Virtual Backplane for Rack FRU Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blade-based computing systems are limited by proprietary designs, fixed power budgets, and cooling capacities, restricting the ability to seamlessly manage disparate field replaceable units (FRUs) with varying form factors and requirements within a rack-based system, which hinders the integration of high availability and serviceability benefits.
Innovation Solution
A system comprising a frame with virtual slots and a frame center that uses a fixed interconnect topology to enable central, out-of-band management of FRUs with different form factors, power, and cooling requirements, allowing for seamless power distribution, management, and hot-swapping within a rack-based system, mimicking the benefits of blade-based systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blade-based systems are used to achieve unified management and high availability, then serviceability and availability are improved, but adaptability to diverse FRU form factors and requirements deteriorates due to proprietary designs
Solution Approach 1:
The virtual backplane system provides universal management capabilities that work across multiple FRU types and form factors. The frame center can manage diverse FRUs including servers, storage devices, and networking equipment through a unified out-of-band management interface, eliminating the need for proprietary blade enclosure designs while maintaining high availability through centralized control and monitoring
2Stability of the object's composition
If fixed power budgets and cooling capacities are implemented in blade enclosures, then system stability is improved, but flexibility to accommodate FRUs with varying power and cooling requirements deteriorates
Solution Approach 1:
The system implements dynamic power and cooling management where the frame center can monitor and adjust power distribution and cooling resources in real-time based on actual FRU requirements. This allows the system to maintain stability through centralized control while adapting to varying power and cooling demands of different FRUs by dynamically reallocating resources as needed
3Adaptability or versatility
If rack-based systems are used to accommodate diverse FRU form factors, then adaptability is improved, but integration of unified management and hot-swapping capabilities deteriorates compared to blade-based systems
Solution Approach 1:
The virtual backplane acts as an intermediary layer between the rack infrastructure and diverse FRUs, providing unified management capabilities. The frame center communicates with all FRUs through standardized interfaces and protocols, enabling centralized monitoring, control, and hot-swapping operations across different FRU types without requiring proprietary integration for each device
4Extent of automation
If proprietary blade enclosure designs are used, then unified management capabilities are improved, but device complexity and proprietary restrictions increase
Solution Approach 1:
The system segments management functions into a separate frame center that operates independently from the rack infrastructure. This allows unified management capabilities to be implemented as a modular component that can manage diverse FRUs through standardized protocols, reducing proprietary restrictions and simplifying the overall system architecture by separating control plane from data plane functions

AI summary
A system for the management of rack-mounted field replaceable units (FRUs) that affords the enhanced availability and serviceability of FRUs provided by blade-based systems but in a manner that accommodates different types of FRUs (e.g., in relation to form factors, functionality, power and cooling requirements, and/or the like) installed within a rack or cabinet.
