Blade Server Management Bus Power Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing blade server systems face challenges in managing power resources efficiently, leading to potential system shutdowns due to power overload, as conventional buses consume significant standby power and impact system configuration, necessitating a solution to prioritize management buses and optimize power distribution.
Innovation Solution
A blade server system with a management bus that has priority over other buses, such as I2C and COM buses, includes a connection board and a management module that determines module configuration information and distributes power accordingly to prevent overload, using a management bus signal group and a first bus signal group to control power application and functional activation of removable modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional buses (I2C, COM) are operated to collect system configuration information, then system configuration management is achieved, but standby power consumption increases significantly
Solution Approach 1:
The patent extracts the power management function from the conventional bus operations by introducing a dedicated management bus that operates independently. The management bus handles configuration information collection and power distribution decisions, while conventional buses (I2C, COM) are disabled or operated only when necessary, thereby reducing their standby power consumption impact.
Solution Approach 2:
The patent changes the operational state of different buses dynamically. The management bus is activated for configuration management, while conventional buses are placed in low-power or disabled states when not needed. This parameter change in bus operation states optimizes power consumption while maintaining configuration management capability.
2Adaptability or versatility
If power is distributed to all modules simultaneously, then system functionality is maximized, but power overload and unpredictable shutdowns occur
Solution Approach 1:
The patent implements dynamic power distribution through the management bus, which continuously monitors system configuration information and adjusts power allocation to modules in real-time. This dynamic approach allows the system to maximize functionality when power is sufficient while preventing overload conditions that cause shutdowns, thereby maintaining reliability.
Solution Approach 2:
The management bus collects configuration information from modules and uses this feedback to make intelligent power distribution decisions. The system monitors module requirements and power availability, adjusting power allocation accordingly to prevent overload while ensuring necessary modules receive adequate power for optimal functionality.
3Reliability
If management bus has priority over other buses, then power distribution control is improved, but bus signal group complexity increases
Solution Approach 1:
The patent segments the bus system into distinct functional groups: a management bus for power distribution and configuration management, and conventional buses (I2C, COM, USB) for specific peripheral functions. This segmentation allows the management bus to operate with priority for power control while conventional buses handle their specialized tasks, reducing overall system complexity through functional separation.

AI summary
A blade server system with a management bus and method for managing the same. The blade server system includes a connection board and a management module. The connection board is used for modular interconnection, including communication paths for conducting signals including a management bus signal group and a first bus signal group. The management module is used for management of the blade server system using signals including the management bus signal group and the first bus signal group. If a module is detected, the management module selects the detected module through the management bus and acquires module configuration information of the detected module through the first bus signal group. Distribution of power from a power source to the blade server system is determined according to system configuration information including the module configuration information of the module so that the power source is prevented from being overloaded.
