information setup while maintaining reduced I/O load.
3Reliability
If path information settings are manually provided for each active server, then the standby server can access storage correctly, but it takes time and labor to grasp individual server configurations in large systems
Solution Approach 1:
The invention introduces feedback mechanisms where the storage apparatus automatically responds to the standby server's configuration requests with the necessary path information. This automated feedback loop eliminates the need for administrators to manually review and provide path settings for each active server, significantly reducing setup time while ensuring correct storage access through automated configuration propagation.
