Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In information processing systems, redundant configurations lead to increased power consumption due to unnecessary activation of modules in standby states, which can result in prolonged switching times and inefficient resource allocation.
Innovation Solution
An information processing apparatus that stores permission times for switching between activation and standby states, allowing the processor to determine which modules to stop based on activation times, ensuring that the total activation time for stopping modules is within the specified permission time, thereby reducing power consumption without extending switching times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If modules in the standby apparatus are kept activated to enable rapid failover, then switching time is reduced, but power consumption increases
Solution Approach 1:
The patent applies local quality by differentiating the activation state of modules based on their specific characteristics. Instead of uniformly activating all modules in the standby apparatus, the system selectively activates only those modules with short activation times, while keeping modules with long activation times in a low-power state. This resolves the contradiction by optimizing power consumption without compromising overall system reliability.
Solution Approach 2:
The system dynamically adjusts the activation state of modules based on real-time conditions. The management apparatus determines which modules to activate in the standby apparatus by considering the current operation state of the active apparatus and the activation time characteristics of each module. This dynamic approach allows the system to balance power consumption and switching time requirements adaptively.
2Reliability
If all modules are activated in the standby apparatus, then failover capability is improved, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent implements partial action by activating only a subset of modules in the standby apparatus rather than all modules. The management apparatus identifies and activates only those modules that are critical for maintaining failover capability, based on their activation time characteristics. This partial activation approach maintains sufficient reliability while significantly improving resource allocation efficiency by avoiding unnecessary activation of non-critical modules.
3Speed
If modules with long activation times are kept ready, then switching speed is improved, but power consumption increases
Solution Approach 1:
The system changes the operational parameters of modules based on their activation time characteristics. Modules with long activation times are kept in a low-power state rather than being fully activated, while modules with short activation times are activated to provide rapid response capability. This parameter-based differentiation resolves the contradiction between switching speed and power consumption by optimizing the state of each module according to its specific characteristics.

AI summary
An information processing apparatus includes a memory and a processor coupled to the memory. The memory stores first information and second information. The first information includes a permission time with respect to each of a plurality of operation states of the information processing apparatus in an activation state. The permission time is a time allowed for switching a substitute apparatus from a standby state to the activation state. The second information includes an activation time required for activating each of a plurality of modules which operate on the substitute apparatus. The processor identifies one permission time corresponding to a current operation state. The processor determines stop modules such that a total time for activating the stop modules is equal to or less than the one permission time based on the second information. The processor instructs the substitute apparatus in the standby state to stop the stop modules.
