LPAR Migration Broker Optimizing Server Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for transferring logical partitions (LPARs) between server computing devices do not effectively consider customer requirements such as server operating capabilities and hosting costs, leading to inefficient resource allocation and increased costs.
Innovation Solution
A system and method for transferring LPARs between server computing devices based on customer-specified requirements, utilizing a datacenter broker to match LPAR hosting costs and server operating capabilities, and a migration manager to select and migrate the LPAR to an optimal server, thereby optimizing resource allocation and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If LPAR migration is performed without considering server operating capabilities and hosting costs, then migration simplicity is maintained, but resource allocation efficiency deteriorates and costs increase
Solution Approach 1:
The patent introduces a broker as an intermediary component that manages LPAR migration decisions. The broker receives migration requests, evaluates server capabilities and costs, and determines optimal migration targets. This intermediary layer handles the complexity of cost and capability analysis, keeping the migration process transparent and manageable while improving resource allocation efficiency through informed decision-making.
Solution Approach 2:
The system implements feedback mechanisms where the broker continuously monitors server operating capabilities and hosting costs, using this information to make intelligent migration decisions. The broker evaluates current server states, compares alternatives, and selects migration targets that optimize resource allocation. This feedback-driven approach ensures that migration decisions are based on up-to-date information about server performance and cost metrics.
2Loss of energy
If LPAR migration considers multiple server criteria (operating capabilities and hosting costs), then cost optimization improves, but migration decision complexity increases
Solution Approach 1:
The broker serves as an intermediary that centralizes the complex task of evaluating multiple server criteria. It aggregates information about server operating capabilities and hosting costs from various sources, processes this data according to defined policies, and presents simplified migration recommendations. This intermediary approach manages the complexity of multi-criteria evaluation while enabling cost optimization through systematic analysis.
Solution Approach 2:
The system changes the parameters used in migration decisions from simple operational metrics to include both operating capabilities and hosting costs. The broker evaluates servers based on multiple parameters simultaneously, weighing different factors according to organizational priorities. This parameter expansion enables comprehensive cost optimization while the broker manages the increased decision complexity through structured evaluation frameworks.
