Virtual Address Assignment for Chassis Management Node Role Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-node chassis without a dedicated chassis management module, seamlessly transferring the chassis administrator role to a designated node for effective management is challenging, as existing methods lack efficient mechanisms for node communication and data management.
Innovation Solution
The method involves obtaining a virtual address for the target node, notifying the corresponding subnet, and using this virtual address to inform other nodes that the target node is the management node, allowing seamless communication and data management through a programmable module without the need for a dedicated management module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated chassis management module is added to enable seamless role transfer and effective management, then management efficiency and reliability are improved, but device complexity and cost increase
Solution Approach 1:
The patent implements self-service by enabling server nodes to autonomously perform chassis management functions. When a node is designated as chassis administrator, it automatically assumes management responsibilities including role transfer, data management, and communication coordination without requiring external dedicated management hardware. The system uses existing node resources (processors, memory, communication interfaces) to provide management services that would traditionally require separate dedicated modules.
2Productivity
If a dedicated chassis management module is implemented, then management efficiency is improved, but cost increases
Solution Approach 1:
The patent applies universality by designing server nodes with multi-functional capabilities. Each node can simultaneously perform computation tasks and chassis management functions. The designated chassis administrator node manages chassis operations while continuing its primary computing functions. This eliminates the need for dedicated management hardware, as existing nodes are configured to handle multiple roles including management responsibilities.
Solution Approach 2:
The patent merges chassis management functions with existing server node functionalities. Instead of separate dedicated management modules, the management capabilities are integrated into the nodes themselves. The chassis administrator node combines data management, communication coordination, and role transfer functions with its primary processing capabilities, reducing overall system hardware requirements.
3Ease of operation
If virtual address assignment and subnet notification mechanisms are implemented, then node communication and role transfer are improved, but system complexity increases
Solution Approach 1:
The patent uses virtual addresses as intermediaries to facilitate communication between nodes and the chassis administrator. Instead of direct node-to-node communication protocols, the system employs virtual address assignment where the designated administrator node receives a specific virtual address that other nodes use to communicate management requests. This simplifies communication by providing a standardized interface through the administrator node.
Solution Approach 2:
The patent implements parameter changes by dynamically assigning virtual addresses to nodes based on their roles. When a node becomes the chassis administrator, its virtual address parameters are updated and propagated to the subnet. This parameter-based approach allows flexible role transfer and communication routing without requiring complex protocol changes, as the system adapts by modifying address parameters rather than communication protocols.

AI summary
An information processing method includes, when determining that a target node in a to-be-processed chassis is used as a management node of the to-be-processed chassis, obtaining a virtual address and assigning the virtual address to the target node, notifying a subnet corresponding to the to-be-processed chassis with the virtual address, and performing communication with a target programmable module of the to-be-processed chassis through the target node and management on data of the to-be-processed chassis. The virtual address is used to inform that the target node is the management node.
