Server Rack IMM Dynamic Location Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server rack systems face difficulties in dynamically obtaining the exact location of apparatuses, Media Access Control (MAC) addresses, and Internet Protocol (IP) addresses, making it inconvenient and prone to errors, especially in network environments with dynamic address allocation.
Innovation Solution
A server rack system incorporating a network switch, an Integrated Management Module (IMM), and in-rack apparatuses, where the IMM pre-stores correlations between identification information, locations, and management network ports, allowing dynamic location and address management through the network switch, enabling communication with specific apparatuses using their IP addresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual recording of apparatus locations is used, then the system structure remains simple, but the accuracy of location information and the efficiency of address management deteriorate
Solution Approach 1:
The patent introduces a network switch as an intermediary device that automatically records and manages the correlation between apparatus locations, MAC addresses, and IP addresses. This mediator eliminates the need for manual recording while maintaining system simplicity, as the network switch naturally captures this information through its forwarding table mechanisms.
Solution Approach 2:
The system enables self-service by allowing the network switch to automatically maintain location and address information through its inherent network management capabilities. The IMM (Intelligent Management Module) queries the network switch to obtain this information without human intervention, making the system self-managing regarding location tracking.
2Adaptability or versatility
If dynamic address allocation is implemented, then the network adaptability improves, but the difficulty of obtaining MAC addresses and IP addresses corresponding to apparatus locations increases
Solution Approach 1:
The patent implements a feedback mechanism where the IMM continuously queries the network switch to obtain updated correlations between apparatus locations, MAC addresses, and IP addresses. This feedback loop ensures that even with dynamic address allocation, the system maintains accurate and current address-location mappings through automated information retrieval.
3Productivity
If automated network management is implemented, then the operational efficiency improves, but the device complexity increases
Solution Approach 1:
The patent leverages the network switch's existing multi-functionality to achieve automated management. The network switch already performs address forwarding and location tracking as part of its core functions, so no additional dedicated management hardware is needed. The IMM utilizes these existing capabilities to achieve automated efficiency without proportionally increasing system complexity.

AI summary
A server rack system includes a network switch, an Integrated Management Module (IMM) and in-rack apparatuses. The in-rack apparatuses and the IMM are connected to ports of the network switch respectively according to a preset correlation between in-rack locations and the ports of the network switch. The IMM pre-stores a correlation between identification information of the in-rack apparatuses, the in-rack locations and the ports. When the system is in operation, the IMM obtains a correlation between Media Access Control (MAC) addresses of the in-rack apparatuses and the ports from the network switch, and obtains a correlation between the identification information, the in-rack locations and the MAC addresses according to the correlation between the identification information, the in-rack locations, and the ports. The IMM obtains an Internet Protocol (IP) address corresponding to an MAC address, and uses the IP address to communicate with an in-rack apparatus in a specific rack location.
