SAN Bandwidth Allocation by Client Priority Groups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Storage Area Networks (SANs) face challenges in managing limited bandwidth across multiple clients accessing the same data storage device, leading to resource competition and suboptimal performance, as existing solutions lack efficient methods to prioritize and allocate bandwidth based on client needs.
Innovation Solution
A method for managing bandwidth in SANs by grouping client devices according to priority and implementing a policy that allocates access parameters, using a resource manager to preferentially allocate bandwidth to higher-priority groups, allowing for dynamic cap and threshold settings to optimize resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If bandwidth is shared among multiple clients in a SAN, then resource utilization increases, but performance optimization for specific clients deteriorates
Solution Approach 1:
The patent applies local quality by assigning different access parameters and priority levels to different client groups. High-priority clients receive preferential bandwidth allocation while low-priority clients receive standard allocation, allowing each client group to receive customized resource distribution based on its specific needs and importance to the system.
2Productivity
If bandwidth allocation is customized for each client, then performance optimization improves, but system complexity increases
Solution Approach 1:
The patent merges multiple clients into priority groups (high-priority and low-priority groups) and applies uniform access parameters to all clients within each group. This grouping strategy reduces the complexity of individual client management while still providing customized bandwidth allocation at the group level, balancing performance optimization with manageable system complexity.
3Adaptability or versatility
If new clients are added to the SAN, then network capacity increases, but resource competition intensifies
Solution Approach 1:
The patent implements dynamic bandwidth allocation that automatically adjusts resource distribution based on current network conditions and client priority levels. When new clients are added, the system dynamically recalculates bandwidth allocation to maintain optimal performance for existing clients while accommodating new additions, ensuring adaptability without exhausting available bandwidth.

AI summary
A method for managing bandwidth allocation in a storage area network includes preparing a policy that defines access parameters for two or more groups of client devices that are grouped according to priority in accessing network resources.
