Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtualization systems fail to optimize memory allocation based on the performance and memory workload of each virtual machine, leading to decreased operating speed due to inefficient memory management.
Innovation Solution
A virtualization apparatus with a memory pool manager that allocates memory based on priority levels, ensuring a guaranteed memory size for high-priority virtual machines and dynamically adjusting memory allocation between virtual machines to maintain performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If memory space is managed based on the efficiency of the use of the whole memory space, then memory usage efficiency is improved, but the operating speed of each virtual machine decreases
Solution Approach 1:
The patent applies local quality by differentiating memory management policies for different virtual machines based on their priority levels. High-priority virtual machines receive guaranteed memory allocation with higher allocation ratios, while low-priority virtual machines receive allocation based on available memory. This localized differentiation resolves the contradiction by ensuring that critical virtual machines maintain adequate memory for performance while overall memory efficiency is improved through dynamic allocation to lower-priority machines.
Solution Approach 2:
The patent implements dynamic memory allocation where the memory pool manager continuously monitors memory usage and adjusts allocation ratios based on priority levels and current memory availability. The allocation ratio for each virtual machine is not fixed but dynamically adjusted according to system conditions, allowing the system to maintain both high memory efficiency and adequate performance for priority virtual machines under varying load conditions.
2Speed
If memory is allocated to maintain performance of a particular virtual machine, then operating speed is improved, but memory usage efficiency of the whole system decreases
Solution Approach 1:
The system uses dynamic allocation ratios that adjust based on priority levels and current memory availability. High-priority virtual machines receive higher allocation ratios (e.g., 70-90% during shortages) while low-priority machines receive lower ratios (e.g., 10-30%), allowing the system to guarantee performance for critical machines while maintaining overall memory efficiency through flexible, condition-based allocation.
Solution Approach 2:
The patent changes the parameter of memory allocation ratio based on priority level and memory availability conditions. By varying this parameter dynamically, the system can ensure adequate memory for high-priority virtual machines when needed while optimizing overall memory utilization by allocating remaining capacity to lower-priority machines, thus resolving the contradiction between performance guarantee and system-wide efficiency.
