Rack FRU Interconnection via Virtual Slots and Blind-Mate Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Blade-based computing systems have limitations such as proprietary designs, fixed power and cooling budgets, and restricted upgrade capabilities, which hinder the seamless management of disparate field replaceable units (FRUs) with varying form factors, power, and cooling requirements within a rack-based system, limiting their availability and serviceability.
Innovation Solution
A system comprising a frame with virtual slots and a frame center that enables blind-mate electrical connections and central management, allowing for the detection and management of FRUs with different form factors, power, and cooling requirements, using a fixed interconnect topology that facilitates out-of-band management and automatic integration into a rack-based system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blade-based systems are used to achieve centralized management and hot-swappable FRUs, then availability and serviceability are improved, but adaptability to diverse FRU form factors and power requirements deteriorates
Solution Approach 1:
The rack system employs universal power distribution units (PDUs) and standardized connector arrangements that can accommodate multiple FRU form factors and power requirements. The system provides multi-functionality by supporting both blade-style FRUs and rack-mounted FRUs through the same infrastructure, enabling centralized management while maintaining adaptability to diverse hardware configurations.
Solution Approach 2:
The system segments power distribution and management functions into modular components. Each FRU type can be independently managed through standardized interfaces, allowing the system to handle diverse FRUs with varying power and cooling requirements while maintaining centralized control for availability and serviceability.
2Adaptability or versatility
If manual cabling is required for each FRU connection, then adaptability to different configurations is improved, but installation time and complexity increase
Solution Approach 1:
The rack system pre-configures standardized connector arrangements and power distribution pathways before FRU installation. Power cables and data connections are pre-routed through the rack infrastructure, eliminating the need for manual cabling during FRU installation while maintaining adaptability to different FRU types through standardized interfaces.
Solution Approach 2:
The system enables self-service FRU installation through hot-swappable connectors and automated detection mechanisms. FRUs can be installed and removed without manual cabling operations, as the system automatically detects and configures connections through standardized interfaces, reducing installation time while maintaining configuration flexibility.
3Power
If fixed power budgets are enforced in blade systems, then power management control is improved, but adaptability to FRUs with varying power requirements deteriorates
Solution Approach 1:
The rack system implements dynamic power allocation through intelligent PDUs that can adjust power distribution based on real-time FRU power requirements. Unlike fixed blade system budgets, the rack system allows flexible power allocation that adapts to different FRU types, enabling both centralized power management control and adaptability to varying power demands through automated power provisioning.

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.
