JBOD BMC Module Remote Management via Switch Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current JBOD apparatuses lack remote connection and management capabilities, requiring physical presence for control and maintenance, and have a complex text-command based interface, making user management inconvenient and technically challenging.
Innovation Solution
Incorporating a BMC module that connects to Ethernet, allowing remote control commands and firmware updates, with a switch to enable interactive operations between the BMC module and HDD expander, and a stand-by power feature for continued remote access even after the JBOD apparatus is powered off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a terminal with text-command interface is used for JBOD management, then remote management capability is provided, but the technical barrier for users becomes very high
Solution Approach 1:
The patent introduces a server as an intermediary between the user and the JBOD apparatus. The server runs management software that provides a simplified interface to users, while handling the complex text-command communications with the JBOD apparatus in the background. This mediator absorbs the complexity, allowing users to manage JBOD without directly facing the complex text-command interface.
2Adaptability or versatility
If multiple cables are used for data access and management, then both host connection and terminal management are enabled, but user convenience significantly decreases
Solution Approach 1:
The patent makes the terminal serve multiple functions: it is used both for data access to the JBOD apparatus and for management operations. By enabling the terminal to handle both data transmission and management commands through a unified interface, the system eliminates the need for separate connection configurations, thereby improving user convenience while maintaining versatility.
3Ease of operation
If physical presence is required for JBOD management, then direct control is possible, but remote management capability is lost
Solution Approach 1:
The patent replaces the mechanical requirement of physical presence with an electronic communication system. By using network protocols and software interfaces, the system enables remote management operations without requiring the user to be physically present at the JBOD apparatus location, thus achieving remote management capability.

AI summary
A JBOD apparatus (1) having a hard disk drive (HDD) expander (11), a switch (13) and a BMC module (12) is disclosed. The HDD expander (11) is connected to a plurality of hard drives (5) respectively. The switch (13) connects the HDD expander (11) with a connecting port (14) for enabling a first transmission channel, or connects the HDD expander (11) with the BMC module (12) for enabling a second transmission channel. The BMC module (12) is connected to an Ethernet through a network port (17). The HDD expander (11) initially receives a wired transmitted command through the first transmission channel. When the BMC module (12) receives an Ethernet transmitted command through the Ethernet, it controls the switch (13) to change for enabling the second transmission channel, therefore, the BMC module (12) executes an interactive operation with the HDD expander (11) in accordance with the Ethernet transmitted command.
